3.3Determining 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	Computer Co
120V 2.7A	Pentium Pro 200MHz
50 / 60 Hz	120V 2.0A
SN: Q771515388	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.
