Guidelines for Routing the DC Cables
Follow these guidelines to ensure maximum performance.
DANGER
ELECTRICAL SHOCK AND FIRE DAMAGE
n
Route the cables away from sharp edges that might damage
the insulation. Avoid sharp bends in the cable.
n
Do not attempt to use the chassis in place of the battery
negative connection for grounding. The inverter requires a
reliable return path directly to the battery.
n
To reduce the chance of radio frequency interference, keep
the positive and negative cables close together—ideally,
held together by straps, loom, or insulated clamps at regular
intervals.
n
To ensure maximum performance from the inverter/charger,
do not route your DC cables through a DC distribution panel,
battery isolator, or other device that will cause additional
voltage drops. The exception is the DC fuse and Disconnect
or the DC circuit breaker which is required at the battery to
protect the DC wiring.
n
To help avoid damage caused by reverse polarity battery
connection, it is a good idea to mark each end of each cable
to identify it as a positive (red) or negative (black) cable
before routing the wiring.
Failure to follow these instructions can damage the unit and/or
damage other equipment.
Connecting the DC Cables to the
Inverter/Charger
WARNING
FIRE HAZARD
Use only appropriately sized copper cable. Loose connections,
improper connections, and under-rated cables will overheat. Make
sure that the supplied bolts on the inverter/charger are tightened to
a torque of 11–12 ft-lbs or 132–144 inch-lbs or 14.9–16.3 Nm.
Torque all other connections to the manufacturer’s specifications.
Make sure the DC cable, washers, and bolt are assembled in the
order shown in
.
Failure to follow these instructions can result in equipment
damage.
Before making the final DC connection or closing the DC breaker
or disconnect, check cable polarity at both the battery and the
inverter/charger. Positive (+) must be connected to positive (+).
Negative (–) must be connected to negative (–).
To connect the DC cables:
1. Route the DC cables from the battery bank to the
inverter/charger. Observe the guidelines in
.
2. Install a DC fuse and disconnect switch or a DC circuit
breaker between the inverter/charger and the battery. It
must be installed in the positive side of the DC circuit, as
close as possible to the battery.
This protects your battery and wiring in case of accidental
