1.0 SAFETY PRECAUTIONS

Read this m a nual thoroughly, paying special attention to the sections that apply to you, before
working with the UPS. Retain this manual for use by installing personnel.

Under typical operation and with all UPS doors closed,only normal safety precautions are neces­sary. The area around the UPS system should bekept free from puddles of water, excess mois­ture, or debris.

Special safety precautions are required for procedures involving handling, installation, and main­tenance of the UPS system or the battery. Observe all safety precautions in this manual before
handling or installing the UPS system. Observe all precautions in the Operation and Mainte-
nance Manual, before as well as during performance of all maintenance procedures. Observe all
battery safety precautions before working on or near t he battery.

This equipment contains several circuits that are energized with high voltage. Only test
equipment designated for troubleshooting should be used. This is particularly true for oscillo­scopes. Always check with an AC and DC voltmeter to ensure safety before making contact or
using tools. Even when thepower i s turned Off, dangerously high potentials may exist at the
capacitor banks and at the batteries.

ONLY qualified service personnel should perform maintenance on the UPS system.

When performing maintenance with any part of the equipment under power, service personnel
and test equipment should be standing on rubber mats. The service personnel should wear insu­lating shoes for isolation fr om direct contact with the floor (earth g round).

Unless all power is removed from the equipment, one person should never work alone. Asecond
person should be standing by to assist and summon help in case an accident should occur.

Four types of mess ages are used throughout the manual to stress important text. Carefully read
the text below each Danger, Warning, Caution, and Note and use professional skills and prudent
care when performing the actions described by that text.

A Danger signals immediate hazards resulting in severe personal injury or death. For example:

DANGER

!

A DANGER SIGNALS IMMEDIATE HAZARDS WHICH WILL
RESULT IN SEVERE PERSONAL INJURY OR DEATH.

A Warning signals the presence of a possible serious, life-threatening condition. For ex ample:

WARNING

!

LETHAL VOLTAGES MAY BE PRESENT WITHIN THIS UNIT
EVEN WHEN IT IS APPARENTLY NOT OPERATING. OBSERVE
ALL CAUTIONS AND WARNINGS IN THIS MANUAL. FAILURE
TO DO SO COULD RESULT IN SERIOUS INJURY OR DEATH. DO
NOT WORK ON OR OPERATE THIS EQUIPMENT UNLESS YOU
ARE FULLY QUALIFIED TO DO SO!! NEVER WORK ALONE.

A Cautionindicates a condition that could seriously damage equipment and possibly injure per-
sonnel. For example:

CAUTION

!

Extreme care is n ecessary when removing shoring braces. Do not
strike the cabinet with hammers or other tools.

A Note emphasizes important tex t. If the note is not followed, equipment could be damaged or
may not operate properly. For example:

NOTE

If the UPS system has a blown fuse, the cause should be determined before
you replace the fuse. Contact Liebert Global Services.

Safety Precautions 3

2.0 INSTALLATION CONSIDERATIONS

Install your S er ies 600T UPS in accordance with the submittal drawing package and the follow­ing procedures.

A Liebert authorized representative must perform the initial system check-out and start-up to
ensure proper system operation. Equipment warranties willbe voided unless system start-up is
performedby a Liebert authorized representative. Contact your local Liebert sales r epresentative
or Liebert Global Services at 1-800-543-2378 to arrange for system start-up.

CAUTION

!

Read this ma nual thoroughly before attempting to wire or
operate the unit. Improper installation is the most significant
cause of UPS start-up problems.

Do not install this equipment near gas or electric heaters. It is
preferable to install the UPS in a restricted location to prevent
access by unauthorized personnel.

1. Proper planning will speed unloading, location, and connection of the UPS. Refer to

Figure 8 through Figure 58 and Appendix A - Site Planning Data.

2. Refer t o information later in this manual regarding the optio nal Battery Cabinets and
Transformer Cabinets. Observe all battery safety precautions when working on or

near the battery.

3. Use the shortest output distribution cable runs possible, consistent with logical equipment
arrangements and with allowances for future additions i f planned.

4. Recommended ambient operating temperature is 25°C (77°F). Relative humidity must be less
than 95%, non-condensing. Note that room ventilation is nece ssary, but air conditioning may
not be required. Maximum ambient o perating temperature is 40°C (104°F) without d erating.
The batteries should not exceed 25°C (77°F). At elevations above 4,000 feet (1219 meters)
derating may be required (consult your Liebert s ales representative).

