The REPO/ROO circuit is an IEC 60950 safety extra low voltage (SELV) circuit. This circuit
must be separated from any hazardous voltage circuits by reinforced insulation.
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.
NOTE The REPO function activates when the REPO contacts close.
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."
For more information about how the REPO and ROO features function,
see "Remote Emergency Power-off and Remote On/Off" on page 70.
To install the REPO or ROO switch:
1. Verify that the UPS is off and disconnected from utility power.
2. Insert the REPO connector (provided in the accessory kit) into the
REPO port on the UPS rear panel. See Figure 38 on page 69 for the
location of the REPO port.
