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, and fully powers down within 10-15 seconds.
There are two REPO positions that may be used, normally-open or
normally-closed.
The pins on the normally -closed REPO connector are connected
together. When this connection is open, the logic circuitry completely
shuts down the UPS, thus preventing the power from supplying the
load.
If the use of normally-closed REPO operation is desired, replace the
connector with a normally-closed external switch (see Figure 33 on
page 47).
If the use of normally-open REPO operation is desired, connect a
normally-open external switch (see Figure 33 on page 47).
NOTE To restart the UPS, reconnect the REPO connector p ins and turn on the UPS
manually. The pins must be shorted to keep the UPS running. Maximum resistance is 10 ohm.
NOTE Leave the REPO connector installed in the REPO port on the UPS rear panel even if
the REPO function is not needed.
CAUTION
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.
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.
