The IC Series Inverter/Charger has the automatic neutral to ground switching feature enabled as a factory default setting. In some installations this feature must be physically disabled by disconnecting the neutral to chassis ground connection. Please consult your local code requirements to see if this feature must be physically disconnected.
The chassis ground connection (used for AC and DC grounding) on the outside of the Inverter/Charger should still be connected to the system’s earth ground, even if the ground to neutral switching has been disabled.
WARNING: Disconnect all AC and DC power sources before working in the AC terminal wiring area.
1. Remove the AC cover plate.
2. Locate the two ground terminals. To the left of these connectors is a Phillips screw. This screw must be unscrewed and removed from the compartment. Keep this screw in a safe place.
3. Re-attach the AC cover plate.
