Basic Operation
Accessory Slot: Remove the small cover panel from this slot to install optional
accessories to remotely monitor and control your UPS. Refer to your accessory's
manual for installation instructions. Contact Tripp Lite Customer Support at
+1.773.869.1234 for more information, including a list of available SNMP,
network management and connectivity products.
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 moderate 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.
External Battery Connector (Select Models Only): 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 (Select Models Only): Controls the UPS
system's battery charge rate. If you connect any external batteries, set the Battery
Charge Level Switch to the down position. This will increase your UPS's charger
output so the additional batteries charge faster.

Input Breaker(s) (all models): 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.
