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
(773) 869-1234 for more information, including a list of available SNMP, network
management and connectivity products.
Power Sensitivity Adjustment (Select Models): 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. The specifications section of this
manual lists the Tripp Lite external battery packs that are compatible with your
model. Refer to instructions available with the battery pack for complete con-
nection information and safety warnings.
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.
Output Breaker(s) (select models): Protect your UPS from output overload. If
one or more breakers trip, remove some of the load on the circuit(s), then reset
them by pressing the breaker switch(es) in.
Ground Screw: Use this to connect any equipment that requires a chassis ground.
