Warning All modules must be installed by licensed electricians in accordance to the applicable electrical codes such as, the latest National Electrical Code (USA) or atakale Electric Code (Canada) or other national or international applicable electrical codes
Warning Before attempting to install, wire, operate and / or service the module and other electrical equipment, all instructions should be read and understood. PV module connectors pass direct current (DC) when exposed to sunlight or other light sources. Contact with electrically active parts of the module, such as terminals, can result in injury or death, irrespective of whether or not the module and the other electrical equipment have  been connected
All modules must be installed by licensed electricians in accordance to the applicable electrical codes such as, the latest National Electrical Code (USA) or atakale Electric Code (Canada) or other national or international
applicable electrical codes. 

  Protective clothing (non-slip gloves, clothes, etc.) must be worn during installation to prevent direct contactwith 30 V DC or greater, and to protect hands from sharp edges.
 Prior to installation, remove all metallic jewelry to prevent accidental exposure to live circuits.
 When installing modules in light rain, morning dew, take appropriate measures to prevent water ingress into the connector.
  Do not allow children or unauthorized persons near the installation site or storage area of modules.

 Do not install modules in strong wind. · Use electrically insulated tools to reduce the risk of electric shock. · If the disconnects and Over Current Protection Device (OCPD)'s cannot be opened or the inverter
cannot be powered down, cover the fronts of the modules in the PV array with an opaque material to stop the production of electricity when installing or working on a module or wiring.
· Do not use or install damaged modules. · Contact with module surfaces or frames may cause electric shock if the front glass is broken or the backsheet is torn. · The PV module does not contain any serviceable
parts. Do not attempt to repair any part of the module. · Keep the junction box cover closed at all times
· Do not disassemble a module or remove any
module part.
· Do not artificially concentrate sunlight on a module.
· Do not connect or disconnect modules when
current from the modules or an external source is

Module electrical ratings are measured under Standard Test Conditions (STC) of 1000 W/m2 irradiance, with an AM1.5 spectrum, and a cell temperature of 25°C. Detailed electrical and
mechanical characte- ristics of atakale Solar Inc. crystalline silicon PV modules can be found in Annex C (Mechanical and Electrical Ratings) on
Main electrical characteristics at STC are also stated on each module label. Please refer to the datasheet or the product nameplate for the maximum system voltage.
Under certain conditions, a module may produce more current or voltage than under its Standard Test Condition's rated power. As a result, the module short-circuit current under STC should be multiplied
by 1.25, and a correction factor should be applied to the open-circuit voltage (see Table 1 below), when determining component ratings and capacities. Depending on your local regulations, an additional
1.25 multiplier for the short-circuit current (giving a total multiplier of 1.56) may be applicable when sizing conductors and fuses.

Alternatively, a more accurate correction factor for the open-circuit voltage can be calculated using the following formula: 
CVOC = 1-αVoc ˣ (25 - T)
T is the lowest expected ambient temperature at the system installation site αVoc (%/ºC) is the voltage temperature coefficient of the selected module (refer to corresponding  datasheet)
Electrical calculations and design must be performed by competent engineer or consultant.

· Modules should be stored in a dry and ventilated environment to avoid direct sunlight and  moisture. If modules are stored in an uncontrolled environment, the storage time should be less than 3 months and extra precautions should be taken to prevent connectors from being exposed to moisture or sunlight, like using connector endcaps.
· Unpack module pallets carefully, following the steps shown on the pallet. Unpack, transport and store the modules with care. 
· Modules must always be unpacked and installed by two people. Always use both hands when handling modules.

· Do not stand, step, walk and / or jump on modules under any circumstances. Localized heavy loads may cause severe micro-cracks at cell level, which in turn may compromise module reliability and void atakale Solar Inc’s warranty
· Do not support the module by the backsheet when handling or installing the module.
· Do not carry modules on your head.
· Do not drop or place objects (such as tools) on the modules.
· Do not lift modules by their wires or junction box,lift them by the frame.
· Stacks of modules should contain no more than 12 modules, and the frames should be aligned.
· Do not place excessive loads on the module or twist the module frame.
· Do not use sharp instruments on the modules. Particular care should be taken to avoid module backsheets being damaged by sharp objects, as scratches may directly affect product safety.
· Do not leave modules unsupported or unsecured.
· Do not change the wiring of bypass diodes.
· Keep all connectors clean and dry at all times.
· Do not expose the modules and its connectors to any unauthorized chemical substance (e.g. oil, lubricant, pesticide, etc
· Each module has three identical barcodes (one in the laminate under the front glass, the second on the rear side of the module and the third on the frame) that act as a unique identifier. Each
module has a unique serial number containing 13 (pre March 2013) or 14 (post March 2013) digits. · A nameplate is also affixed to the rear of each mo- dule. This nameplate specifies the model type,
as well as the main electrical and safety characteristics of the module

