Power Sensitivity/Lowline Adjustment (select models only):
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 distor-tion could
cause the UPS to switch to battery too often, draining its bat-tery 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 encoun-tered.
Automatic Voltage Regulation:
During brownouts, your UPS will auto-
matically correct low AC line voltage. When automatic voltage regulation
is operating, your UPS may be heard to click gently. This is a normal,
automatic operation of your UPS, and no action is required on your part.
Basic Operation
Storage
All connected equipment should be turned off, then disconnected from the UPS to avoid bat-tery
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 extend-ed 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 bat-teries 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.
