NOTE
y
To prevent a malfunction caused by noise, separate the signal cables more than 10cm 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.
