Remote Emergency Power-Off; Installing Repo For A Standalone Ups - Eaton Powerware 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.
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 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.
S
To ensure that 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 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.
There are two REPO positions that may be used, normally-open (NO) or
normally-closed (NC). See Figure 73 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.

Installing REPO for a Standalone UPS

To install a REPO switch for a standalone UPS:
1. Verify that the UPS is turned off and all power sources are removed. See
"Standalone UPS Shutdown" on page 102 for shutdown instructions.
2. Securely mount the remote REPO switch. Recommended locations include near
operator's consoles or near exit doors. Refer to the REPO switch manufacturer's
installation instructions for enclosure dimensions and wiring knockouts.
