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 battery circuit breaker, 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 60).
If the use of normally-open REPO operation is desired, connect a normally-open external switch (see
Figure 60).
NOTE 1 To restart the UPS, reconnect the REPO connector pins and turn on the UPS manually.
The pins must be shorted to keep the UPS running. Maximum resistance is 10 ohm
NOTE 2 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.

The UPS incorporates a programmable relay output with potential free contacts for remote alarm indications
(see Figure 60). An additional four relay outputs can be obtained with the X-Slot compatible Relay Interface
Card.
WARNING
The relay output contacts must not be connected to any utility connected circuits. Reinforced insulation to the
utility is required. The relay output contacts must have a maximum rating of 30 Vac/1A and 60 Vdc/2A nominal
values.

The UPS incorporates two programmable signal inputs (see Figure 60 on Figure 60). Use of non-polar (relay)
control input is recommended. The pins must be shorted with maximum resistance of 10 ohm in order to
activate the specific input.
