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) provides the system shut off function if
the switch is closed.
The external switch, if pressed, overrides the control provided from the front
panel.
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 system
designer or qualified technician for specific installation instructions.
