Conext XW Pro Installation Guide

The 12VDC output can be used to trigger an HBX (Hi Battery Transfer) relay to
disconnect from the Grid.
The auxiliary output is also designed to provide the following functions:
n Auxiliary 12VDC power supply. See AUX+12V Voltage Supply, below.
n Remote Power Off. See AUX-RPO: User Remote Power OFF (RPO), below.
Figure 24 AUX Port Location
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 (maximum 3 watts).
Note: Additional fuses may be necessary for some installations.
AUX +12 V voltage supply can be programmed for different tasks ON and OFF using the
Conext Gateway.
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 (normally 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 Remote Power Off setting
from the Conext Gateway. For more information, see the Owner's Guide. If the external
switch is cleared (notpressed), the inverter can be enabled back from the front panel.
NOTE: The Conext MPPT60 or MPPT80 will require a power cycle to recover.
Select an external switch with normally open contact; consult your local system designer
or qualified technician for specific installation instructions.
User Line Wiring
Use twisted pairs of #24 AWG to #12 AWG for connections. Carefully route the wires
away from high power load cables to minimize noise effects on signal integrity.
