UPS, it will immediately begin a self test to
determine if an overload situation exists.
If it detects an overload, an audible alarm
will sound. You will hear a long beep before
the system automatically shuts down. If
this occurs:
Unplug at least one piece of equip-
ment from the battery back-up outlets.
Turn off the power to the UPS.
Wait 5 seconds.
Make sure the circuit breaker is set.
Turn the UPS back on.
Note
Your UPS is equipped with a self protec-
tion feature that prevents accidental
damage if the UPS is turned on and off
repeatedly. Once you turn your UPS off,
you must wait 5 seconds before turning it
on again.
Philips recommends you perform a simula-
tion test when using your UPS for the first
time or when connecting an additional
piece of equipment.
To conduct a simulation test:
Turn on the UPS.
Wait for the power indicator to
illuminate.
Unplug the UPS power cord from the
wall. This simulates a power failure.
When an electrical power failure occurs,
the battery power outlets of your UPS will
supply power to the connected equipment
from its battery. An alarm will beep once
every two seconds.
4. Confirm all equipment connected to
the battery power outlets of your UPS is
operating under the limited rating power.
5. Restore power to UPS by plug the
power cord back into the wall outlet.
Repeat this simulation test a few times to
confirm your UPS is working properly and
determine the expected runtime.
Note
If a power failure occurs immediately
after you turn on the UPS, but before its
initial self-test sequence, your UPS will
automatically shut down. It will not restart
until electrical power is restored. This al-
lows your UPS to check the quality of the
power that is delivered to your connected
equipment.
Tip
To maintain a full battery charge, leave
your UPS plugged in and turned on at all
times.
The surge protection of your UPS has a
limited life. Even under normal circum-
stances, and in the absence of defects,
this surge protection will end when the
components providing protection exceed
capacity and cease to provide protection
from power surges and spikes.
These surge protection components
feature an internal protection that will
disconnect them at the end of their useful
life, but will still maintain power to your
connected equipment (load). When this
occurs, you will have to replace your UPS
to restore protection to your connected
equipment.
