3.2.2 Load Control

The inverter is equipped with a dry contact relay, which helps turn the loads on or off when an
extra contactor is connected.
Note:
• The AC contactor should be placed between the inverter and the loads. Do not connect the load to DO
port directly.
• The contactor is not supplied by the manufacturer. Connect the the load to the DO port of the inverter
directly if the load is designed with a DI port.
• Maximum voltage and current at DO dry contact port: 250VAC 3A/30VDC 3A.
• When the controlled load is connected to ONGRID, the contactor coil must also be connected to
ONGRID. When the controlled load is connected to BACKUP, the contactor coil must also be connected to
BACKUP.
