    1.0 Introduction

    1.1 Overview

    The UPS is a high performance standby un interrup tible pow er source designedto protect computers and peripheral devices such as monitors, modems, tapedrives, etc. from u tility line failures w hich could resu lt in the loss or corru ptionof 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 alternativepow er source. This alternative power is derived from a battery within the UPSand provides the user with amp le time to save files and properly close operations.A chart in section 9.0 shows how much time your equipment can remainopera ting du ring a u tility failure before the UPSs batteries are drained . Und ernormal conditions when the utility voltage is within proper limits, the UPSmaintains the battery in a charged condition and serves to isolate your equip-ment from su rges and high frequency electrical noise.

    After following the installation procedures and reading all the safety instruc-tions, youre ready to enjoy compu ting free from the w orry of pow er problemsand the time consum ing process of constantly saving you r files!

    1.2 Test / Alarm Disable switch

    A du al function Test / Alarm Disable switch (400VA, 450VA, 600VA, 900VA and

    1250VA models) allows you to check for p rop er operation by initiating a transferto on-battery operation. This test ensures that the UPS is not overloaded and w illsup port the system load d ur ing an actual power disturbance. By using the Testfunction throughou t the life of the UPS, you can estimate w hen the UPS's batteryshou ld be replaced. Dur ing a utility failure, the Alarm Disable portion of theswitch can be pressed to silence the audible alarm.

    1.3 Option switchesOption switches (400VA, 450VA, 600VA, 900VA and 1250VA models) allow youto adjust the UPS for applications where frequent or rapid utility voltagefluctua tions cause the UPS to transfer to on-battery operation too often. Audiblealarm functions can be altered so that warning of utility failure or low batteryconditions are given when desired.

    1.0 Introduction

    1.4 Site wiring fault indicator

    A site wiring fault indicator warns you of hot-neutral reversal, open grou nd andoverloaded n eutral fau lts. Faulty wiring prevents the safety features and surgeprotection circuits bu ilt into this UPS from opera ting properly. Check thisindicator during installation or whenever your building's wiring has been

    serviced - call a qu alified electrician if the ind icator is illuminated .

    1.5 Surge suppression and EMI/RFI filtering

    The UPS provides high performance surge sup pression and EMI/ RFI (electro-magnetic and rad io frequency interference) filtering. The UPS sup presses surgesdefined by the ANSI C62.41 (form erly IEEE 587) Category A and B standard tolevels well below th at wh ich is compatible with your compu ter.

    1.6 Remote interface

    A remote computer interface port (400VA, 450VA, 600VA, 900VA and 1250VAmodels) capable of signalling utility failure and low battery conditions isprovided for unattended shu tdow n of comp uter operations. When teamed withPowerChute UPS monitoring software, you may select operation of pow er eventlogging, pow er event notification, automatic restart up on power restoration, and

    battery conservation features.

    s Connect the Uninterru ptible Power Source to a two-pole, three-wire ground -ing mains receptacle. The receptacle mu st be connected to appropriate branch

    protection (fuse or circuit breaker). Connection to any other type of receptaclemay result in a shock hazard and may violate local electrical codes.

    s This Uninterru ptible Power Source has an internal energy source (the battery)that cannot be d e-energized by the user. The output may be energized when theunit is not connected to a mains supply.

    s To properly de-energize the Uninterrup tible Power Source in an emergency,

    move the I/O switch to the O (off) position and d isconnect the p ower cord fromthe m ains.

    s Avoid installing the Un interrup tible Power Source in locations w here there iswater or excessive hum idity.

    s Do not allow water or any foreign object to get inside the Uninterruptible

    Power Source. Do not pu t objects containing liquid on or near the un it.
