Quick Installation
Optional Installation
Select models (AVRT450U and AVRT650U) include
a USB communication port. The SMART550USB2
model includes tel/DSL/Ethernet surge protection
jacks (not compatible with PoE applications). These
connections are optional, as the UPS will work
properly without these connections.
Basic Operation
UPS ON/OFF
•
Plug the UPS into a live, grounded outlet.
The green
LED will illuminate, the battery charger will engage as necessary and the
SURGE PROTECTED outlets will begin passing power.
•
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 the power button
. 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:
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.
