USB Port:
The USB port connects your UPS to any USB workstation
or server. Using this port, your UPS can communicate line-fail and
low-battery status to your computer. Use with Tripp Lite software and
any USB cable to automatically save open files and shut down equipment
during a blackout. See PowerAlert manual.
DB9 Port (Select Models Only):
The DB9 port connects your UPS
to any workstation or server. Use with Tripp Lite’s PowerAlert UPS
monitoring software and a DB9 cable to enable your computer to
automatically save open files and shut down equipment during a
blackout. The UPS can also report power availability and UPS status,
and select UPS models have other capabilities. See PowerAlert manual.
Battery Replacement Door:
Under normal conditions, the original
battery in your UPS will last several years. Battery replacement
should be performed only by qualified service personnel. Refer to
“Battery Warnings” in the Safety section on page 2.
External Battery Connector (Select Models Only):
Use to connect
battery pack(s) for additional runtime. Refer to Specifications and/or
the label next to the connector to determine the appropriate variety of
battery pack to use. Refer to the battery pack instruction manual for
complete installation information and important safety warnings.
Input Breaker:
Prevents high input current from damaging the UPS or the
attached load. If this breaker trips, make sure your UPS is connected
to nominal 120V AC power before resetting the circuit breaker by
pushing the breaker switch in to reset.
Charge Level Switch:
This switch should be set to the left unless
you have connected multiple external batteries, in which case you
may set it to EXTERNAL BATTERY, increasing your charger’s output
so the additional batteries recharge faster.
Power Sensitivity Adjustment:
This dial is normally set fully counter-
clockwise, which enables the UPS to protect against waveform
distortions in its AC input. When such distortion occurs, the UPS will
normally switch to providing PWM sine wave power from its battery
reserves for as long as the distortion is present. In areas with poor utility
power or where the UPS’s input power comes from a backup generator,
chronic waveform distortion could cause the UPS to switch to battery too
frequently, draining its battery reserves. You may be able to reduce how often
your UPS switches to battery due to waveform distortion by experimenting
with different settings for this dial. As the dial is turned clockwise,
the UPS becomes more tolerant of variations in its input power’s AC
waveform. NOTE: The further the dial is adjusted clockwise, the greater
the degree of waveform distortion the UPS will allow to pass to connected
equipment. When experimenting with different settings for this dial,
operate connected equipment in a safe test mode so that the effect on
the equipment of any waveform distortions in the UPS’s output can
be evaluated without disrupting critical operations.
