User’s Manual—Read before using this equipment

READ AND COMPLY WITH THE WARNING BELOW
EXPLODING BATTERIES CAN SPRAY MOLTEN LEAD, HOT SULFURIC ACID AND OTHER METAL
AND PLASTIC FRAGMENTS. BATTERIES THAT ARE CHARGING OR UNDER HIGH DISCHARGE
RATES PRODUCE EXPLOSIVE HYDROGEN GAS INTO THE SURROUNDING AREA. BE SAFE–
FUSE THE BATTERY BANK AND MAKE SURE THE BATTERIES ARE PROPERLY VENTILATED.
DC Cable Gage
Minimize cable losses by using the thickest wire available, and the shortest practical length.
If the inverter and the battery are positioned within four feet of each other, a minimum of
0 gage (zero gage) insulated copper wire should be used to make the connections. If the
distance is longer than 4 feet, heavier wire will be required. If insulated aluminum wire is
used instead of copper wire, 00 gage is a substitute for 0 gage copper wire.

The diagram below shows inverter connections to a battery bank with recommended fuse
protection.
CONNECTING THE INVERTER
General information
Loose connections will result in a severe voltage drop that can cause damage to connectors,
conductors and insulation and can cause sparking. Reverse polarity connection will blow
the fuses in the inverter and can permanently damage to the inverter. Damage caused by
reverse polarity will void the warranty.
There are two sets of DC input terminals to ease cable connections and reduce the need for
larger gage cables. For AC loads less than 2,500 watts only one set of cables is required.
For loads over 2,500 watts use two sets.
Procedure
1. Make sure the cables are the proper gage and have the fuse holders as close to the
battery bank’s positive (+) terminal.
2. Install the fuses in the positive (+) cables.
3. Make sure the ON/OFF switch located on the front panel of the inverter is in the
OFF (0) position. Disconnect any remote switch from the connector on the front
panel.
4. Locate the ground lug terminal at the rear of the inverter. Connect an insulated 6
gage copper wire to the terminal. The other end of the ground wire is connected to
a “proper” grounding point. Use the shortest practical length of wire. Connect this
wire to the chassis of your vehicle or to the grounding system in your boat. In a city,
the ground wire can connect to a metal cold water pipe that goes underground. In
remote locations, the ground wire can be connected to an “earth ground”. This can
be an attachment to a 6 foot long copper clad metal rod driven into the ground. In
the unlikely event of a short circuit, operating the inverter without proper grounding
can result in electrical shock. Do not directly connect this ground wire to the
negative (−) DC Terminal.
5. NOTE: Crimp-on ring terminals are required on all cable ends. The cable ends
need to be stripped of insulation for approximately 5/16th of an inch before
crimping ring terminals. Select ring terminal size to fit the gage cable and inverter
and battery terminal diameters. After crimping make sure that the cable connectors
are secure on the cables so there are no loose connections.
6. Use a medium blade common screwdriver and loosen the cable connector screw.
Insert the negative (−) cable end into the terminal. Tighten the screw to clamp the
cable end. Make sure you have a good, secure connection.
7. Recheck and make sure the DC cable fuses are installed in the fuse holders.
CAUTION: Making an initial connection between the positive cable and the
inverter’s positive terminal may cause a spark. This is a normal and is a result of
capacitors in the inverter starting to charge. Because of the possibility of sparking,
it is extremely important that both the inverter and the battery bank be positioned
away from any source of flammable fumes or gases. Failure to heed this warning
