WARNING
DANGER OF BATTERY EXPLOSION – INSTALL A FUSE
Battery banks can deliver very high levels of current that can vaporize metal, start fires and cause explosions.
HARDKORR recommends installing a ANL fuse and fuse holder (supplied with your purchase) as close to the
positive battery bank terminal as possible. This fuse protects the batteries from accidental DC cable shorts,
which can cause batteries to explode.
MOUNTING INSTRUCTIONS
Your HARDKORR Inverter should not be mounted under the hood of a vehicle. If installing in a vehicle, choose a
dry, cool, ventilated area closest to the battery as practical. Before drilling any mounting holes, make sure that-
there are no wires, fuel lines, or tanks directly behind the surface to be drilled.
To mount the inverter:
1. Inverter must be OFF.
2. Position the inverter against the mounting surface and mark locations of the mounting screw openings.
3. Remove the inverter and drill four mounting holes.
4. Fasten the inverter to the mounting surface using corrosion-resistant fasteners sized M6 or larger.
CONNECTING INVERTER
1. Prepare all cable ends with cable lugs.
2. Install a circuit breaker or high current fuse in the positive line as close to the battery as possible.
3. Make sure the inverter is turned OFF.
4. Connect the cables to the DC input terminals on the rear of the inverter. The red terminal is positive (+)
and the black terminal is negative (-).
4. Connect the positive cable to the inverter and battery positive terminals.
5. Connect the negative cable to the inverter and battery negative terminals.
6. Connect an insulated wired from the chassis-ground terminal at the front panel of the inverter to the
vehicle’s chassis or any other ground point.
OPERATION
1. Turn OFF the inverter.
2. Plug an appliance cord into the front panel of the inverter.
3. Turn ON the inverter.
4. Turn the appliance on.
5. Plug in additional appliances and turn them on.
LED LIGHT INDICATIONS
HARDKORR inverters are equipped with two status LED’s and audible alarm. During normal operation, the green
LED will illuminate solid green. In the event of a fault or error, the alarm will sound and a red LED will illuminate.
NOTE: Sparking is normal for the first connection. Make sure you have good secure connections – But do not over-tighten.
