Wire the IQGateway
The IQCombiner5/5C ships with the IQGatewayPCB pre-wired to
the IQGateway breaker.
For grid-forming systems (with IQSystemController on site), it is
required to power the IQGateway from the IQSystemController.
1. Disconnect the power cables from the IQGateway breaker to
the IQGateway L1, L2 .
2. Connect IQGateway L1 and L2 to the 20 A L1 and L2 terminals,
respectively, of the pre-installed quad breaker on the
autotransformer position in the IQSystemController 3/3G.
Grid-tied systems
NOTE: The IQGateway L2 terminal is shorted to the L3 terminal
using a jumper. While powering the L2 of the IQGateway, loosen
the jumper from the L2 terminal, insert the wire, and then tighten
it to ensure both the wire and jumper are properly installed. Do not
loosen the jumper connection on the L3 terminal.
