Inverter Ignition Control (For Freedom HF 1000, 1055,
1800, and 1800 T)
The Freedom HF can be wired to inhibit inverter operation in the absence of
a vehicle’s (or vessel's) ignition control signal. This feature can avoid
unnecessary battery drain that would otherwise occur if the inverter was
operated without a charging source such as the vehicle alternator. The
feature is standard on the Freedom HF platform.
To enable ignition control:
1. Ensure that AC and DC power are both OFF.
2. Ensure the vehicle’s ignition is turned to OFF position. It is highly
recommended to remove battery power by disconnecting the vehicle's
battery cables. Refer to the vehicle’s Owner’s Guide for proper
instructions on how to disconnect the battery cables.
3. Locate the vehicle's ignition control wire from the vehicle’s ignition
circuit. This wire must be fused appropriately at no more than
five amps. Refer to the vehicle’s Owner’s Guide for guidance.
4. Using a #1 Phillips screw driver, remove the screw securing the DC
wiring cover on the left hand side of the unit.
