Introduction

UPS Model and Battery Configurations

This UPS is designed to work with single-phase, three-wire, AC power sources. There are two important considerations when selecting the UPS model and battery configuration to properly safeguard your equipment:

:Load requirements

:Battery times

Load Requirements

The load is the equipment to be protected by the UPS. Select the UPS model that meets the power consumption requirements of the load in volt-amperes (VA). The total load VA should not exceed the UPS VA rating. To determine the total load requirements:

1.Obtain the load ratings from either the nameplate or operator’s manual of the equipment to be protected by the UPS. The ratings are listed in either watts (W), amperes or amperes max (A), or volt-amperes.

2.If the rating is in watts, multiply by 1.4 to obtain the VA requirement (this is the typical relationship between watts and volt-ampere ratings in most computing equipment). However, in some new computing equipment, the power supply is power-factor corrected and the watts rating equals the VA requirement. Check with the manufacturer to determine applicability.

If the rating is in amperes or amperes max, multiply by the input voltage to obtain the VA requirement.
