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.

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.

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

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.
