Basic Operation - Tripp Lite SMART750TSU Owner's Manual

Quick Installation
Optional Installation
All models include a USB communication port
and tel/DSL/Ethernet surge protection jacks (not
compatible with PoE applications). Select models
will also include an RS-232 serial port. These
connections are optional, as the UPS will work
properly without them.

Basic Operation

UPS ON/OFF
• Plug the UPS into a live, grounded outlet.
The entire LCD screen will illuminate for 5 seconds, then the display will report output
voltage of "0V". The BATTERY / SURGE PROTECTED outlets will be OFF and the SURGE
ONLY outlets will be ON. The battery charger will engage as necessary.
• Plug equipment into the UPS: You will overload the UPS if the total volt-amp (VA) ratings
for all the equipment connected to the BATTERY/SURGE PROTECTED outlets exceed the
UPS output capacity. To find your equipment's VA ratings, look on their nameplates. If the
equipment is listed in amps (A), multiply the number of amps by 120 to determine VA. For
example: 1A × 120 = 120VA.
• Turn the UPS on: Press and hold the power button until the alarm begins to sound, then
release. The UPS alarm will beep once briefly. The BATTERY/SURGE PROTECTED outlets
will begin passing AC line power. The UPS will automatically recharge internal batteries
as needed. Once turned on, your UPS is ready to protect connected equipment from
blackouts, brownouts, overvoltages and transient surges.
• Turn the UPS off: Press the power button.
Note: The UPS system will function properly upon initial startup; however, maximum runtime for the unit's
battery will only be accessible after it has been charged for 24 hours.
