INSTALLATION

Remote Emergency Power-off Installation

The Powerware 9125 includes a REPO port that allows power to be switched off at the UPS output 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 reset, the equipment will not return to battery power until the UPS is manually restarted.

If the Off button is pressed after the REPO is activated, the UPS remains in Standby mode when restarted until the On button is pressed.

W A R N I N G

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.

C A U T I O N

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 open.

NOTE If the REPO function is not needed, the REPO connector must remain installed in the

REPO port on the UPS rear panel.

NOTE For Europe, the emergency switch requirements are detailed in Harmonized document HD-384-48 S1, “Electrical Installation of the Buildings, Part 4: Protection for Safety, Chapter 46: Isolation and Switching.”

To install the REPO switch:

1.Verify that the UPS is off and and disconnected from utility power.

2.Remove the REPO connector from the REPO port on the UPS rear panel.