  · Prior to installing modules please obtain information about any requirements and necessary approvals for the site, installation and inspection from the relevant authorities.
· Check applicable building codes to ensure that the construction or structure (roof, facade, support,etc.) can bear the module system load.
· CS-series solar modules have been qualified for Application Class A (equivalent to Safety Class II requirements). Modules rated under this class should be used in systems operating at voltage above 50 V or power above 240 W, where general contact access is anticipated.
· Atakale Solar Inc. modules have been certified as Type 1 or Type 4 according to UL 1703 and Class C according to IEC 61730-2, please refer to the datasheet or the product nameplate for the detailed types.
· Consult your local authority for guidelines and requirements for building or structural fire safety
· A photovoltaic systems composed of UL 1703 certified modules mounted on a UL 2703 certified mounting system should be evaluated in combination with roof coverings in accordance with UL 1703 standard, with respect to meeting the same fire classification as the roof assembly. · Mounting systems with a System Fire Class Rating (Class A, B or C), tested in conjunction with fire rated “Type 1” or “Type 4” rated modules, are
considered acceptable for use with atakale Solar Inc. modules, provides the mounting system does not violate any other requirements of this manual. · Any mounting system limitations on inclination or
accessories required to maintain a specific System Fire Class Rating should be clearly specified in the installation instructions and UL 2703 certification of the mounting system supplier.· When installing modules, ensure the supporting roof has a fire resistant roof covering rated for the application. · The fire rating for this module is only valid when the product is installed as specified in the mechanical mounting instructions
• The module is intended for use in general open-air climates, as defined in IEC 60721-2-1: Classification of environmental conditions Part-2-1: Environmental conditions appearing in nature - Temperature and humidity.
 • Please consult the atakale Solar Inc. technical support department for more information on the use of modules in special climates, , such as an altitude greater than 2000 m
 Do not install modules near open flames or flammable materials
 Do not immerse modules in water or constantly expose modules to water (either fresh or salt) (i.e. from fountains, sea spray).
    • Exposing modules to salt (i.e. marine environments) or sulfur (i.e. sulfur sources, volcanoes) incurs the risk of module corrosion.
    • Do not expose modules and their connectors to any unauthorized chemical substances (e.g. oil,lubricant, pesticide, etc.), as modules may incur damages.
    • · Failure to comply with these instructions will void atakale Solar Inc. limited warranty.
    • Ensure that the module meets the general technical system requirements
  Ensure that other system components do not damage the module mechanically or electrically. · Modules can be wired in series to increase voltage or in parallel to increase current. To connect modules in series, connect the cables from the positive terminal of one module to the negative terminal of the next module. To connect in parallel, connect the cables from the positive terminal of one module to the positive terminal on the next module.
· The quantity of bypass diodes in the module's junction box may vary depending on the model series. · Only connect the quantity of modules that corresponds to the voltage specifications of the inverters used in the system. In addition modules should not be connected together to create a voltage higher than the maximum permitted system voltage stated on the module nameplate, even under the worst local temperature conditions (see Table 1for the correction coefficients that apply to opencircuit voltage).
· A maximum of two strings can be connected in parallel without the need to incorporate an overcurrent protection device (fuses, etc.) in series within each string. Three or more strings can be connected in parallel if an appropriate, certified over-current protection device is installed in series within each string. And it shall be ensured in the PV system design that the reverse current of any particular string is lower than the module maximum fuse rating at any circumstance.
· For high power density modules such as CS1 series intended to be used on rooftop applications, in agree- ment with IEC 62548: 2016 Photovoltaic (PV) arrays design requirements, blocking diodes should be used in each PV array module string as exclusive mean of protection against reverse currents where three or more strings are connected in parallel. Where permit- ted by your local electrical code, blocking diodes can also be used for overcurrent protection, in place of fuses or other OCPD devices.
· Only modules with similar electrical outputs should be connected in the same string to avoid or minimize mismatch effects in array To minimize risk in the event of an indirect lightning strike, avoid forming loops with
the wiring when designing the system. · The recommended maximum series fuse rating is stated in a table in the Annex C. · Modules should be safely fixed to bear all expected loads, including wind and snow loads.
· A minimum clearance of 6.5 mm (0.25 in) between modules is required to allow for thermal expansion of the frames. · The small drainage holes on the underside of the  module must not be blocked
· To maximize your annual yield, find out the optimum orientation and tilt for PV modules in your region. The highest yields are achieved when sunlight shines perpendicularly onto the PV modules.
· Even minor partial shading (e.g. from dirt deposits) reduces yields. A module can be considered to be unshaded if its entire surface is free from shading all year round. Sunlight should be able to reach the module even on the shortest day of the year.
· Constant shading conditions can affect module service lifetime, due to accelerated ageing of the encapsulation material and thermal stress on the bypass diodes.
• Sufficient clearance (at least 10 cm (3.94 in)) between the module frame and the mounting surface is required to allow cooling air to circulate around the back of the module. This also enables condensation or moisture to dissipate
•According to UL 1703, any other specific clearance required for maintaining a system fire rating should prevail. Detailed clearance requirements pertaining to system fire ratings must be provided 

