Make sure that all AC and DC breakers are switched off before connecting or
disconnecting the battery cables, and make sure that all sources of power (both
AC and DC) are disconnected from the inverter.

To connect DC cables to the Xantrex XW Inverter/Charger:
1. Route the DC cables from the battery bank to the inverter/charger.
2. Install a DC fuse and disconnect switch or a DC circuit breaker between the
inverter/charger and the battery. They must be installed in the positive side of
the DC circuit, as close as possible to the battery. See Figure 2-9, "Xantrex
XW Inverter/Charger DC Connections" on page 2–16.
This protects your battery and wiring in case of accidental shorting. Before
proceeding, make sure the DC disconnect switch is open or that the DC
circuit breaker is turned off.
3. Connect one connector on the POSITIVE (+) cable to the POSITIVE DC
terminal on the inverter/charger. Be careful to observe proper polarity. Figure
2-10 shows the proper stacking order of hardware. Use a wrench to tighten
the bolt to the required torque.
4. Connect the other connector to the POSITIVE (+) terminal on the fuse or
breaker. Observe polarity carefully while completing the installation.
Follow the fuseholder or breaker manufacturer's torque recommendation.
5. Connect the NEGATIVE (–) battery cable to the NEGATIVE (–) DC terminal on
the inverter/charger. Be careful to observe proper polarity. Figure 2-10 shows
the proper stacking order of hardware. Use a wrench to tighten the bolt to the
required torque.
6. Before proceeding, check that the cable polarity is correct: POSITIVE (+) on
the inverter/charger is connected to the POSITIVE (+) on the battery and the
NEGATIVE (–) cable is connected to the NEGATIVE (–) terminal on the
inverter/charger.
