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 infor-
mation, including a list of available SNMP, networking management and
connectivity products.
Output Breakers: Your UPS features one or more breakers that pro-
tect your UPS from output overload. If one or more breakers trip,
remove some of the load on the circuit(s), then reset them by press-
ing the breaker switch(es) in.
Battery Charge Level Switch (select models): Select models feature
a switch that controls the UPS system’s battery charge rate. If you
connect any external batteries, set the Battery Charge Level Switch to
the up position. This will increase your UPS’s charger output so the
additional batteries charge faster. Note: the switch to the right of the
Battery Charge Level Switch is inactive and will not affect UPS operation
regardless of its position.
CAUTION! DO NOT set the Battery Charge Level Switch to the
up position without an external battery connected. There is a risk
of damaging the UPS’s internal battery system.
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 PWM 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.