5. Even though your Liebert UPS unit is at least 93% efficient, the heat output is substantial.
For more specific information, see Appendix A - Site Planning Data. Be sure
environmental conditioning systems can accommodate this BTU load, even during utility
outages.

6. The routing (inside th e facility) to the installation site, as well as the f l oor at the final
equipment location, must be capable of supporting the cabinet weight and the weight of any
moving equipment. The modules weigh up to 12,000 po unds. The batt er y cabinets weigh
between 3000 and 4900 pounds. The System Control Cabinets weigh between 1000 and 2550
pounds. Refer to Appendix A - Site Planning Data.

7. Plan the routing to ensure that the unit can move through all aisleways, doorways, and
around corners without risking dama ge. If the modules and batteries mu st be moved by
elevator, check the size of the door openings and the weight-carrying capacity of the elevator.

6.0 BATTERY INSTALLATION

6.1 Battery Safety Precautions

Servicing of batteries should be performed or supervised by personnelknowledgeable of ba tteries
and the required precautions. Keep unauthorizedpersonnel away from batteries.

When replacing batteries, use the same number and type of batteries.

CAUTION

!

Lead-acid batteries contain hazardous materials. Batteries must
be handled, transported, and recycled or discarded in accordance
with federal, state, and local regulations. Because lead is a toxic
substance, lead-acid batteries should be recycled rather than
discarded.

Do not open or mutilate the battery or batteries. Released
electrolyte is harmful to the skin and eyes. It may be toxic. Do not
dispose of battery or batteries in a fire. The battery may explode.

A battery can present a risk of electrical shock and high short
circuit current. The following precautions should be observed
when working on batteries:

1. Remove watches, rings, or other metal objects.

2. Use tools with insulated handles.

3. Wear rubber gloves and boots.

4. Do not lay tools or metal parts on top of batteries.

5. Discon nect charging source prior to conn e cting or
disconnecting battery terminals.

6. Determine if battery is inadvertently grounded. If
inadvertently grounded, remove source of ground. Contact
with any part of a grounded battery can result in electrical
shock. The likelihood of such shock will be reduced if such
grounds are removed during installation and maintenance.

Lead-acid batteries can present a risk of fire because they
generate hydrogen gas. The following procedures should be
followed:

1. DO NOT SMOKE when near batteries.

2. DO NOT cause flame or spark in battery area.

3. Discharge static electricity from body before touching
batteries by first touching a grounded metal surface.

12 Battery Installation

6.2 Matching Battery Cabinets

Two sizes ofoptional battery cabinets areavailable. Refer to Figure 16 to Figure 18. The battery
cabinet cells range from 90 to 150 Ampere-hours.The same model battery cabinet may be paral­leled in multiple cabinet strings for additional capacity. Battery capacity (in minutes) at your
installation will depend on cabinet model, number of cabinets, and amount of critical load on the
UPS.

1. Han d ling. The Battery Cabinet weighs 3000 to 4900 pounds. Forklift slots are provided for
easy handling.

2. Cabinet Inspection. Remove all panels and visually inspect the batteries, bus connections,
and cabinet for any d amage. Exercise caution; v oltage is present within the Battery
Cabinet even beforeinstallation.If there aresigns of damage, do notproceed. Call Liebert
Global Services at 1-800-543-2378.

3. Battery Storage. The batteries used in the Battery Cabinet have an excellent ch arge
retaining characteristic. The batteries can be stored for up to six months without any
appreciable deterioration. Self-discharge rate of the batteries is approximately 3% permonth
when the batteries are stored in temperatures of 15°C to 25°C (59°F to 77°F). If the Batt ery
Cabinet is planned to be stored for longer than sixmonths, contact Liebert Customer Service
for recommended action.

4. Installation. The Battery Cabinet(s) can be located conveniently next to each UPS module.
The front-access-only-design eliminates side and rear service clearance requirements.

• Environment. Locate the Battery Cabinet in a clean, dry environment. Recommended
temperature range for optimum performance and lifetime is 20°C (68°F) to 25°C (77°F).

