User Manual

Pull cables outwards to confirm whether they are installed firmly.

Connect the three-pole plug to the DO connection sockets.

ON1

COM1

The DO2 relay can be configured as NO (by connecting COM and OFF) or NC (by
connecting COM and ON) contact. The DO1 relay is not configurable.

You must install an external load relay between the inverter and the
consumer load. Do not connect any consumer load directly to the switch
output.
