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. Visit tripplite.com 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: 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.
Output Breaker(s): 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.
