Basic Operation

Power Sensitivity Adjustment: This dial is normally set fully counter-clockwise,
which enables the UPS to provide maximum protection against waveform distortions
in its AC input. When such distortion occurs, the UPS will normally switch to
providing 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 mod-
erate 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 con-
nected equipment. When experimenting with different settings for this dial,
operate connected equipment in a safe test mode so that the effect on the equip-
ment of any waveform distortions in the UPS’s output can be evaluated without
disrupting critical operations.
External Battery Connector: Use to connect Tripp Lite external battery packs for
additional runtime. Refer to instructions available with the battery pack for
complete connection information and safety warnings.
Battery Charge Level Switches: Controls the UPS system’s battery charge rate.
If you connect any external batteries, set the Battery Charge Level Switches to
the down position. This will increase your UPS's charger output so the addition-
al batteries charge faster. CAUTION! DO NOT set the Battery Charge Level
Switches to the down position without an external battery connected. There
is a risk of damaging the UPS’s internal battery system.
Input Breaker: Protect your electrical circuit from overcurrent draw from the
UPS load. If these breakers trip, remove some of the load, then reset them by
pressing the breaker(s) in.
Ground Screw: Use this to connect any equipment that requires a chassis ground.
