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 rang for the UPS. The maximum VA rangs are shown in the Specicaons secon of this docu-
ment.
2. Ensure that the equipment plugged into the baery-powered outlets does not exceed the UPS rated ca-
pacity. If UPS rated capacies are exceeded, an overload condion 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 Was
(W) or Amps (A) into VA by doing the calculaons below. Note: The equaon below only calculates the
maximum amount of VA that the equipment can use, not what is typically used by the equipment at any
given me. Users should expect usage requirements to be approximately 60% of the value to esmate
power requirements:
_____ Was (W) x 1.67 = _____ VA or _____ Amps (A) x 120 = _____ VA
Add the totals for all of the equipment and mulply this total by 0.65 to calculate actual power require-
ments.
Note: Many factors can aect the amount of power that your computer system will require. The total load
that you will be placing on the baery-powered outlets should not exceed 85% of the UPS capacity.
Hardware Installaon Guide
1. Your new UPS may be used immediately upon receipt, however, charging the baery for at least 4 hours is
recommended to ensure that the baeries maximum charge capacity is achieved. Charge loss may occur
during shipment and storage. To recharge the baery, plug the power cord into the correct type AC wall
outlet and turn the power switch on. Note: Xtreme Power units will charges the baery with the power
switch in either the on or o posion.
2. With the UPS o and unplugged, connect your computer, monitor, and/or any other externally powered
equipment into the baery 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 Specicaons sec-
on 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
aer the UPS inial 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 o and unplug at least one piece of equipment from the baery-
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 baery will automacally recharge. Charging is controlled by
rmware to rapidly charge units to 15VDC (600/800VA units) and 29VDC (1200/1500VA units). Aer this
threshold is met, the XVT places a oat charge to maintain baery energy, and the charging light will con-
nue to stay on during this me.
7. To maintain opmal baery charge, leave the UPS plugged into an AC wall outlet with the power switch
turned on at all mes.
8. To store your UPS for an extended period of me, cover and store it with the baery fully charged. Re-
charge the baery every two months to maintain baery life.
