REPO and ROO Installation
The Eaton 9140 includes a two-position terminal (see Figure 35) that can
be either left open or configured one of two ways:
S
As a remote emergency power-off (REPO) contact
that allows power to be
switched off at the UPS output from a customer-supplied switch in a
remote location.
S
As a remote on/off (ROO) contact
that allows the UPS to be turned on
and off from a customer-supplied switch in a remote location.

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
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 76.
