Remote Emergency Power-Off

The Powerware 5125 includes a REPO port that allows power to be
switched off at the UPS output receptacles from a customer-supplied
switch in a remote location.
The REPO feature shuts down the protected equipment immediately and
does not follow the orderly shutdown procedure initiated by any power
management software.
Any devices that are operating on battery power are also shut down
immediately. When the REPO switch is re-opened, the equipment will
not return to battery power until the UPS is manually restarted.
If the Off
remains in Standby mode when restarted until the On button is
pressed.
The REPO circuit is an IEC 60950 safety extra low voltage (SELV) circuit. This circuit
must be separated from any hazardous voltage circuits by reinforced insulation.
To ensure the UPS stops supplying power to the load during any mode of operation,
the input power must be disconnected from the UPS when the emergency power-off
function is activated.
NOTE The REPO function activates when the REPO contacts close.
Use the following procedure to install the REPO switch:
1. Verify that the UPS is off and unplugged.
2. Locate the REPO connector from the P33 accessory kit.
3. Connect isolated, normally-open, dry contacts (rated at 60 Vdc
