1.0 Introduction

1.1 Overview

The UPS is a high performance standby uninterruptible power source designed to protect

computers and peripheral devices such as monitors, modems, tape drives, etc. from utility

line failures which could result in the loss or corruption of valuable data. In the event of

a utility failure such as a blackout, brownout, or sag, the UPS rapidly transfers loads

(computer equipment) to an alternative power source. This alternative power is derived

from a battery within the UPS and provides the user with ample time to save files and

properly close operations. A chart in section 9.0 shows how much time your equipment

can remain operating during a utility failure before the UPS’s batteries are drained. Under

normal conditions when the utility voltage is within proper limits, the UPS maintains the

battery in a charged condition and serves to isolate your equipment from surges and high

frequency electrical noise.

After following the installation procedures and reading all the safety instructions, your

computer equipment will be protected from hardware damage and loss of data caused by

power problems.

1.2 User replaceable battery

The UPS provides user-safe access to the batteries for quick, easy replacement. The UPS's

Test function (400VA and 600VA models) helps you determine when the battery is weak

and requires replacement. New battery kits can be obtained from your dealer or the

factory — simply call the Customer Service number on the cover of this manual. Your

UPS's old, worn battery can be returned in the new battery kit's packaging for recycling.

1.3 Option switches

Option switches allow you to adjust the UPS for applications where frequent utility voltage

fluctuations cause the UPS to transfer to on-battery operation too often. Audible alarm

functions can be altered so that warning of utility failure or low battery conditions are

given when desired.
