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 a control box 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.