• Service Clearance. Allow front access to the Battery Cabinet at all times for mainte­nance and servicing. Electrical codes require that the Battery Cabinet be installed with no
less than 3feet (1 meter)of clearance at the front of thecabinet when operating. Side and
rear panels do not require service clearance.

• Side Panels. Remove protective side panels to connect cabinets together. Panels are
retained at the bottom with three screws.

• Shield Plate. IftheBatteryCabinetsareboltedtothesideoftheUPSmodule,theshield
plate inside the Battery Cabinet should be on the side toward the UPS module for proper
UPS airflow. Move the shield if required by your Battery Cabinet location.

• Cables. Cables may be run between the cabinets through cutouts in the top of the cabi­net, eliminating the need for external conduit runs. Route cables before moving cabi-
nets into final position for bolting together. Remove top panels for access, if
required. No topor bottom entry cables are required, exceptfor remotely located cabinets
which require conduits.Refer to Figure 16 through Figure 18.

• Built-In Cabinets. Matching Battery Cabinets are designed as a bolt-on section to the
side of the UPS module cabinet. Use bolts (3/8"-16 x 1-1/4") to connect cabinet frames at
posts, two places front and two places rear. Brackets are provided to make rear connec­tions easier fr om inside the cabi net.

6.3 Non-Standard Batteries

When batteries other than a matching B attery Cabinet are used (not recommended), a remote
battery disconnect switch with overcurrent protection is required per the National Electrical
Code. Refer to Figure 53 and Figure 54. Contact yo ur Liebert sales representative regarding
this option.

1. Install battery racks/cabinets and batteries per manufacturer’s installation and mainten a nce
instructions.

2. Verify battery area has adequate ventilation and battery operating temperature complies
with manufacturer’s specification.

If you have any questions concerning batteries, battery rack s, or accessories, contact Liebert Glo­bal Services at 1-800-543-2378.

7.0 CONFIGURING YOUR NEU TRAL AND GROUND CONNECTION S

Improper grounding is the largest single cause of UPS installation and start-up problems. This is
not an easy subject, since grounding techniques vary significantly from site to site, depending on
several factors. The questions you should ask are:

• What is the configuration of the input power source? Most of the recommended schemes for
UPS grounding require grounded-wye service. The UPS system requires a bypass neutral for
sensing and monitoring the quality of the bypass input. If the building service is straight
delta or corner-grounded delta, contact your Liebert representative for details of t he Artificial
Neutral or Isolated Neutral kits for the System Control Cabinet.

• What a re the UPS input and output voltages? Systems with 480 VAC input and output have
significantly different needs t han systems with 208/208 VAC.

• W hat is the connectedload? Does the critical load consist of one or more Power Distribution
Units (PDUs)? Dothe PDUs have isolation transformers?

The following sections discuss recommended grounding procedures for various system configura­tions.

NOTE

Some UPS modules are equipped with input isolation transformers.
However, these transformers have noeffect upon any system grounding
considerations. These modules will be grounded e xactly as shown in the
following examples.

14 Configuring Your Neutral and Ground Connections

7.1 Preferred Grounding Configuration, 480 or 600 VAC Input and Output, Isolated
Power Distribution Units, Wye-Connected Service

Figure 3 Preferred Grounding Configuration, 480 or 600 VAC Input and Output

The most-common configuration of Series 600T U PS Multi-Module Systems is wit h 480 VAC
input, 480 VAC output, and a connected load consi sting of multiple Power Distribution Units
(PDUs) w ith isolation transformers in the PDUs to produce 208 VAC. F or Canadian customers,
the UPS modules usually have 600 VAC input and output. T he same principles apply ifthe con­nected load is an isolation transformer feeding various loads. Figure 3 above shows a typical
installation. The Maintenance Bypass Switchgear is shown separately for clarity, but is usually
contained withinthe System Control Cabinet (SCC).

Notice that the UPS module inputandthe system bypassinput are connected to a grounded-wye
service. In this configuration, the UPS module is not considered a separately derived source.

All of the UPS moduleoutput neutralsaresolidlyconnectedto the SCC neutral.TheSCC neutral
is so lidly connected to the building service ne utral, which is bonded to the grounding conductor at
the service entrance equipment.

The isolation transformers in the PDUs can be considered separately derived sources. Therefore
the PDU neutrals should be bonded to t he PDU g rounding conductor and connected to a local
grounding electrode in compliance with NEC 250-26.

