Safety Considerations

The UPS enclosures are designed for industrial or computer room applications. and

contain safety shields behind the doors. However, the UPS is a sophisticated power

system and should be handled with appropriate care, following these guidelines:

l

Keep surroundings clean and tree

horn

excess moisture.

l

Do not operate the UPS close to gas or

elect&

heat

sources.

l

The system is not intended for outdoor use.

l

The UPS operating environment should be maintained within the

parameters stated in this book.

l

Keep the UPS doors closed to ensure proper cooling airflow and

to protect personnel from dangerous voltages inside the unlt.

l

The UPS contains

ita

own power source. Lethal voltages are’

present even when the UPS Is disconnected from utility power.

WARNING:

:

Only AUTHORIZED SERVICE PERSONNEL should parformeervlce or

maintenance on the UPS or battery.

If service or routine UPS maintenance is required:

l

Be sure all power

is

dlaconnected before performing installation

or service.

RISK OF ELECTRIC SHOCK

There Is a risk ot eleciric shock present, and you should observe

associated waminge. me UPS contains high voltages.

I

8

Your UPS functions automaticatly to supply AC electrical power to your crittcal

load. The UPS ahvays operates in one of three modes:

l

In Norma/ mode, the critical load is supplied by the inverter, which

derives its power from rectified utility AC power. In this mode, the

rectifier also provides charging current for the battery.

-

In Saffery mode, the battery cabinet provides DC power, which

maintains inverter operation. The battery

supports

the critical load.

l

In

&pass

mode, the critical load is directly supported by the utility

through an isolation

transfomw.

The UPS continually monitors itself and the incoming utility power, and automatically

swftches between these modes as required, with no operator imerventfon. The

sophisticated detection and switching logic inside the UPS ensures that operating mode

changes are automatic and transparent to the critical load. The UPS switches operating

modes in response to these sysfem

even&

l

A command is an intervention that is externally initiated by an operator

or by some site action. A command causes the UPS to switch

operating modes: it usually does not require any further actton by you.

l

A nofice is a minor system event that may or may not

&ire

your

attention.

l

An a/arm is a system event that requires immediate operator

intervention.

System events, alarm horns, and indicator lights are described in ‘Responding to System

Events’ on page 45.

Normal Mode

In Normal mode, utility AC power is supplied to the rectiier. The rectiier supplies DC

power to the inverter, which then supplies the critical load with AC power. The rectiier also

provides charging power to the battery. The battery charge condiiin is monitored by the

UPS and reported by a status indicator on me Monitor Panel. The message “UPS

Supplying Load’ appears in the status area of me LCD screen.

Battery Mode

The UPS transfers to Battery mode automatically if a utility power outage occurs, or tithe

utility power does not conform to specified parameters. In Battery mode, the battery

provides emergency DC power, which the inverter converts to AC power. When the UPS

switches to Battery mode, its alarm indications depend on the cause and on the battery

charge state. The length of time the system can operate in Battery mode depends on

loading and the battery supply capacity.

is approximatefy 1 minute, depending on battery capa&ty and the amount of loading.

tf incoming power rehrms to within specified parameters, the UPS automaticaffy returns to

Normal mode and alarm indications dear. However, the process of returning to Normal

mode is not instantaneous. The rectifier gradually draws increasing power from the

incoming utility until Normal mode is achieved.
