26 Freedom SW 2000 Installation Guide
Installing the Inverter/Charger
Connecting the DC Cables to 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 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).
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.
