CAUTION
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.
