IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS

This manual contains important instructions that should be followed during installation of your Series 610 UPS and batteries.

WARNING

Exercise extreme care when handling UPS cabinets to avoid equipment damage or injury to personnel. The UPS module weight ranges from 16,555 to 17,400 lbs. (7509 to 7893kg), including input transformer. The battery cabinets weigh from 3060 to 5300 lbs. (1388 to 2404kg).

Locate center of gravity symbols and determine unit weight before handling each cabinet. Test lift and balance the cabinets before transporting. Maintain minimum tilt from vertical at all times.

Slots at the base of the modules and battery cabinets are intended for forklift use. Base slots will support the unit only if the forks are completely beneath the unit.

System Control Cabinets (SCCs) have holes intended for rigging bars or chains. Prevent chains or cables from contacting cabinet by using spreader bar and adequate padding.

Follow all battery safety precautions when installing, charging or servicing batteries. In addition to the hazard of electric shock, gas produced by batteries can be explosive and sulfuric acid can cause severe burns.

In case of fire involving electrical equipment, use only carbon dioxide fire extinguishers or those approved for use in fighting electrical fires.

Extreme caution is required when performing maintenance. Be constantly aware that the UPS system contains high DC as well as AC voltages. Check for voltage with both AC and DC voltmeters prior to making contact.

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

WARNING

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

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

This equipment contains several circuits that are energized with high voltage. Only test equipment designed 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 the power is turned Off, dangerously high potential electric charges may exist at the capacitor banks and at the batteries.

All power and control wiring should be installed by a qualified electrician. All power and control wiring must comply with the NEC and applicable local codes.

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 from direct contact with the floor (earth ground).

One person should never work alone, even if all power is removed from the equipment. A second person should be standing by to assist and summon help in case an accident should occur.

CAUTION

This unit complies with the limits for a Class A digital device, pursuant to Part 15 Subpart J of the FCC rules and EN550022. These limits provide reasonable protection against harmful interference in a commercial environment. This unit generates, uses and radiates radio frequency energy and, if not installed and used in accordance with this instruction manual, may cause harmful interference to radio communications. Operation of this unit in a residential area may cause harmful interference that the user must correct at his own expense.

NOTE

Materials sold hereunder cannot be used in the patient vicinity (i.e., cannot be used where UL 60601-1, cUL 60601-1 or IEC 60601-1 is required). Medical Applications such as invasive procedures and electrical life support equipment are subject to additional terms and conditions.

1.0 INSTALLATION CONSIDERATIONS

Install your Series 610 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 will be voided unless system start-up is performed by a Liebert authorized representative. Contact your local Liebert sales representative or Liebert Global Services at 1-800-LIEBERT to arrange for system start-up.

CAUTION

Read this manual 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 Figures 14 through 44 and Appendix A.

2. Be certain that the floor at the final equipment location and along the route (inside the facility) to the installation site can support the cabinet weight and the weight of any moving equipment. The modules weigh from 16,555 to 17,400 lbs. (7509 to 7893kg). The battery cabinets weigh from 3060 to 5300 lbs. (1388 to 2404kg). The System Control Cabinets weigh from 1000 to 5850 lbs. (454 to 2653kg). Refer to Appendix A. For switchgear weights, refer to your submittal package.

WARNING

Locate center of gravity symbols and determine unit weight before handling cabinet.

3. Plan the route to ensure that the unit can move through all aisleways and doorways and around corners without risking damage. If the modules and batteries must be moved by elevator, check the size of the door openings and the weight-carrying capacity of the elevator.

4. Refer to information later in this manual regarding the optional battery cabinets and Transformer Cabinets. Observe all battery safety precautions when working on or near

the battery.

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

6. Recommended ambient operating temperature is 77°F (25°C). Relative humidity must be less than 95%, non-condensing. Note that room ventilation is necessary, but air conditioning may not be required. Maximum ambient operating temperature is 104°F (40°C) without derating. The batteries should not exceed 77°F (25°C). At elevations above 4000 ft. (1219m), temperature derating may be required for full power output—consult your Liebert sales representative or call 1-800-LIEBERT.

