Connecting the DC Cables to the Inverter/Charger

FIRE HAZARD

Use only appropriately sized copper cable. Loose connections or improper connections will overheat. Make sure the bolts supplied by Xantrex on the inverter/charger are tightened to a torque of 15–16 ft-lbs (20.4–21.7 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 Figure 5.

Failure to follow these instructions will result in death or serious injury.

EQUIPMENT DAMAGE DUE TO REVERSE POLARITY

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 (–).

Failure to follow these instructions can damage the unit and/or damage other equipment.

Installing the Inverter/Charger

To connect the DC cables:

1.

Route the DC cables from the battery bank to the inverter/charger.

 

 

Observe the “Guidelines for Routing the DC Cables” on page 28.

 

2.

Install a DC fuse and disconnect switch or a DC circuit breaker