NOTE

Impedance-grounded wye sources require an Isolated Neutral Kit in
addition to the grounding and neutral conductors shown above.

Configuring Your Neutral and Ground Connections 15

7.2 Grounding Configuration, 480 or 600 V AC Input and Output, Delta Source

Figure 4 Grounding Configuration with Ungrounded Delta Source Input

As previously mentioned, Series 600T UPS systems requirea bypass input n etrual for sensing
and monitoring. With a wye-connected input source, the installer should always connect the
building service neutral to the System Control Cabinet (SCC) output neutral to achieve this.
When the building service is delta-c onnected, however, the installer must take special steps to
ensure reliable UPS functioning.

If building service is ungroundeddelta (andthereisnointenttooperatewithonecornerofthe
delta grounded, either on purpose or accidentally), the SCC requires the Series600T Artificial
Neutral Kit for proper operation. This kit uses a resistor network to create a reference point for
the bypass input. In this case, the SCC output neutral must be bonded to the SCC ground.

If the building service is corner-grounded delta or an Impedance-grounded wye, theSCC requires
the Isolated Neutral Kit. This kit uses control isolation transformers to create a referen ce point.
For this application, the SCC output neutral must notbe bonded to the SCC ground.

NOTE

The Artificial Neutral Kit introduces a maximum currentof 0.3 amps to
ground. Take care to ensure that this does not interfere with the operation
of any upstream ground-fault detection devices.

16 Configuring Your Neutral and Ground Connections

7.3 Preferred Grounding Configuration with Power-Tie Switchgear

Figure 5 Preferred Grounding Configuration, Power-Tie Systems

Multi-Module Systems can beused with Power-Tie switchgear to providedual critical load busses.
The Power-Tie switchgear permits transferring critical loads from one critical bus to the other so
that one UPS system and associated breakers can be de-energized for maintenance. Certain con­figurationsof Power-Tieequipmentalso permit the operator to c ontinuously parallel the output of
both UPS systems.

In tied systems, each SCC must have its neutral solidly connected to the Power-Tie switchgear
neutral. The UPS modules, as usual, must have their output neutrals solidly connected to their
respective SCC neutrals. There shouldnot be a connection between the service entrance neutral
and either the SCC or module neutrals.

NOTE

It is essential to run a neutral connection between t he tie switchgear and
bothSCCsasshownintheillustrationabove.

Configuring Your Neutral and Ground Connections 17

7.4 Grounding Configurations, Battery Systems

Figure 6 Battery Cabinet Grounding Configuration

Large, open-rack battery systems are normally either locally grounded or left ungrounded,
depending on local code requirements.

Battery cabinet systems, on the other hand, should be grounded to the UPS module ground bus.
The figure above illustrates how a simple one-cabinet system would be grounded. For systems
with multiple cabinets, the same configuration would apply. However, for simplicity the installer
can connect all the battery cabinet grounds for a particular module together and run a single
ground conductor to that UPS module ground.

8.0 WIRING CONSIDERATIONS

WARNING

!

ALL POWER CONNECTIONS MUST BE COMPLETED BY A
LICENSED ELECTRICIAN THAT IS EXPERIENCED IN WIRING
THIS TYPE OF EQUIPMENT. WIRING MU S T BE INSTALLED IN
ACCORDANCE WITH ALL APPLICABLE NATIONAL AND LOCAL
ELECTRICAL CODES. IMPROPER WIRING MAY CAUSE
DAMAGE TO THE EQUIPMENT OR INJURY TO PERSONNEL.

VERIFY THAT ALL INCOMING HIGH AND LOW VOLTAGE
POWER CIRCUITS ARE DE-ENERGIZED AND LOCKED OUT
BEFORE INSTALLING CABLES OR MAKING ANY ELECTRICAL
CONNECTIONS.

Refer to Appendix A - Site Planning Data a nd installation drawings (Figure 8 through
Figure 58). Determine AC currents for your system (kVA, voltage, a nd options). Also refer to

equipment nameplate for the model number, rating, and voltage. Refer to Table 1 and Table 2
for wire termination data.

NOTE

Use 75°C copper wire. Selectwire s ize based on the ampacities in Table 3
of t his manual, a reprint of Table 310-16 and associated notes of the
National Electrical Code (NFPA 70).

