Storage & Service
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.

Power Sensitivity Adjustment: This dial is normally set fully counter-
clockwise, 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 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 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.
