Connecting to an External Battery
445-0127-01-01 2–21
The cable and connectors specified above are typically available at RV,
marine, or auto parts stores. When possible, we recommend purchasing
one length of cable with red insulation and the other length of cable with
black insulation. Use the red cable length to connect the positive
terminals and the black length of cable to connect the negative terminals.
Connecting the Cables
Position the external battery on a stable and level surface close to XPower
1500. Then follow these steps to connect the cables from the external
battery to XPower 1500:
1. Remove XPower 1500’s Terminal Covers (rotate counter clockwise)
and place them in the unit’s Accessory Storage Compartment.
2. If you have one red cable and one black cable, attach the end of the
red cable with the battery terminal connector to the positive (+)
terminal of the external battery. If both cables are the same color, use
red tape or another method to clearly mark which cable is positive
and which cable is negative.
3. Use the red Terminal Cover to fasten the 5/16” ring type connector on
the other end of the positive cable (red or marked positive) to XPower
1500’s positive (+) High Power DC Terminal (red). Tighten the
terminal cover firmly by hand, but do not over tighten.
4. Attach the end of the second cable (black or marked negative) with
the battery terminal connector to the negative (-) terminal of the
external battery.
WARNING: Fire hazard
Do not connect an external battery to XPower 1500 using automotive jump-start
cables or any other type of cables that are designed for making a temporary
connection. These types of cables will not provide the secure connection required
when operating AC products with high power requirements and their use can
create a fire hazard.
WARNING: Shock or fire hazard
Connect only in the following order and make sure the polarity is correct. The
external battery’s positive terminal may be identified with a (+) or may be larger
in diameter than the negative terminal. The negative terminal may be identified
with a (-). Do not connect any cables until you are sure you have identified the
positive terminal.
