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.
Should your UPS require battery replacement, visit Tripp Lite on the Web at
www.tripplite.com/products/battery-finder/ to locate the specific replacement
battery for your UPS.
External Battery Connector (Select Models Only): Use to connect one or
more Tripp Lite battery packs for additional runtime. Refer to the label next to
the connector to determine the appropriate type of battery pack to use. Refer
to the battery pack instruction manual for complete installation information and
important safety warnings.
Input Breaker: Protects your electrical circuit from overcurrent draw from the
UPS load. If breaker trips, remove some of the load, then reset it by pressing the
breaker in.
Equipotential Connection: Use this to connect any equipment that requires a
protective earth ground.
Power Sensitivity Adjustment: This dial is normally set fully counterclockwise,
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

DELAY
areas with poor utility power or where the 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 system's output can be
evaluated without disrupting critical operations.
