Overview
Extended Runtime Modules
The UPS supports up to two ERMs (extended runtime modules). Each ERM consists of two
battery packs in a 4U chassis. When operating at the recommended 80 percent load, one ERM
will extend the available UPS runtime by up to 15 minutes.

Power Distribution Units
The UPS supports up to two PDUs. A PDU offers power surge protection and allows you to
distribute power among units.
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 to 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 will be
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 would normally initiate a battery start and
the UPS would assume the load. However, if the On button is pressed and a REPO is detected,
battery start is inhibited and the UPS will not be able to assume the load. The electronic module
fans will spin and the Alarm LED and an audible alarm will be active as long as the On button is
held.