7. Even though your Liebert UPS unit is at least 92-94% efficient, the heat output is substantial. For more specific information, see Appendix A. Be sure environmental conditioning systems can accommodate this BTU load, even during utility outages.

8. The installer should attempt to balance the load between the three output phases. The UPS will operate safely with an unbalanced load, but will give optimum performance if the three output phases are loaded within 20 percent of each other.

9. During normal UPS operations, short-term overload current demand from the bypass source may reach 10x the UPS output current rating. This overload current demand may be caused by the magnetizing inrush current of one or more downstream transformers or faults on downstream branch circuits. The instantaneous trip point(s) of the upstream bypass feeder breaker(s) must be set to support these temporary overloads. The magnitude of short-term overload bypass current demand is typically six to eight times the UPS current rating, but must be determined by analysis on a per-site basis. This analysis, generally known as an End-to-End Fault Coordination Study, must be done by a Registered Professional Engineer experienced in this activity and familiar with local codes and related requirements.

Installation Considerations

NOTE

While Liebert can provide typical guidelines, the responsibility for the proper breaker trip settings outside of the Liebert-manufactured UPS equipment resides with the owner. Contact Liebert Global Services at 1-800-LIEBERT for further details.

Page 8

10. A breaker coordination study should be performed to ensure proper handling of fault currents.

NOTE

The instantaneous trip setting of the breaker feeding the SCC bypass input should be high enough to accommodate short-duration overloads. The bypass static switch inside the SCC can draw up to 10 times the system’s rated current for up to three cycles.

1.1 Types of System Control Cabinets

1. SCCT is a stand-alone cabinet containing system control logic for up to six UPS modules, static bypass switch, manually operated disconnects for the static bypass switch, and two motoroperated system breakers. The SCCT is painted the same color as the Liebert UPS, but does not match the sheet metal style of the UPS. For SCCT dimensions, refer to Table 8.

2. SCCI has the system control logic, circuit breakers and static bypass switch integrated into a switchboard cabinet manufactured by others.

3. SCCC is an integrated configuration like the SCCI with the static bypass switch rated for continuous duty.

Installation Considerations

Page 10

2.0 UNLOADING AND HANDLING

UPS modules are shipped in split cabinets to allow ease of handling. Because the weight distribution in the cabinets is uneven, use extreme care during handling and transport. Your installation may also include battery cabinets and a System Control Cabinet.

NOTE

It is very important that the shipping split sections are matched up to their proper mates, as identified by the shipping split labels.

Integrated SCC/Switchgear will also be shipped in sections, and require proper match up of sections, as identified by labels and drawings.

WARNING

Exercise extreme care when handling UPS cabinets to avoid equipment damage or injury to personnel. The UPS module weight ranges from 16,555 to 17,400 lbs. (7509 to 7893kg). Battery cabinets weigh from 3060 to 5300 lbs. (1388 to 2404kg).

Locate center of gravity symbols before handling cabinet. Test lift and balance the cabinet before transporting. Maintain minimum tilt from vertical at all times.

Slots at the base of the modules and battery cabinets are intended for forklift use. Base slots will support the unit only if the forks are completely beneath the unit.

System Control Cabinets (SCCs)/Switchgear have holes intended for rigging bars or chains (see your submittal package for switchgear drawings). Prevent chains or cables from contacting cabinet by using spreader bar and adequate padding.

Unloading and Handling

To reduce the possibility of shipping damage, cabinets are shored with 2-by-4 bracing, secured with screw-type nails. This shoring must be carefully removed prior to unloading.

CAUTION

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

Page 11

3.0 INSPECTIONS

3.1 External Inspections

1. While the UPS system is still on the truck, inspect the equipment and shipping container(s) for any signs of damage or mishandling. Do not attempt to install the system if damage is apparent. If any damage is noted, file a damage claim with the shipping agency within 24 hours and contact Liebert Global Services at 1-800-LIEBERT to inform them of the damage claim and the condition of the equipment.

2. Compare the contents of the shipment with the bill of lading. Report any missing items to the carrier and to Liebert Global Services immediately.

3. Remove equipment from truck using appropriate handling precautions and equipment.

4. Each shipping section will be identified by a label located on the plywood piece that is used to cover the end sections of each shipping split, or on the pallet that the equipment is shipped on. Before removing wood shipping covers, identify the individual pieces and group together the shipping sections of each individual UPS module.

