3.3 Determining How Much Equipment You Can Connect to Your UPS
1.
Make a list of all equipment that requires protection.
2.
Each piece of equipment has voltage and current (VA) ratings printed on
the back label (see examples below). Your equipment may have a voltage
rating such as 88-264V. Since the standard voltage in the United States is
120V, you should use 120V in your calculations.
ViewSonic G810
120V 2.7A
50 / 60 Hz
SN: Q771515388
Computer Co
Pentium Pro 200MHz
120V 2.0A
50/60 Hz
SN: 123456
3. Multiply the voltage and current of each piece of equipment (VA
requirements); for example, 120V x 2.7A = 324VA, 120V x 2.0A = 240VA.
Add up the VA requirements for each device; for example, 324VA +
240VA = 564VA.
4.
Make sure that your UPS has at least as much VA capacity as your
equipment requires.
3.4 Powering Up Your UPS
1. For 110/120V versions, connect the power cord to a verified grounded 3-
wire receptacle. For 2X0V versions, please refer to Sec 3.5 .
2. Power up the UPS by press the On/Off button for 2 seconds( till the LED
light ) on the front panel.
