HOW TO DETERMINE THE POWER REQUIREMENTS OF YOUR EQUIPMENT
1. Make sure that the total
Volt-Amp (VA)
requirements of your computer, monitor and peripheral
equipment does not exceed
1200VA
.
2. Insure that the equipment plugged into the three battery power-supplied outlets does not exceed
the UPS unit’s rated capacity
(625VA/325W for CPS625AVR)
. If rated unit capacities are ex-
ceeded, an overload condition may occur and cause the UPS unit to shut down or the circuit
breaker to trip.
3. If the power requirements of your equipment are listed in units other than Volt-Amps (VA), convert
Watts (W) or Amps (A) into VA by doing the calculations below. Note: The below equation only
calculates the maximum amount of VA that the equipment can use, not what is typically used by
the equipment at any one time. Users should expect usage requirements to be approximately
60% of below value.
TO ESTIMATE POWER REQUIREMENTS:
Watts (W) x 1.8 = VA or Amps (A) x 120 = VA
Add the totals up for all pieces of equipment and multiply this total by .6 to calculate actual require-
ments.
There are many factors that 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 80% of the
unit’s capacity.
HARDWARE INSTALLATION GUIDE
1. Your new UPS may be used immediately upon receipt. However,
recharging the battery for at least four hours
is recommended to
insure that the battery’s maximum charge capacity is achieved.
Charge loss may occur during shipping and storage. To recharge
the battery, simply leave the unit plugged into an AC outlet
and turn
on the power switch.
2. If you wish to use the software, connect the enclosed serial interface
cable to the serial port on the UPS and an open serial port on the
computer. If you are not going to use the software, you do not need
to connect the cable.
3.
With the UPS unit off and unplugged, connect your computer and
monitor into the battery power supplied outlets. Plug your peripheral
equipment (printer, scanner, speakers) into the full-time surge protection out-
lets. DO NOT plug a laser printer, copier, space heater, vacuum or other lar-
ge electrical device into the UPS. The power demands of these devices will
overload and possibly damage the unit.
4. To protect a fax, telephone or modem line, connect a telephone cable from the
wall jack outlet to the in jack of the UPS. Connect a telephone cable to the
out-jack on the UPS to the modem port of the computer.
5. Plug the UPS into a 2 pole, 3 wire grounding receptacle (wall outlet). Make
sure the wall branch outlet is protected by a fuse or circuit breaker and
does not service equipment with large electrical demands (e.g. refrig-
erator, copier, etc…). Avoid using extension cords. If used, the ex-
tension cord must be rated for 10 amps.
6. Depress the power switch to turn the unit on. The power on indicator
light will illuminate.
7. If an overload is detected, an audible alarm will sound and the unit will
emit one long beep. To correct this, turn the UPS off and unplug at least one piece of equipment
from the battery power supplied outlets. Wait 10 seconds. Make sure the circuit breaker is de-
pressed and then turn the UPS on.