· Cable management scheme should be reviewed and
approved by the EPC contractor, in particular
required cable lengths should be cross-checked
considering the specificities of the tracker structure
like bearing house gaps. If longer cable or additional
jumper cable is requested, please contact atakale
Solar’s sales representative in advance.
· Do not connect different connectors (brand and
model) together.
· Ensure that the wiring is correct before starting up the system. If the measured open circuit voltage (Voc) and short-circuit current (Isc) differ substantially from the specifications, this indicates that there is a
wiring fault. · When modules have been pre-installed but the system has not been connected to the grid yet, each module string should be kept under open-circuit conditions and proper actions should be taken to
avoid dust and moisture penetration inside the connectors.
· For CS3U, CS3K, CS3W and CS3L series modules, Canadian Solar Inc. offers optional cable specifications to match various system configurations. Recommended system cable schemes are shown in
Table 2 below:

   Table 2: System Cable Scheme

    recommended system cable schemes are shown in Table

The maximum distance between two adjacent module frames should be within 50 mm (1.96 in) for the side with mounting clamps, and within 25 mm (0.98 in) for the side without mounting clamps, in order to meet the system cable scheme


        ◦  Make sure that all connections are safe and properly mated. The PV connector should not be subjected to stress from the exterior. Connectors should only be used to connect the circuit. They

should never be used to turn the circuit on and off. · Connectors are not waterproof when unmated. When installing modules, connector should be connected to each other as soon as possible or appropriate measures should be taken to avoid moisture and dust penetrating into the connector. · Do not clean or precondition the connectors using lubricants or any unauthorized chemical substance.


· Only use dedicated solar cable and suitable connectors (wiring should be sheathed in a sunlight-resistant conduit or, if exposed, should be sunlight-resistant itself) that meet local fire, building and electrical regulations. Please ensure that all wiring is in perfect electrical and mechanical condition.
· Installers may only use single-conductor cable listed and labeled as USE-2 or PV wire which is 90°C wet rated in North America, and single conductor cable, 2.5-16 mm² (5-14 AWG ), 90°C wet rated in other areas (i.e. TUV 2PfG1169 or  EN50618 approved), with proper insulation which is able to withstand the maximum possible systemopen- circuit voltage.
· Only copper conductor material should be used. Select a suitable conductor gauge to minimize voltage drop and ensure that the conductor ampacity complies with local regulations (i.e. NEC 690.8(D))


   ◦ Secure the cables to the mounting system using UV-resistant cable ties. Protect exposed cables from damage by taking appropriate precautions (e.g. placing them inside a metallic raceway like EMT conduit). Avoid exposure to direct sunlight.
A minimum bending radius of 60 mm (2.36 in) isrequired when securing the junction box cables to the racking system. · Do not place connectors in locations where water could easily accumulate


 For grounding requirements in North America, a module with exposed conductive parts is considered to comply with UL 1703 only when it is electrically grounded in accordance with both the instructions presented below and the requirements of the National Electrical Code. Any grounding means used with atakale Solar Inc. modules should be NRTL certified to UL 467 and UL 2703 standards. Please consult our technical service team for the formal approval process.

· For grounding requirements in other areas, although the modules are certified to Safety Class II, we recommend them to be grounded and that module installation should comply with all applicable local electrical codes and regulations.

· Grounding connections should be installed by a qualified electrician.

· Connect module frames together using adequate grounding cables: we recommend using 4-14 mm² (AWG 6-12) copper wire. Holes provided for this  purpose are identified with a grounding symbol(IEC 61730-1). All conductive connection junctions must be firmly fixed.

· Do not drill any extra ground holes for convenien- ce this will void the modules warranty.

· All bolts, nuts, flat washers, lock washers and other relevant hardware should be made of stainless steel, unless otherwise specified.

· atakale Solar Inc. does not provide grounding hardware.

