Battery Cable Connection

975-0209-01-01
WARNING: 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 2-5.
WARNING: Energy hazard
Connect and disconnect DC cabling only after opening the disconnect switches or
breakers at all AC and DC sources.
Observe battery polarity!
CAUTION: Reverse polarity damage
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 (–).
To connect the DC cables:
1. Route the DC cables from the battery bank to the inverter/charger.
2. If using a DC fuse and disconnect switch, connect the portion of the positive
DC cable that is to run between these two components. Use a wrench to
tighten the bolt to the torque recommended by the fuseholder or breaker
manufacturer.
3. Open the DC disconnect switch or turn off the DC circuit breaker.
4. Place the ring terminal of the POSITIVE (+) cable over the bolt and directly
against the inverter's battery terminal. Place a lock washer over the terminal.
Do not place the lock washer under the cable terminal. Figure 2-5.
Use a wrench to tighten the nut to a torque of 12 ft-lbs (16.3 Nm).
