Uninterruptible Power Supply
Determining The Power Requirements Of Your Equipment
1.
Make sure the total Volt-Amp (VA) requirements of your connected equipment does not exceed the maxi
-
mum VA rating for the UPS. The maximum VA ratings are shown in the Specifications section of this docu
-
ment.
2.
Ensure that the equipment plugged into the battery-powered outlets does not exceed the UPS rated ca
-
pacity. If UPS rated capacities are exceeded, an overload condition may occur and cause the UPS to shut
down and trip the circuit breaker.
3. If the power requirements of your equipment are listed in values other than Volt-Amps (VA), convert Watts
(W) or Amps (A) into VA by doing the calculations below. Note: The equation below only calculates the
maximum amount of VA that the equipment can use, not what is typically used by the equipment at any
given time. Users should expect usage requirements to be approximately 60% of the value to estimate
power requirements:
_____ Watts (W) x 1.67 = _____ VA or _____ Amps (A) x 120 = _____ VA
Add the totals for all of the equipment and multiply this total by 0.65 to calculate actual power require
-
ments.
Note:
Many factors can affect the amount of power that your computer system will require. The total load
that you will be placing on the battery-powered outlets should not exceed 85% of the UPS capacity.
Hardware Installation Guide
1.
Your new UPS may be used immediately upon receipt, however, charging the battery for at least 4 hours is
recommended to ensure that the batteries maximum charge capacity is achieved. Charge loss may occur
during shipment and storage. To recharge the battery, plug the power cord into the correct type AC wall
outlet and turn the power switch on. Note: Xtreme Power units will charges the battery with the power
switch in either the on or off position.
2.
With the UPS off and unplugged, connect your computer, monitor, and/or any other externally powered
equipment into the battery power supplied outlets. DO NOT plug a laser printer, copier, space heater,
vacuum, or other large electrical device into the UPS. The power demands of these devices will overload
and possibly damage the UPS.
3. Plug the UPS into a 2 pole, 3 wire grounded receptacle (AC wall outlet) as rated in the Specifications sec
-
tion of this document. Make sure the wall outlet is protected by a fuse or circuit breaker and does not
service equipment with large inrush electrical demands (e.g. refrigerator, copier, etc). Note: DO NOT use
extension cords or power or surge strips on the input or the output of the UPS.
4. Depress the power switch to turn the UPS on. The power on LED indicator, and charging LED will illuminate
after the UPS initial test to indicate the UPS is switched “ON”.
5.
If an overload is detected, an audible alarm will sound and the UPS will emit one long beep every 2-4
seconds. To correct this, turn the UPS off and unplug at least one piece of equipment from the battery-
powered outlets. Wait 10 seconds. Make sure the circuit breaker is depressed and then turn the UPS on.
6.
Your UPS is equipped with an auto-charge feature. When the UPS is plugged into an AC wall outlet and
there is acceptable AC voltage present, the battery will automatically recharge. Charging is controlled by
firmware to rapidly charge units to 15VDC (600/800VA units) and 29VDC (1200/1500VA units). After this
threshold is met, the XVT places a float charge to maintain battery energy, and the charging light will con
-
tinue to stay on during this time.
7. To maintain optimal battery charge, leave the UPS plugged into an AC wall outlet with the power switch
turned on at all times.
8.
To store your UPS for an extended period of time, cover and store it with the battery fully charged. Re
-
charge the battery every two months to maintain battery life.