· One grounding method is recommended for Canadian Solar Inc. standard modules, as described below. For alternative grounding methods, please refer to Annex B (Alternative Grounding Methods) of this installation manual. It may not be possible to use standard grounding methods for certain module ranges. Please refer to Annex B for more details.



·  A grounding kit containing an M5 (3/16") SS cap bolt, an M5 (3/16") SS flat washer, an M5 (3/16") SS cup washer, and an M5 (3/16") SS nut (with teeth) is used to attach copper grounding wire to a pre-drilled grounding hole on the frame (see image below).

· Place the wire between the flat washer and the cup washer. Ensure that the cup washer is positioned between the frame and the wire with the concave side up to prevent galvanic corrosion. Tighten the bolt securely using the SS toothed nut. A wrench may be used to do this. The tightening torque is 3-7 Nm (2.2-5.2 ft-lbs).

· Teli düz rondela ile ters  rondela arasına yerleştirin. Galvanik korozyonu önlemek için fincan pulunun içbükey tarafı yukarı gelecek şekilde çerçeve ile tel arasına yerleştirildiğinden emin olun. SS dişli somunu kullanarak cıvatayı iyice sıkın. Bunu yapmak için bir anahtar kullanılabilir. Sıkma torku 3-7 Nm'dir (2,2-5,2 ft-lbs)

 The applicable regulations pertaining to work safety, accident prevention and securing the construction site must be observed. Workers and third party personnel shall wear or install fall arrest equipment. Any third
party need to be protected against injuries and damages. · The mounting design must be certified by a registered professional engineer. The mounting  design and procedures must comply with all applicable local codes and requirements from all relevant authorities.
· The module is considered to be in compliance with UL 1703 and IEC 61215 only when the module is mounted in the manner specified by the mounting instructions included in this installation manual.
· Any module without a frame (laminate) shall not be considered to comply with the requirements of U
1703 unless the module is mounted with hardware  that has been tested and evaluated with the module under this standard or by a field inspection certifying that the installed modulecomplies with the requirements of UL 1703.
· atakale Solar Inc. does not provide mounting hardware. · Standard modules can be mounted onto a support  structure using one of several approved methods. One of such methods is described below. Fordetails of other mounting methods and the methods re- commended by atakale Solar Inc. for special mo- dule ranges, please refer to the Annex A (Alternative Mounting Methods) of this installation
For information about other installation methods, please contact your local representative. Failure to use a recognized installation method will void the atakale Solar Inc. warranty. · Use appropriate corrosion-proof fastening materials. All mounting hardware (bolts, spring washers, flat washers, nuts) should be hot dip galvanized or stainless steel. · Use a torque wrench for installation. · Do not drill additional holes or modify the
module frame. Doing so will void the warranty. 
· Standard modules can be installed in either landscape or portrait orientations. Refer to the detailed instructions for further guidance. Please note that in areas with heavy snowfall (> 2400 Pa) further countermeasures such the use of additional
support bars should be considered to avoid snow loads damaging the lowest row of modules. In cases where an additional support bar is recommended to improve both mechanical stability and long-term module  erformance, we recommend selecting a sufficiently resistant material. atakale Solar Inc. recommends bars with a minimum thickness of 50 mm (1.97 in). The support bar centerline should be positioned within 100 mm (3.94 in) of the side frame centerline (slight shifts may be necessary to access module grounding hole
The loads described in this manual correspond to test loads. For installations complying with IEC 61215-2: 2016 and UL 1703, a safety factor of 1.5 should be applied for calculating the equivalent maximum authorized design loads. Project design loads depend on construction, applicable standards, location and local climate. Determination of the design loads is the responsibility of the racking suppliers and / or professional  ngineers. For detailed information, please follow local structural code or contact your professional structural engineer correctly calculating the loads and ensuring that the supporting structure meets all the applicable requirements
Modules should be bolted at the following hole locations depending on the configuration and loads:
· This mounting method has been qualified by atakale Solar Inc. as well as certified by VDE. and CSA. · Modules should be bolted to supporting structures through the mounting holes in the rear frame flanges only.
· Each module must be securely fastened at a minimum of 4 points on two opposite sides.  M8 X 1.25 - Grade 8.8 (5/16”-18 Grade B7) galvanized or A2-70 stainless steel bolt and nut should be used.
The yield strength of bolt and nut should not be less than 450 MPa. · Tightening torques should be 17~23 Nm (12.5~17.0 ft-lbs) respectively for M8 (5/16”-18) coarse thread bolts, depending on bolt class.
· In areas with heavy wind loads, additional mounting points should be used. The system designer and the installer are responsible for
