Xantrex Technology Freedom SW 2000 Connecting the DC Cables to the Inverter/Charger, Fire Hazard

Installing the Inverter/Charger

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 10–11 ft-lbs (13.6–14.9 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 3.

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.

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 25.

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 shorting. See Table 3 on page 11 for required fuse or breaker size.

3.Open the DC disconnect switch or turn off the DC circuit breaker.

4.Connect one connector on the POSITIVE (+) cable to the POSITIVE DC terminal on the inverter/charger, as shown in Figure 3. The connector goes on first, then the flat washer (steel), lock washer (steel), and nut 5/16” (steel).

5.Connect the other connector to the POSITIVE (+) terminal on the fuse or breaker. Observe polarity carefully while completing the installation.

Use a wrench to tighten the nut to a torque of 10–11 ft-lbs (13.6– 14.9 Nm) at the inverter/charger end. Observe the fuseholder or breaker manufacturer’s recommendation at the other end.

6.Connect one connector on the NEGATIVE (–) cable to the NEGATIVE (–) DC terminal on the inverter/charger, as shown in Figure 3. The connector goes on first, then the flat washer (steel), and nut 5/16” (steel).
