Remote Emergency Power-Off Installation - Eaton Powerware 9125 User Manual

Remote Emergency Power-off Installation

The Powerware 9125 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 reset, 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.
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."
