DC Wiring for a Dual-Inverter System
1. Remove positive distribution plate attached to bottom terminal on existing DC
disconnect/breaker.
2. Install second DC disconnect/breaker (supplied in 865-1020) next to existing DC
disconnect/breaker.
3. Replace the factory-installed DC positive bus bar with the larger positive bus bar
provided in the 865-1020. This larger DC positive bus bar supports up to three
GJ250 Adc disconnect/breakers.
4. Connect positive battery cable for second inverter (supplied in 865-1020) to top
terminal on second DC disconnect/breaker.
5. Connect negative battery cable for second inverter (supplied in 865-1020) to DC
negative distribution plate.
6. Connect positive and negative battery cables to second inverter.
7. Remove knockout on the lower cover for additional disconnect/breaker to fit through.
8. Re-install lower wire cover.
Important:
When installing more than one inverter at a location, a XW
System Control Panel will be required to give each inverter (as well as other
Xanbus-enabled devices) a unique name and to modify the factory-installed
default settings to match and support the installed configuration.
