Remote Emergency Power-Off - Eaton 9130 Guia De Instalacion

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
instance in the event of room overtemperature. When REPO is
activated, the UPS shuts down the output and all its power converters
immediately. The UPS remains on to alarm the fault.
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 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."
