Remote Emergency Power-Off
The Powerware 9120 includes a REPO port that allows power to be
switched off at the UPS output connections from a customer-supplied
switch in a remote location.
The REPO feature shuts down the protected equipment immediately,
whether or not the UPS is in Normal or Battery mode, and does not
follow the orderly shutdown procedure initiated by any power
management software. The UPS switches to Standby mode.
When the external REPO switch is re-closed, the UPS must be manually
restarted to provide power to the connected equipment.
If the
button is pressed after the REPO is activated, the UPS remains
in Standby mode when restarted until the
button is pressed again.
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.
