The XW Series has a 12 Vdc auxiliary output that can be configured to trigger in response
to one of the following battery conditions:
• low battery voltage
• high battery voltage
• low battery temperature
• high battery temperature
• any device fault
The auxiliary output can also be triggered manually.
The 12 Vdc output can be used to trigger a relay to disconnect batteries from the inverter/
charger when battery voltage or temperature are out of the ideal range.
The auxiliary output is designed to provide the following functions:
• Auxiliary 12 Vdc power supply
• Remote Power Off
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 0.25 Adc
(3 watts).
