WARNING &Installation
1 Installation environment
- No Water drops, steam, dust or oily dust surrounded
- No caustic or inflammable gas and liquid surrounded
- No floating dust and metal particles surrounded
- Solid base without vibration
- No electromagnetic or noise interference
- Ambient temperature should be -10°C ~ +50°C; in case that the ambient temperature is higher than 40°C and that it is overheated, it should be stored in a place where there is good ventilation
2-Installation Instructions and Space Limit
-It should be installed on the fire-proof frame, for example metal frame, in case that it causes fire accidents
-It should be mounted by screws vertically; upside-down, slant or horizontal mounting are not allowed
-Spare space must be ensured for the ventilation of converter in case that it's overheated while it's running
-Ventilation must be taken into consideration to ensure that ambient temperature is lower than specified value when converter is installed inside a control cabinet
-To minimize the heat effect on each other, they should be horizontally installed abreast if two or more converters are installed in the same control cabinet; Baffle plate must be set up between them for the same reason if they have to be installed vertically
-It should be kept away from various impurity, such as fiber, paper scraps, wood chips or metal filing
- PE earth terminal must be connected with the ground
- The rated voltage must be in conformity with AC voltage
-Power cords must be connected with the terminal R, S and T while lines for motor should beconnected with terminal U,V and W; any incorrect connection may cause damage to the internalcomponents of converter
-The reliability of the terminals and wires must be evaluated before wiring, and screws for theterminals of major loop must be fastened solidly.
To avoid electric shock, do not touch the terminals of major loop
1 Connection of input terminal R, S, T or L, N
An additional breaker/chopper must be connected in series with the terminals of major loop(R,S,T or L,N) and three-phase AC or Single-phase AC input. For better running, an electromagnetic contactor should be connected with them in series so that it could cut off the power while the protection function of converter is activated (Tip: R-C surge absorbers should be added to the ends of electromagnetic contactor.
If an additional
earth leakage circuit breaker (ELCB) is installed as a protective device for electric leakage , the sensitivity of current should be more than 200mA while actuation time should be no less than 0.1 second in order to prevent ELCB from ma l function ing.
AC reactor must be connected with the input terminals in case that some of rectifiers are damaged by high voltage and high current input circuit from the grid , which could also improve the power factors of input terminals.
Do not control the converter by adopting the wa y of powering on or off major loop. Instead of that, RUN/STOP buttons on the keyboard or control loop terminals should be applied to the control of converter; if it has to be controlled by that way, it can be implemented only once every one hour.
It's feas ible to reduce the interference with devices nearby by connecting an additional noise filter with the input terminals.
Do not connect converter driven by three phase power to single phase source.
