1 Important safety instructions

This manual contains important instructions for

models DPA 250 S4 that should be followed

during installation and maintenance of the UPS.

It also provides guidelines to check delivery and

is in- tended for people who plan the installation,

installation, commission and use or service the

UPS system and/or the battery cabinet. The

reader is expected to know the fundamentals of

electricity, wiring, electrical components and

electrical schematic symbols.

READ ALL SAFETY AND OPERATING

INSTRUCTIONS BEFORE OPERATING THE

UPS SYSTEM. OBSERVE TO ALL WARNINGS

ON THE UNIT AND IN THIS MANUAL

DANGER

• SERVICING THE UNIT SHOULD BE

PERFORMED OR SUPERVISED BY

PERSONNEL KNOWLEDGEABLE ABOUT

BATTERIES AND REQUIRED PRECAUTIONS.

• RISK OF ELECTRIC SHOCK - THIS UNIT

RECEIVES POWER FROM MORE THAN

ONE SOURCE - DISCONNECTION OF AC

SOURCE(S) (AND THE DC SOURCE) IS

REQUIRED TO DE-ENERGIZE THIS UNIT

BEFORE SERVICING

• THERE IS DANGER OF AN ELECTRICAL

IMPACT.

• RISK OF EXPLOSION IF USING AN

INCORRECT BATTERY TYPE.

• DO NOT EXCEED UPS AND/OR BATTERY

CABINETS RATING LABELS.

• AS THE BATTERY LIFE DEPENDS ON THE

ROOM TEMPERATURE, FOR THE UPS

WITH INTERNAL BATTERY MODULES,

AN ENVIRONMENT WITH A CLIMATE

CONTROLLED SYSTEM IS

RECOMMENDED IN ORDER TO

MAINTAIN THE ROOM TEMPERATURE

1.2 Safety rules

The UPS system operates with mains, batteries or

bypass power carrying high currents and volt-

age. The correctly installed UPS system is

grounded to earth and IP 20 rated against electric

shocks and foreign objects when all dead fronts

are in place. Installation and service should be

carried out by the manufacturer’s qualified tech-

nicians or their certified service partners.

COMMISSIONING AND OPERATIONS

INSIDE THE UPS MUST BE CARRIED OUT

BY A CERTIFIED SERVICE ENGINEER OF

THE MANUFACTURER OR BY AN AGENT

CERTIFIED BY THE MANUFACTURER.

BY NOT FULFILLING THIS OBLIGATION,

THE PRODUCT MAY LOSE ITS WARRANTY

WARNING

INSTALLATION SHALL BE IN COMPLIANCE

WITH ALL APPLICABLE NATIONAL, STATE,

AND LOCAL CODES

Follow all operating and user instructions.

WARNING

EAD THE INFORMATION, IN ORDER TO

AVOID DAMAGE TO EQUIPMENT

DANGER

KEEP OUT OF BATTERY POLES WHICH

CONTAIN DANGEROUS DC-VOLTAGES

CAUSING FATAL ACCIDENTS. NOTE:

MANIPULATION ON THE BATTERY SYSTEM

SHOULD ONLY BE DONE BY TRAINED

SERVICE AND MAINTENANCE PERSONNEL

OF THE MANUFACTURER OR HIS CERTIFIED

SERVICE PARTNERS. INAPPROPRIATE

MANIPULATIONS OF THE BATTERIES CAN

CAUSE LIGHTNING SPARKS.

A BATTERY CAN PRESENT A RISK OF

ELECTRICAL SHOCK AND HIGH SHORT

CIRCUIT CURRENT. THE FOLLOWING

PRECAUTIONS SHOULD BE OBSERVED

WHEN WORKING ON BATTERIES:

BEFORE READING THE OPERATING MANUAL, PLEASE CAREFULLY READ THIS CHAPTER ON IMPORTANT

SAFETY INSTRUCTIONS

91 IMPORTANT SAFETY INSTRUCTIONS

DANGER

a. REMOVE WATCHES, RINGS OR OTHER

METAL OBJECTS.

b. USE TOOLS WITH INSULATED

HANDLES.

c. WEAR RUBBER GLOVES AND BOOTS.

d. DO NOT LAY TOOLS OR METAL PARTS

ON TOP OF BATTERIES.