5. Locate cabinet keys. Depending upon equipment type, the keys will either reside in a plastic bag marked “Packing slip enclosed” on a front door of the cabinet, or be taped to a circuit breaker handle protruding through the front of the cabinet.

3.2 Internal Inspections and Shipping Material Removal

1. Verify that all items have been received.

2. If spare parts were ordered, verify arrival.

3. Open doors and remove cabinet panels to check for shipping damage to internal components.

4. Check for loose connections or unsecured components in the cabinet(s).

5. Check for installation of circuit breaker line safety shields. There should be no exposed circuit breaker terminals when the cabinet doors are opened.

6. Check for any unsafe condition that may be a potential safety hazard.

7. UPS modules are shipped with internally mounted shipping brackets. The shipping brackets (painted orange) must be removed from the rear (remove rear panels). The installer must remove the orange shipping brackets before final equipment placement, particularly if rear access will be restricted.

Inspections

CAUTION

Failure to remove orange shipping brackets from transformers may cause restricted airflow within the UPS. This could cause overheating or reduction of UPS capacity. In some cases, it could cause damage to the UPS module, and such damage would not be covered under the factory warranty. If you foresee a situation where the UPS will be relocated in the near future, the brackets should be removed and stored elsewhere until they are needed.

8. Remove wood shipping split covers. These covers consist of a 2-by-4 frame covered with plywood. The 2-by-4 frame is attached using lag bolts screwed into the wood from the inside of the cabinet.

9. Check the nameplate/ratings label on the inside of the Module and SCC control section doors to verify that the model numbers correspond with those specified. Record the model numbers and serial numbers in the front of this installation manual. A record of this information is necessary should servicing be required.

Use a suitable material handling device to move the cabinet to its final location. Exercise extreme care because of the uneven weight distribution. Carefully lower the cabinet to the floor.

2. Referring to Shipping Split Detail (Figure 18), and any other drawings that are associated with switchgear, set cabinets in final position, preparatory to reconnection of shipping split power and control wiring/bus.

3. Verify that the UPS system is installed in a clean, cool and dry location.

4. Installation and serviceability will be easier if adequate access is provided on all sides of the equipment, but only front access is required.

a. Verify that there is adequate clearance to open cabinet doors—4 ft. (1.2m) is recommended.

NEC requires sufficient clearance in front of the equipment to fully open all doors without restriction. See drawings and local codes. SCCT requires front and rear or one-side access for installation and maintenance.

b. Verify that there is adequate area in front of circuit breakers to perform maintenance. Check

installation drawings for location of breakers. Check with local codes.

c. Verify that there is adequate clearance above all cabinets to allow exhaust air to flow without

restriction. The minimum clearance is 2 ft. (0.6m), unobstructed by conduit or any other items. Liebert recommends against using upflow air conditioning systems or any system that blows air down onto the top of the modules.

5. Align the UPS cabinet, battery cabinets (if used) and optional transformer and maintenance bypass cabinets, as shown in the Outline Drawing (Figure 14) and your submittal package.

6. Referring to Shipping Split Details (Figure 18) and your submittal package for SCC/Switchgear drawings), connect cabinets together mechanically.

7. Referring to Shipping Split Details (Figure 18) and your submittal package for SCC/Switchgear drawings), connect intercabinet ground straps, power wiring and bus interconnects. Internal control connections should be left disconnected for later installation by Liebert LGS Customer Engineers.

5.0 BATTERY INSTALLATION

5.1 Battery Safety Precautions

Servicing of batteries should be performed or supervised by personnel knowledgeable of batteries and the required precautions. Keep unauthorized personnel 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 must be recycled rather than discarded.

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

Do not install any batteries that are cracked, leaking or show other signs of damage. Contact Liebert Global Services or your local Liebert representative.

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

• Remove watches, rings and other metal objects.

• Use tools with insulated handles.

• Wear rubber gloves and boots.

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

• Disconnect charging source prior to connecting or disconnecting battery terminals.

• 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:

Battery Installation

• DO NOT SMOKE when near batteries.

