frequency setting signal is
changed frequently.
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 an enclosure etc., take care not to allow chips and other foreign matter to enter the inverter.

Be sure to connect the DC reactor
supplied with the 01800 or more.
When a DC reactor is connected
to the 01160 or less, remove the
Earth
jumper across P1-P/+.
