Fusing Requirements
NOTE: It is important that for this 3000 watt inverter has two ANL 300 ampere or
equivalent main battery fuses be added to the positive (+) battery cable as close as possible
to the battery bank’s positive terminal. The fuse amperage rating must be sized to allow
simultaneous operation of all the AC appliances to be powered, allowing for the momentary
high startup current requirements of inductive loads. Use the recommended fuse block (fuse
holder) and fuse, or an electrical equivalent. ANL type fuses and fuse holders are readily
available from marine supply dealers.
The fuses are very important to protect equipment, batteries and personnel. The fuses protect
against battery explosion if the cables that connect to the inverter accidentally short.
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 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.
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.
Procedure
Make sure the cables are the proper gage and have the fuse holders as close to the
battery bank’s Positive (+) terminal.
Install the fuses in the Positive (+) cables.
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.
