Auxiliary (AUX) Port
The auxiliary output is designed to provide the following functions:
• Auxiliary 12 VDC power supply
• Remote power off
The auxiliary 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
Xantrex XW System Control Panel) to trigger in response to:
• low battery voltage
• high battery voltage
• low battery temperature
• high battery temperature
• any device fault
The auxiliary output can also be triggered manually using the Xantrex XW System
Control Panel.
The 12 VDC output can trigger a relay to disconnect batteries from the inverter/
charger when battery voltage or temperature are out of the ideal range.
AUX+12V Voltage Supply
DC voltage is available between JU-1 (AUX +12 V) and JU-3 (AUX-COM, signal
return). The power available at these terminals is 12 VDC, and maximum current
is 250 mA (3 watts).
The AUX+12 V and AUX-COM terminals can be used to power a relay (3 watts
maximum). Additional fuses are not required, but may be required for some
installations. The default status of AUX+12 V is O
