front of the unit, or follow the steps under Replacing
the Battery Pack, below.
Placement
Warning! Changes or modifications to this unit
not expressly approved by the party responsible

Rack Mounting
The UPS comes with standard 19" (46.5 cm) rack
mount brackets. It is supplied with four (4) screws to
attach the mounting brackets (ears) to the chassis.
Select a rack location with adequate air flow that is
free from excessive dust. Ensure that the air vents on
the sides of the UPS are not blocked. Do not operate
the UPS where temperature or humidity are outside
the limits in the Specifications section of this manual.

I/O
With the UPS plugged in, press and release the
on/off/test button to supply power to the loads.
The 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 green 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. Automatic
self-test eases maintenance requirements by
eliminating the need for periodic manual self-tests.
During the self-test, the UPS briefly powers the loads
on-battery. If the UPS passes the self-test, it returns
to on-line operation.
If the UPS turns off during the self-test and emits a
fading tone, the batteries are not connected properly.
Storage
Storage Conditions
Before storing, charge the UPS for at least 8 hours. Cover the UPS and store it lying
flat in a cool, dry location, with its battery pack fully charged.

On Battery
During on-battery operation, the yellow 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.
Low Battery
When the UPS is operating on-battery and the energy
reserve of the battery pack runs low, the UPS beeps
continuously until the UPS shuts down from battery
pack exhaustion or returns to on-line operation, if the
utility power returns before the battery pack is
exhausted..
Replace Battery
If the battery pack fails a self-test, the UPS emits
short beeps for one minute and the red 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 pack
passes the self-test.

hazard.
Connect the Battery Pack
The UPS is shipped with the battery pack
disconnected. To connect the battery pack, follow
the procedure in Replacing the Battery Pack, below.
The UPS charges its battery pack whenever it is
connected to utility power. The battery pack will
charge fully during the first 4 hours of normal
operation. Do not expect full battery back-up
runtime during this initial charge period.
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 pack.

Overload
When loads exceed the UPS's capacity, the red
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.
