9. Tighten feet jam nuts to lock them in place.
Installing REbus Wiring
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:
