Inverter/Charger Installation

Making DC Connections

This section describes how to make DC connections between the inverter/charger and the power distribution panel (using the pre-installed DC cables in the distribution panel), between the distribution panel to the batteries (using battery cables provided by the installer—see Table 2-2 on page 2–10). This section also provides procedures for installing the battery temperature sensor. See Appendix C, “Alternate System Configurations” if the installation will not be including an XW Power Distribution Panel.

WARNING: Shock Hazard

Ensure that all AC and DC breakers are switched OFF before connecting or disconnecting the battery cables and that all sources of power (both AC and DC) are disconnected from the inverter.

To connect the XW Power Distribution Panel to the inverter:

1.Connect the pre-installed DC cables from the XW Power Distribution Panel to the inverter DC terminals. Figure 2-10 shows the proper stacking order of hardware. Be careful to observe proper polarity.

2.Attach the DC terminal covers.

3.Route the DC cables from the battery—with the cables not connected to the battery— and connect them to the XW Power Distribution Panel: negative to negative bus, positive to the input end of the DC breaker. To properly attach and torque the positive cable to the DC breaker, you may need to temporarily remove the breaker from the rail.

4.Perform the procedures in “Making AC Connections” before connecting the DC cables from the XW Power Distribution Panel to the battery.
