Storage
All connected equipment should be turned off, then disconnected from the UPS to avoid battery drain.
Unplug your UPS from its AC receptacle, then press and hold its ON/OFF button to deactivate
it. Your UPS is now ready for storage. If you plan on storing your UPS for an extended period
of time, fully recharge the UPS batteries once every three months by plugging the UPS into a
live AC outlet and letting the UPS charge for 4 to 6 hours. If you leave your UPS batteries
discharged for an extended period of time, they will suffer a permanent loss of capacity.
Service
If returning your UPS for service, contact your local Tripp Lite dealer or distributor. They will
refer you to a service center. Please carefully pack the UPS using the ORIGINAL PACKING
MATERIAL that came with the unit. Enclose a letter describing the symptoms of the problem.
If the UPS is within the warranty period, enclose a copy of your sales receipt.

Basic Operation

Other UPS Features

Power Sensitivity/Lowline Adjustment: This dial is normally set
fully counterclockwise, which enables the UPS to protect against
waveform distortions in its AC input. When such distortion occurs,
the UPS will normally switch to providing PWM sinewave power
from its battery reserves for as long as the distortion is present. In
some areas with poor utility power or where the UPS's input power
comes from a backup generator, frequent brownouts and/or chronic
waveform distortion could cause the UPS to switch to battery too
often, draining its battery reserves. You may be able to reduce how
often your UPS switches to battery due to waveform distortion or
brownouts 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 and reduces the voltage point at
which it switches to battery.
NOTE: The further the dial is adjusted clockwise, the greater the degree of waveform distortion
and the lower the input voltage 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. The experiment should last long
enough to assure that all expected line conditions are encountered.
