CAUTION

•To prevent a malfunction caused by noise, separate the signal cables more than 10cm from the power cables.

•During wiring, do not leave wire off-cuts in the inverter.

Wire off-cuts will cause an alarm, failure or malfunction. Always keep the inverter clean. W hen drilling mounting holes in a control box etc., take care not to allow chips and other foreign matter to enter the inverter.
