3 WIRING
CAUTION
To prevent a malfunction due to noise, keep the signal cables more than 10cm away from the power cables.
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 in the correct position. An incorrect setting may cause a fault, failure or malfunction.

*2 To supply power to the control circuit
separately, remove the jumper across
R/L1–R1/L11 and S/L2–S1/L21.
Connect the power to the terminals
R1/L11 and S1/L21 then.