CAUTION

!

The weight of power cables must be adequately supported to
avoid stress on bus bars and lugs. In addition to weight su pport,
the followingrestrainingmethod is recommended to controlcable
movement during external fault conditions: Wrap line cables
together at 6 inches and 12 inches from the terminals with 5
wraps of 3/8 inch nylon rope or equivalent (tensile strength of
2000 po unds). Support remainder of cable with 5 wraps every 6
inches or 1 wrap every 1 inch.

Wiring Considerations 19

8.1 Power Wiring

1. Power wiring must be run in individual, separate conduits or cable trays. Refer to the Outline
and Terminal Details drawings (Figure 8 to Figure 15 and Figure 29 to Figure 32)for
locations of the various power connections within the UPS and SCC. In particular, note the
location of the rectifier input power connections.

CAUTION

!

Power and control wiring must be separated!

2. Observe local, state and national electrical codes. Verify utility power and its overcurrent
protection rating will accommodate the UPS input rating, including battery recharging.

3. A safety ground wire must be run from building ground to ground point in the UPS Module
Cabinets, the Sy stem Control Cabinet, and thePower-Tie Cabinet(if applic able). See Sections

7.1 through 7.4. The grounding conductor shall comply with the following conditions of
installation:

a. An insulated grounding conductor must be sized in accordance with th e NEC and local

codes. It must be green (with or without one or more yellow stripes) and be installed as
part of the branch circuit that sup plies the unit or system.

b. The grounding conductor described above is to be grounded to earth at the service

equipment or, if supplied b y a separately derived system, at the supply transformer or
motor-generator set in accordance with the instructions in Section 7 of this Manual.

c. The attachment-plug receptacles in the vicin ity of the u nit or system are all to be of a

grounding type, and the g rounding conductors serving these receptacles are to be
connected to earth ground at the service equipment.

4. When possible, input to th e UPS and byp ass should be fo ur wire plus ground. When input is
straight delta, the UP S artificial neutral kit should be orde red. When input is corner­grounded delta, the isolated neutral kit should b e ordered.

5. Observe clockwise phase rotation of all power wiring. Phase A leads Phase B leads Phase C. A
qualified electrician should check the phase rotation.

6. Power cables must be rated for le ss than 2 volts line drop at maximum rated system current.

7. If site equipment includes a backup generator and automatic transfer switch(es), consult the
manufacturers of those devices for information on sizing and interfacing to the UPS system.

8. The installing contractor can remove the access plates from the left and right side of the cable­access area in the top of the UPS in order to c ut entry holes for conduit. For units that also
have bottom cable access, there is a third access p late on the right side of the module.

CAUTION

!

After cutting holes in the access plates,be certain that no foreignmatter (metal
shavings, sawdust, insulation or wire fragments, etc.) remains inside the UPS.
Likewise be certain to block any “extra” holes in the plates through which
foreign matter could later enter the UPS.

20 Wiring Considerations

8.2 Control Wiring

Control wiring must be stranded and tinned and run in individual separate steel conduits. Con­trol wiring must be separated from power wiring. In addition, each control wiring cable group
should be run in a separate conduit to minimize control signal interference.

Refer to the Control Connection Locations and Control Wire Lists, Figure 33 through Figure52.
Notice that there are nine cable groups in a typical system:

• Cable group 1 carriessignalsfor the Module BatteryDisconnect.

• Cable group 2 is for the remote communications options: modem, remote terminal and remote
CRT.

• Cable group 3 carriessignals for the Remote Emergency Module Off and Remote Emergency
Power Off.

• Cable group 4 carries signals for the optional Remote Status Panel.

•Cablegroup5isfortheoptionalSiteScansystem.

• Cable group 6 carries signals for the reduced battery charge lim it and the reduced input cur­rent limit.

• Cable gr oup 7 carries signals to and from th e maintenance bypass switchgear.

• Cable groups 20 and 21 carry signals for general housekeeping, modules to SCC.

Other cable groups will be required for other optional equipment. If your system has any installed
options, special wi re lists will be included in your Submittal Drawing Package.Contact your Lie­bert Sales Representative for assistance ifthe submittal drawingshave been lost or misplaced.

