2 WIRING

2.1 Terminal connection diagram

· To prevent a malfunction due to noise, keep the signal cables more than 10cm away from the power cables. Also separate the main circuit wire

of the input side and the output side. 

· After wiring, wire offcuts must not be left in the inverter.

Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean.

When drilling mounting holes in an enclosure etc., take care not to allow chips and other foreign matter to enter the inverter.

· Set the voltage/current input switch correctly. Different setting may cause a fault, failure or malfunction.
