Making AC Connections
This section describes how to make AC connections between the XW Inverter/Charger
and the XW Power Distribution Panel (using the pre-installed AC wiring in the XW Power
Distribution Panel) and between the XW Power Distribution Panel and the AC distribution
panel, or sub-panel (using wiring provided by the installer). See Appendix C, “Alternate
System Configurations” if the installation will not be including an XW Power Distribution
Panel.
Do not use a GFCI equipped AC source to power either the grid or generator inputs. The
AC input filters on the XW may cause nuisance tripping of ground fault protected outputs.
AC Connections and Communication Ports
AC Connections The AC terminal block includes three terminals each (L1, L2 and Neutral) for AC Grid
input, AC Generator input, and AC Load connections. The neutrals are connected to each
other, requiring only one neutral connection when installed with an XW Power
Distribution Panel. Without the XW Power Distribution Panel, additional neutral
connections may be required at the input sources.
Communication
Ports Four communications ports and one AUX Port are located on the bottom of the inverter
and support the following features.
•
The two AC sync ports are used for connecting multiple inverters in parallel.
• The two Xanbus ports are used for network connections between inverters, charge
controllers, and accessories.
• The AUX port provides 12 Vdc/250 mA output to control a relay, fan, indicator light
or other device. The auxiliary output can be configured (using a XW System Control
Panel) to trigger in response to low- or high-battery voltage or high- or low-battery
temperature. The auxiliary output can also be triggered manually using a XW System
Control Panel.

CAUTION: Damage to the Inverter
The inverter’s AC output must never be wired to the utility or generator output. This will cause
severe damage to the inverter which is not covered under warranty.
