AUX-RPO: User Remote Power Off (RPO)

User Line Wiring

AUX Port Terminal Assignments

975-0239-01-01
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, the RPO setting must be enabled from
the System Control Panel. For more information, see the XW Inverter/Charger Operation
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.
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.