Figures AA and BB show the t ypical location of control connections inside the UPS and SCC. The
position of a particular control connection may be different for your system, depending on the
model and the installed options.

NOTE

The UPS control and communication wiring are considered Class 2
circuits by NEC standards. However, NEC Class 1 wiring methods are
required for these circuits to ensure proper operation of the UPS.

Wiring Considerations 21

8.3 Battery Wiring

Power wiring to the Battery Cabinet connects positive, negative, and ground power cables from
the Battery Cabinet to the associated UPS. Connection of the UPS to the Battery Cabinet serves
to both chargeand discharg e the batteries (w he n needed). The batterydisconnect (cir cuit breaker)
requires a control cable. Liebert Battery Cabinets include power and controlcables to join multi­ple cabinets together into a system. Additional (field-supplied) power or control wiring might be
necessary to connect the battery cabinet system to the UPS. Refer to Figure 16 through

Figure 18.

DANGER

!

A BATTERY INTERCELL CONNECTION ON EACH TIER OF THE
LIEBERT BATTERY CABINET IS DISCONNECT ED FOR SAFETY
DURING SHIPMENT. DO NOT COMPLETE THESE
CONNECTIONS. THE LIEBERT GLOBAL SERVICES
REPRESENTATIVE WILL COMPLE TE THESE CONNECTIONS
AS PART OF START-UP. AN IMPROPERLY INSTALLED UNIT
CAN RESULT IN INJURY TO PERSONNEL OR DAMAGE TO
EQUIPMENT.

CAUTION

!

Be sure polarity is correct when wiring the Battery Cabinetto the
connected equipment (positive to positive; negative to negative).
If polarity is not correct, fuse failures or equipment damage can
result.

CAUTION

!

DC power cables should be installed in conduit with conductors
in matched pairs (positive and negative).

NOTE

A Liebert Battery Specialist can perform a detailed inspection of the entire
battery system to ensure it meets current IEEE standards. This inspection
service is recommended because batteries are a very critical part of the UPS
system.

12.0 APPENDIX A-SITE PLANNING DATA

500-750kVA Multi-Module Systems

12.1 Notes

1. Nominal rectifier AC inputcurrent (considered continuous) is basedon full rated output load.
Maximum currentincludes nominal input currentand maximum battery recharge current
(considered noncontinuous). Continuous and noncontinuous current limit are defined in NEC

100. Maximum input current is controlled by current limit setting which is adjustable. Values
shown are for maximum setting of 125%. Standard factory setting is 115%.

2. Nominal AC output current (considered continuous) is based on full rated output load.
Maximum current includes nominal output current and overload for 10 minutes.

3. Bypass AC input current (considered continuous) is based on full r ated output load.

4. Feeder protection (by others in external equipment) for rectifier AC input and bypass AC
input is recommended to be provided by separate overcurrent protection devices.

5. UPS o utput load cables must be run in separate conduit from input cables.

6. Power cable from module DC bus to battery should be sized for a total maximum 2.0 volt line
drop (measured at the module)at maximum discharge current.

7. Grounding conductors to be sized per NEC 250-122. Neutral conduct ors to be sized for full
capacity forsystems with 4-wire loads and half capacity for syste ms with 3-wire loads. NOTE:
A neutral conductor is required from each Multi-Module Unit output to the System Control
Cabinet.

8. Rectifier AC Input: 3-phase, 3-wire, plus ground
ACOutput,SCCtoLoad:3-phase,3or4-wire,plusground
Bypass AC Input: 3-phase, 3 or 4-wire, plus ground
Module DC Input fr om Battery: 2-wire, (positive and negative)

9. All wiring is to be in accordance with National and Local Electrical Codes.

10. Minimum clearance is 2 feet above U PS.

11. Top or bo ttom cable entr y through removable access plates. Cut plate to suit con duit size.

12. Control wiring and power cables must be run in separate conduits. Control wiring must be
stranded tinned conductors.

13. 7% maximum input harmonic current and 0.92 lagging in put power factor at full load with 6­pulse rectifier and optional input filter (4% with 12-pulse rectifier and input filter).
30% maximum input harmonic current and 0.85 lagging input power factor at full load
without optional input filter (9% with 12-pulse rectifier).

14. Dimensions and weights do not include the System Control Cabinet required for Multi­Module Systems.