• DO NOT cause flame or spark in battery area.

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

• After replacing battery jars in a battery cabinet, replace the retaining straps that hold the jars in place on the shelves. This will limit accidental movement of the jars and connectors should the cabinet ever need to be repositioned or relocated. Regular maintenance of the battery module is an absolute necessity. Periodic inspections of battery and terminal voltages, specific gravity and connection resistance should be made. Strictly follow the procedures outlined in the battery manufacturer’s manual, available on the manufacturer’s Web site.

5.2 Battery Safety Precautions in French Per CSA Requirements

Instructions Importantes Concernant La Sécurité Conserver Ces Instructions

AVERTISSEMENT

Respecter toutes les consignes de sécurité applicables à l'installation, le chargement ou l'entretien des batteries. En plus du danger de chocs électriques, le gaz produit par les batteries peut exploser dégageant de l'acide sulfurique qui peut entraîner de très graves brûlures.

Toute opération d'entretien/réparation des batteries doit être exécutée ou supervisée par un personnel qualifié dans le domaine et en prenant toutes les précautions nécessaires. Tenir le personnel non autorisé à l’écart des batteries.

ATTENTION

Les batteries acide-plomb contiennent des substances toxiques dangereuses. Les batteries doivent être manipulées, transportées et recyclées ou jetées conformément à la réglementation en vigueur aux niveaux national et local. Le plomb étant toxique, les batteries acide-plomb doivent être recyclées et non jetées.

Ne pas ouvrir ni endommager la ou les batteries. Les électrolytes diffusés sont dangereux pour la peau et les yeux. Ils sont toxiques. Ne pas jeter la ou les batteries dans le feu. Risque d'explosion.

Ne jamais installer de batteries avec des cellules fissurées ou endommagées. Contacter Liebert Global Services ou le représentant agréé Liebert local.

Une batterie peut poser un risque de choc électrique et de courant élevé provoqué par un court-circuit. Respecter les précautions suivantes lors de travaux sur les batteries :

• Enlever montres, bagues ou autres objets métalliques.

• Utiliser des outils dont les poignées sont isolées.

• Porter des gants et des bottes en caoutchouc.

• Ne pas poser d'outils ou d'objets métalliques sur les batteries.

• Déconnecter la source de chargement avant de connecter ou de déconnecter les bornes de batterie.

• Vérifier que la batterie n'a pas été mise à la masse par inadvertance. Si elle est mise à la masse, éliminer la source de masse. Tout contact avec des composants de batterie mise à la masse peut entraîner un choc électrique. Éliminer le risque de chocs électriques potentiels en retirant les sources de masse avant l'installation et la maintenance.

Les batteries acide-plomb peuvent représenter un risque d'incendie puisqu'elles génèrent de l'hydrogène. Respecter les procédures suivantes :

• NE PAS FUMER près des batteries.

• NE PAS générer de flammes ou d'étincelles près des batteries.

• Éliminer l'électricité statique du corps avant de manipuler les batteries en touchant d'abord une surface métallique mise à la terre.

L’électrolyte est un acide sulfurique dilué qui est dangereux au contact de la peau et des yeux. Ce produit est corrosif et aussi conducteur electrique. Les procédures suivantes devront être observées :

• Porter toujours des vêtements protecteurs ainsi que des lunettes de protection pour les yeux.

• Si l’électrolyte entre en contact avec la peau, nettoyer immédiatement en rincant avec de l’eau.

• Si l’électrolyte entre en contact avec les yeux, arroser immédiatement et généreusement avec de l’eau. Demander pour de l’aide médicale.

• Lorsque l’électrolyte est renversée, la surface affectée devrait être nettoyée en utilisant un agent neutralisant adéquat. Une pratique courante est d’utiliser un mélange d’approximativement une livre (500 grammes) de bicarbonate de soude dans approximativement un gallon (4 litres) d’eau.

5.3 Battery Cabinets

Optional battery cabinets are available from Liebert and other qualified vendors. Consult your submittal package for details.

Several models of optional battery cabinets with varying run times are available. Each model is 78" (1981mm) high and has forklift slots. Refer to the Battery Cabinet submittal drawings if a battery cabinet is to be used. 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. Handling. The battery cabinet weighs from 3060 to 5300 lbs. (1388 to 2404kg). Forklift slots are provided for ease of handling.

