• CHARGE ONLY Mode: DISABLES battery backup. UPS
Conditions: The UPS charges its battery and supplies power at its
receptacles when it is receiving utility line power. The "
tor light is flashing. Setting Advantages: Continues to charge the bat-
tery when power is present while turning OFF the inverter to prevent
battery depletion during power outages when equipment is not in use.
Cold-Start Your UPS: You may "cold start" your UPS and use it as a
stand-alone power source when utility power is not present, providing
that the UPS battery is charged. To "cold start" your UPS, press and
hold the ON/OFF button until you hear a beep (about 2 seconds), then
release it. The " " indicator light will illuminate and AC power
inverted from stored battery power will be provided at its receptacles.
Shut Down Your UPS: Press and hold the ON/OFF button when AC
line power is absent (i.e. during a blackout, or when the UPS is
unplugged) to deactivate your UPS.
Silence the UPS On-Battery Alarm: Press and hold this button to
silence the UPS On-Battery alarm, a series of short beeps followed by
a brief pause that is activated when the UPS is providing AC power
from battery. Note: When the battery is nearly depleted, the Low
Battery alarm—a continuous beep that cannot be silenced—will alert
you to immediately shut down connected equipment.
Run a Self-Test: To start a self-test, leave your connected equipment
on. With your UPS plugged in and in the UPS mode, press and hold this
button until you hear a beep (about 2 seconds) then release it. Self-test
may also be run by using HP Power Manager.
Results of a Self-Test: All the LEDs will be lit and the UPS will emit
several short beeps as it momentarily switches to battery to test its
charge and load capacity. The test will last at most 10 seconds. If the
inverter is overloaded, the " " LED will stay lit and the UPS will con-
tinue to beep after the test; if this happens, remove some of the load and
run the self-test again. If the batteries seem weak, the "
stay lit and the UPS will continue to beep after the test; if this happens,
let the UPS charge its batteries for 12 hours and repeat the test. If the
condition persists, contact an HP authorized service representative.
CAUTION: Do not unplug your UPS to test its batteries. This will
remove safe electrical grounding and may introduce a damaging
surge into your network connections.
