5.11 DO Connection
The inverter has integrated a DO relay for an earth fault alarm. The additional equipment
required is a light indicator and/or a buzzer that needs to be powered by an external
power not higher than 30 V DC.
Once the inverter receives the earth fault signal, the relay closes the contactor. The relay
remains triggered until the fault is removed.
Refer to section "5.8.1 Assembling the COM Connector" for detailed assembling
procedure. Plug the wires to NNOO and CCOOMM terminals according the labels on the bottom
of the inverter.
Refer to section "5.9.3 Installing the COM Connector" to install the connector.
