Installing REbus wiring

DANGER
Electrocution. Put the Generac PWRcell Inverter into
Safety Shutdown before installing wiring. If there are any
other batteries connected to REbus, toggle their front
Battery Disconnect switches to OFF. Failure to do so will
result in death or serious injury.
CAUTION
Equipment damage. Never connect REbus conductors
to ground. Connecting REbus conductors to ground
could result in equipment or property damage.
CAUTION
Equipment damage. Connect only to REbus-compatible
devices to the DC bus. Never connect to any other DC
power source. Connecting to other DC power sources
could result in equipment damage.
When installing REbus wiring:
•
Wiring must be installed in accordance with Article
706 in the NEC.
•
Wiring must comply with local electrical codes.
•
Wiring must be grounded according to local codes.
When required, grounding is the responsibility of
the installer. For proper REbus communication,
ensure the chassis is securely bonded to the
PWRcell Inverter via the grounding bar in the
PWRcell Inverter wiring compartment.
•
Wiring must be protected from exposed metal
edges by using appropriate bushings, fittings, and
restraints.
•
Watertight conduit fittings are required for OR
model.
•
Wiring must adhere to the following specifications:
