Initial Start-Up
To obtain warranty coverage, please fill out and
return the warranty registration card now.
Inspection
Inspect the UPS upon receipt. Notify the carrier and
dealer if there is damage. The packaging is
recyclable; save it for reuse or dispose of it properly.
Placement
Install the UPS in a protected area that is free of
excessive dust and has adequate air flow. Do not
operate the UPS where the temperature and humidity
is outside the specified limits.
Warning: Changes or modifications to this unit
not expressly approved by the party responsible
for compliance could void the warranty.
Connect to Utility
Full Time Surge Protected Outlet
The top-most white outlet provides surge
protection only. It is rated for 500VA (300W).
Equipment plugged into this outlet should require
surge protection, but should not require power
during a utility power failure. This could include a
laser printer, scanner, fax, or audio device.
Warning: The top outlet has voltage as long as the
UPS is connected to an active AC power source.
It has voltage even when the UPS is turned off.
Battery Power Supplied Outlets
The lower three outlets provide protection
from surges and battery backup protection.
Plug a computer, monitor, and other “data-
critical” devices into these outlets. Never plug a
laser printer into the Battery Power Supplied
outlets.
Connect the Loads
Plug the loads into the output connectors on the rear
of the UPS. To use the UPS as a master on/off
switch, make sure that all of the loads are switched
on.
Connect Telephone Surge Suppression
(Optional)
Connect a single line telephone cable from
the telephone jack into the RJ-11 telephone surge
protection IN jack on the back of the UPS.
Connect from the OUT jack to the computer
with telephone cable.
Connect Computer Interface
Port (Optional)
PowerChute® plus power management software is
included with this UPS. Connect the supplied
interface cable to the 9-pin computer interface port
on the back panel of the UPS. Connect the other end
to a dedicated serial port on your computer. See
software documentation for installation instructions.
Charge the battery
The UPS charges its battery whenever it is
connected to utility power. The battery will charge
fully during the first 4 hours of normal operation.
Do not expect full runtime during this initial charge
period.
Operating Instructions
Switch On — Switch Off
With the UPS plugged in, press and release
the on/off/test button to supply power to the
loads plugged into the Battery Power Supplied
outlets. The equipment plugged into the Full Time
Surge Protected outlet (the top outlet) has power
whenever the UPS is connected to an active AC
power source.
The Battery Power Supplied loads are immediately
powered while the UPS performs a self-test. Press
and release the button again to turn off power to the
loads. It may be convenient to use the UPS as a
master on/off switch for the protected equipment.
The on-line LED illuminates when the UPS
is supplying utility power to the loads.
Self-test
The UPS performs a self-test automatically when
turned on, and every two weeks thereafter (by
default). Automatic self-test eases maintenance
requirements by eliminating the need for periodic
manual self-tests.
During the self-test, the UPS briefly operates the
loads on-battery. If the UPS passes the self-test, it
returns to on-line operation.
If the UPS fails the self-test it immediately
returns to on-line operation and lights the
replace battery LED.
The loads are not affected by a failed test. Recharge
the battery overnight and perform the self-test again.
If the replace battery LED is still on, replace the
battery using the Replacing the Battery procedure.
On Battery
During on-battery operation, the on-battery
LED illuminates and the UPS sounds an
audible alarm consisting of 4 beeps every 30
seconds. The alarm stops when the UPS returns to
on-line operation. The alarm may also be disabled
using PowerChute® plus power management
software.
Low Battery
When the UPS is operating on-battery and the
energy reserve of the battery runs low, the UPS beeps
continuously until the UPS shuts down from battery
exhaustion or returns to on-line operation.
Overload
When loads exceed the UPS’s capacity, the
overload LED illuminates and the UPS
emits a sustained tone. The alarm remains
on until the overload is removed. Disconnect
nonessential load equipment from the UPS to
eliminate the overload.
If the overload is severe, the input circuit breaker
may trip (the resettable center plunger of the circuit
breaker pops out). Disconnect nonessential load
equipment from the UPS to eliminate the overload
and press the plunger back in.
If there is AC power and the circuit breaker does not
trip during overload, the loads are still powered. If
the circuit breaker trips or the UPS attempts to
transfer to battery, the loads’ power will be shut off.
Turn the UPS off then back on to power the loads.
Replace Battery
If the battery fails a self-test, the UPS emits short
beeps for one minute and the replace battery LED
illuminates.
The UPS repeats the alarm every five hours. Perform
the self-test procedure to confirm replace battery
conditions. The alarm stops when the battery passes
the self-test.
Shutdown Mode
If there is no power, the host connected to the
computer interface port can command the UPS to
shut down. This is normally done to preserve battery
capacity after a controlled shutdown of the protected
system. In shutdown mode the UPS stops supplying
power to the load. The online and overload LED
indicators flash alternately or, if the UPS has
shutdown due to a low battery, the UPS will beep
once every 4 seconds for approximately 16 seconds.
When line power is restored, the UPS will return to
on-line operation.
Cold Start
Note: Cold start is not a normal operating
condition.
When the UPS is off and there is no utility power, it
is possible to cold start the UPS to power the loads
from the UPS’s battery.
• Press and hold the on/off/test button
until the UPS begins beeping.
• Release the on/off/test button during the beeping to
start the UPS.
Storage
Storage Conditions
Store the UPS covered and upright in a cool, dry location, with its battery fully
charged. Before storing, charge the UPS for at least 4 hours. Disconnect any cables
connected to the computer interface port to avoid unnecessarily draining the battery.
Extended storage
At -15 to +30 °C (+5 to +86 °F), charge the UPS’s battery every 6 months
At +30 to +45 °C (+86 to +113 °F), charge the UPS’s battery every 3 months.
