Installation

4. Install a fuse and disconnect switch or breaker between the inverter
and the battery. Ensure that the disconnect switch or breaker is turned
off before installing. They 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 shorting. See “Calculating
Fuse/Circuit Breaker Size” on page 3–7.
5. Attach one connector on the positive cable to the positive DC
terminal on the DC end, and then attach the other connector to the
POSITIVE (+) terminal on the fuse or breaker.
Observe the polarities carefully while completing the installation. Use
a wrench to tighten to a torque of 216–240 inch-pounds (24–27 Nm).
Test that the cable is secure.
CAUTION: Reverse polarity
DC power connections to the inverter must be positive to positive and negative to
negative. A reverse polarity connection (positive to negative) will blow a fuse in
the inverter and may permanently damage the inverter. The fuse is not user
replaceable and the inverter may need to be returned for servicing.
Damage caused by a reverse polarity connection is not covered by your warranty.
CAUTION
Do not over-tighten the nut on the DC input terminals. Damage to the DC input
terminals may result.
CAUTION
Do not remove the terminal nut.
CAUTION
Loose connections cause excessive voltage drop and may cause overheated wires
and melted insulation.
