Connect Equipment
to the Back-UPS
The rear panel of the Back-UPS consists of the
following elements:
Battery Back Up Outlets (qty. of 3). These outlets
provide battery back-up, surge protection, and
Electro-magnetic Interference (EMI) filtering. In
case of power outage, battery power is automatically
provided to these outlets. Power (utility or battery) is
not supplied to these outlets when the Back-UPS is
switched Off. Connect a computer, monitor, and
external disk or CD-ROM drive to these outlets.
Surge Only Outlet. This outlet is always On (when
utility power is available) and is not controlled by
the On/Off switch. This outlet does not provide
power during a power outage. Connect a printer, fax
machine or scanner to this outlet.
Read the following reminders before installing the UPS.
• This UPS is intended for indoor use only.
• Connect the UPS power cable directly to a wall outlet. Do not use surge protectors or extension cords.
• When grounding cannot be verified, disconnect the equipment from the AC power outlet before installing
or connecting to other equipment. Reconnect the power cord after all connections are made.
• Servicing of batteries should be performed by Schneider Electric IT (SEIT) Customer Support only.
• When replacing battery the UPS must be OFF, and its AC inlet unplugged.
• Do not dispose of batteries in a fire. The batteries may explode.
• Do not open or mutilate batteries. They contain an electrolyte that is toxic and harmful to the skin and
eyes.
• To avoid harmful injury due to energy hazard, remove wrist watches and jewelry such as rings when
replacing the batteries. Use tools with insulated handles.
• Replace batteries with the same number and type of batteries as originally installed in the equipment.

Portable generator being used to
provide input voltage.
Disconnect non-essential equipment from the
Back-UPS. Reset the circuit breaker (located
on the rear panel of the Back-UPS) by pushing the circuit breaker button fully inward
until it catches. If the circuit breaker resets,
switch the Back-UPS on and reconnect the
equipment one-at-a-time. If the circuit
breaker trips again, it is likely that one of the
connected devices is causing the overload.
Check the wall outlet that supplies power to
the Back-UPS using a table lamp. If the lamp
bulb is very dim, have the utility voltage
checked by a qualified electrician.
Set the Transfer Voltage and Sensitivity
setting to Low (see Transfer Voltage and
Sensitivity Adjustment). By setting the BackUPS to Low sensitivity, it can accept a wider
range of input voltage.
Back-UPS does not power computer/monitor/external drive during an outage
Internal battery is not connected.
Computer, monitor or external disk/
CD-ROM drive is plugged into a
Surge Only outlet.

printers and plug them into Surge Only outlets.
Note: Devices that have motors or dimmer switches (laser printers,
heaters, fans, lamps, and vacuum cleaners, for example) should not be
connected to the Battery Backup outlets.
Charge the battery. The battery charges whenever the Back-UPS is
connected to a wall outlet. Typically, eight hours of charging time are
needed to fully charge the battery from total discharge. Back-UPS
run-time is reduced until the battery is fully charged.
Replace battery (see Order Replacement Battery). Batteries typically
last 3-6 years, shorter if subjected to frequent power outages or
elevated temperatures.
A red indicator is lit