e. DISCONNECT THE CHARGING SOURCE

PRIOR TO CONNECTING OR

DISCONNECTING OF BATTERY

TERMINALS.

f. ESTABLISH IF THE BATTERY IS

INADVERTENTLY GROUNDED. IF

INADVERTENTLY GROUNDED, REMOVE

SOURCE FROM GROUND. CONTACT

WITH ANY PART OF A GROUNDED

BATTERY CAN RESULT IN ELECTRICAL

SHOCK. THE LIKELIHOOD OF SUCH

SHOCK CAN BE REDUCED IF SUCH

GROUNDS ARE REMOVED DURING

INSTALLATION AND MAINTENANCE

(APPLICABLE TO EQUIPMENT AND

REMOTE BATTERY SUPPLIES NOT

HAVING GROUNDED SUPPLY CIRCUIT.

WARNING

THE UNIT IS HEAVY AND MAY TIP DURING

TRANSPORTATION CAUSING SERIOUS

INJURY IF UNPACKING INSTRUCTIONS

ARE NOT CLOSELY FOLLOWED.

The only user operations permitted are:

• Start up and shut down of the UPS system and/

or UPS modules (excluding the commissioning

start up).

• Control of the battery circuit breaker, UPS out-

put switch and Manual Bypass switch.

• Monitoring of the UPS system by the central

graphical display and the UPS Module by the lo-

cal control panel.

• Remote monitoring of the UPS system by SNMP,

Modbus and I/O relays interfaces

The user must follow the precautions and only

perform the operations described. Also in these

measures the operator of the UPS System must

observe the instructions in this manual. Any devi-

ations from the instructions could be dangerous

to the user or cause accidental load loss.

THE MANUFACTURER WILL NOT BE HELD

RESPONSIBLE FOR DAMAGES CAUSED THROUGH

INCORRECT MANIPULATION OF THE UPS SYSTEM.

DANGER

IT IS PROHIBITED TO REMOVE ANY PARTS

FROM THE UPS SYSTEM OR FROM ANY

OPTIONAL PART (E.G. BATTERY CABINET).

THERE IS A DANGER OF ELECTRICAL SHOCK!

DANGER

HIGH FAULT CURRENTS (LEAKAGE

CURRENTS):

BEFORE CONNECTING THE MAINS YOU

MUST ENSURE THAT THERE IS A PROPER

EARTH CONNECTION!

DANGER

THE USER MUST DISPLAY A WARNING

SHIELD ON ALL PRIMARY UPS CIRCUIT

BREAKERS. THE SERVICE PERSONNEL HAS

TO BE INFORMED ABOUT DANGEROUS

VOLTAGES. THE WARNING PANELS MUST

CONTAIN THE FOLLOWING TEXT (OR

SIMILAR): “BEFORE STARTING WITH THE

MAINTENANCE WORK ON THE CIRCUIT

BREAKERS MAKE SURE THE UPS IS

ISOLATED”.

RESTRICTIONS OR ADDITIONAL

MEASURES MAY BE NEEDED TO PREVENT

DISTURBANCES

The UPS must be installed according to the rec-

ommendations in this manual. To operate the UPS

at peak efficiency, your installation site should

satisfy the environmental parameters outlined in

this manual. Excessive amount of dust in the op-

erating environment of UPS may cause damage or

lead to malfunction. The UPS should be always

protected from the outside weather and sun-

shine. If you intend to operate the system at an al-

titude higher than 1000 meters above sea level,

contact your local sales or service office for im-

portant information about high altitude opera-

tion. The operating environment must meet the

weight, airflow, size and clearance requirements

specified in the technical datasheet.

inlets are located at the front of the cabinet, and

outlets at the top of the cabinet. You must allow

clearance on the top of the cabinet for proper air

circulation. Refer to the chapter "9.2 UPS loca-

TRAINED BY SERVICE TECHNICIANS OF

THE MANUFACTURER OR HIS CERTIFIED

SERVICE PARTNERS ARE ALLOWED TO

START UP AND COMMISSIONING THE UPS

SYSTEM.

The control and monitoring communication for

the parallel UPS units are secured by using a

ring-bus communication. The ring-bus technique

loops back the parallel communication cable from

the last frame in the system. This introduces an

alternative communication path in case one cable

in between two UPS units is disconnected for

whatever reason.
