The load control mode
has been set via the
LCD menu.
The relay is activated once the
conditions of the control mode are
satisfied. See “10.4.9 Setting Load
Control”.
Once the inverter receives the earth
fault signal, the relay closes the
contact. The relay remains triggered
until the fault is removed.

An AC contactor must be installed between the inverter and
appliances. It is forbidden to connect the load directly to the DO port.
The current of the DO dry contact should not be larger than 3 A.
The DO node is not controlled once the inverter is powered off.
Connect the AC contactor by the manual switch, so as to control the
loads.
