Remote Emergency Power-Off - Eaton 9355-F47 Unirom User Manual

Remote Emergency Power-off

REPO is used to shut down the UPS from a distance. This feature can
be used for shutting down the load and the UPS by thermal relay, for
instance in the event of room overtemperature. When REPO is
activated, the UPS shuts down all converters; de-energizes all system
relays; trips the input, output, and battery circuit breakers; and fully
powers down within 10-15 seconds.
Two REPO switches may be used; they should have normally-closed
contacts.
NOTE To restart the UPS, reset the REPO switches and turn on the UPS manually. The
switches must be closed to keep the UPS running. Maximum resistance is 10 ohm.
S
The REPO must not be connected to any utility connected circuits. Reinforced insulation
to the utility is required. The REPO switch must have a minimum rating of 24 Vdc and
20 mA.
S
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.
