Remote Emergency Power-Off - Eaton BladeUPS 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 example in the event of room overtemperature. When REPO is activated, the UPS
shuts down all converters, de-energizes all system relays, trips the UPS battery circuit breaker, and powers
down within 10–15 seconds. Note, however, that the unit continues to have logic power (display is still active)
and is not fully powered down until input power is disconnected from the unit.
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.
The REPO must not be connected to any utility connected circuits. Reinforced insulation to the
l
utility is required. The REPO switch must have a minimum rating of 24 Vdc and 20 mA and be a
dedicated latching-type switch not tied into any other circuit. The REPO signal must remain
active for at least 250 ms for proper operation.
To ensure that the UPS stops supplying power to the load during any mode of operation, the
l
input power must be disconnected from the UPS when the emergency power-off function is
activated.
Wire Function
REPO
There are two REPO positions that may be used, normally-open (NO) or normally-closed (NC). See Figure 71
on page 107 for REPO locations.
The pins on the NC 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 NC REPO
operation is desired, remove the jumper wire and connect an NC external switch. If the use of NO REPO
operation is desired, connect an NO external switch.
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. "

NOTE Leave the REPO connector installed in the REPO port on the UPS even if the REPO
function is not needed.
