Eaton BladeUPS - Installing REPO for a Standalone UPS

114 Eaton BladeUPS 5 kVA to 60 kVA (N+1) User’s Guide 164201649—Rev 14
WARNING
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.
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 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 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 78 on
page 114 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.

To install a REPO switch for a standalone UPS:
1. Verify that the UPS is turned off and all power sources are removed. See section 5.11” Standalone UPS
Shutdown” 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.
3. Connect the appropriate external switch to the selected REPO contact. See Figure 79 for NO REPO wiring
and Figure 80 for NC REPO wiring.
4. Reconnect the REPO connector pins and turn on the UPS manually to restart. The pins must be shorted to
keep the UPS running. Maximum resistance is 10 ohm.
