3 WIRING
CAUTION
앫
To prevent a malfunction due to noise, keep the signal cables more than 10cm away from the power cables.
앫
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 a control box etc., take care not to allow chips and other foreign matter to enter the inverter.
앫
Set the voltage/current input switch in the correct position. An incorrect setting may cause a fault, failure or malfunction.
