Remote Emergency Power Off Port
The UPS includes an isolated REPO port. When properly wired, the REPO feature allows the
power at the UPS output receptacles to be switched off from a remote location. To use this
feature, the REPO port must be connected to a remote, normally open switch (not supplied).
When this switch is closed, the UPS immediately disconnects power from its loads. The
REPO switch is used in conjunction with a main disconnect device that removes the AC
source from the input of the UPS. To power down the entire network in the event of an
emergency, the REPO ports of multiple UPS units can be connected to a single switch.
IMPORTANT:
• The REPO port meets the requirements of NFPA Articles 645-10 and 645-11 for a Disconnecting
Means.
• If the remote switch is closed, the REPO feature immediately powers down protected devices and
does not utilize the orderly shutdown procedure initiated by power management software.
• The REPO feature shuts down UPS units operating under either utility or battery power.
• If the UPS was operating on battery power when the remote switch was closed, no power is
available to the devices until utility power is restored and the UPS has been manually powered up.
• To restore power to the load after the REPO feature is activated, press the On button after the AC
source is reconnected to the UPS.
• Pressing and holding the On button without utility present normally initiates a battery start and the
UPS assumes the load. However, if the On button is pressed and a REPO is detected, battery start
is inhibited and the UPS is not able to assume the load. The electronic module fans spin and the
Alarm LED and an audible alarm are active as long as the On button is held.
