When the incorrectly wired inverter is turned on, 120VAC power will energize the shore power connection leading to an increased risk of personal injury.

The remedy is to test the function of the inverter. The only outlets that should be energized are the outlets marked “Off the Grid Inverter Circuit”. If other outlets or appliances are energized the connection at the inverter must be inspected and repaired as needed.

 

REPAIR INSTRUCTIONS

 

Step 1

Locate the trailer on a level, flat, hard surface. Chock the wheels.

 

Step 2

With a fully charged battery connected; disconnect the shore power and turn on the inverter. Inspect outlets labeled “Off the Grid Inverter Circuit”. These should be the only 120VAC circuits energized in the unit. See Figure 1. If these are the only circuits energized proceed to Warranty Reimbursement for inspection only, otherwise proceed to Step 3. 

 

Step 3

If other circuits are energized verify the inverter input and output connections are connected properly.  If the connections are reversed, disconnect 120VAC and 12VDC power to the unit, repair the connections and test the function of the inverter.
