This manual is for use by qualified personnel only
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 range.
The auxiliary output is also designed to provide the following functions:
• Auxiliary 12 VDC power supply. See AUX+12V Voltage Supply, below.
• Remote Power Off. See AUX-RPO: User Remote Power OFF (RPO), below.
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).
AUX+12 V and AUX-COM terminals can be used to power a relay
(3 watts maximum).
AUX +12 V voltage supply can be programmed for different tasks ON and OFF
using the Conext System Control Panel.
Default status of AUX+12 V is OFF.
AUX-RPO: User Remote Power OFF (RPO)
Connecting JU-2 (AUX-RPO) and JU-3 (AUX-COM) terminals together through
an external switch (normal open contact) will provide the system shut off function
if the switch is closed. The external switch, if pressed, overrides the control
provided from the front panel.
To enable the AUX port remote power off function, enable the RPO setting from
the System Control Panel. For more information, see the
Conext XW+ Inverter/
Charger Owner’s Guide. If the external switch is cleared (not pressed), the
system can be enabled back from the front panel.
Select an external switch with normal open contact; consult your local system
designer or qualified technician for specific installation instructions.