2. Cabinet Inspection. Remove all panels and visually inspect the batteries, bus connections, and cabinet for any damage. If any foam blocks were placed between shelves to restrain movement during shipment, remove them now. Exercise caution—voltage is present within the battery cabinet even before installation. If there are signs of damage, do not proceed. Call Liebert Global Services at 1-800-LIEBERT.

3. Battery Storage. The batteries used in the battery cabinet retain their charge well. The batteries can be stored indoors in a temperature-controlled environment, for up to six months without any appreciable deterioration. Self-discharge rate of the batteries is approximately 3% per month when the batteries are stored in temperatures of 59°F to 77°F (15-25°C). If the battery cabinet must be stored for longer than six months, contact Liebert Global Services. The battery cabinet should never be stored outdoors or on a loading dock.

4. Installation. Battery cabinets can be located conveniently next to each UPS module. The frontaccess-only-design eliminates side and rear service clearance requirements.

5. Reinstallation. If at any time it becomes necessary to move the battery cabinet to another location, contact Liebert Global Services to inspect the internal battery hold-down straps.

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

7. 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 3 ft. (1m) of clearance at the front of the cabinet when operating. Side and rear panels do not require service clearance.

8. Side Panels. To connect battery cabinets together, remove the protective side panels by removing the retaining screws that hold the side panels in place.

9. Cables. Multiple battery cabinets may be bolted together in a daisy-chain configuration. Cables for this setup may be run between paralleled battery cabinets through cutouts in the top of the cabinets, eliminating the need for external conduit runs. Route cables before moving cabinets into final position for bolting together. Low voltage control wiring must be kept separate from the power wiring. Remove top panels for access, if required. No top or bottom entry cables are required, except for remotely located cabinets, which require conduits. Refer to your submittal drawings for instructions on wiring cabinets in parallel.

Battery Installation

NOTE

The 1000kVA UPS module is approximately 2 to 6 in. (51-152 mm) deeper than the battery cabinet and is not designed to bolt directly to it.

10. Grounding. The battery cabinets have ground studs near the busbar connections. Use an equipment grounding conductor to connect the lugs of the cabinets together and to connect the cabinets to the ground busbar in the UPS module.

Page 16

5.4 Open-Rack Batteries

When batteries other than Liebert battery cabinets are used, a remote battery disconnect switch with overcurrent protection is required per the National Electrical Code. Refer to Required Battery Disconnect Rating in the site planning data tables in Appendix A for recommended overcurrent protection ratings. Contact your Liebert sales representative for more information.

1. Install battery racks/cabinets and batteries per manufacturer’s installation and maintenance instructions.

2. Verify battery area has adequate ventilation and battery operating temperature complies with manufacturer’s specification. Installations using vented lead-acid batteries MUST have adequate ventilation to remove explosive gases per local and national codes.

3. Low voltage control wiring must be kept separate from power wiring and run in separate conduits.

4. Ensure that battery racks are properly grounded according to code requirements in your area.

If you have any questions concerning batteries, battery racks or accessories, contact your local sales representative or Liebert Global Services at 1-800-LIEBERT.

CAUTION

Cables between batteries and the UPS modules should be run in matched pairs, positive-with-negative, within each conduit or cable run. Grouping like-polarity cables together (i.e., positive-with-positive and negative-with-negative) can cause stress or damage to the cables, conduit or buswork.

Configuring Your Neutral and Ground Connections

6.0 CONFIGURING YOUR NEUTRAL AND GROUND CONNECTIONS

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 anything other than a grounded wye system (corner grounded delta or impedance grounded wye), contact your Liebert representative for details about the Isolated Neutral kits for the System Control Cabinet and UPS modules.

WARNING

If the building service feeding the UPS is any configuration other than those mentioned above, contact your Liebert representative or Liebert Global Services immediately.

A Power-Tie or distributed redundant system has different grounding requirements from standalone UPS modules. If using one of those systems, refer to Liebert’s Power-Tie configuration user manual, SL-30030.

• What are the UPS input and output voltages? Systems with 480 VAC input and output have significantly different needs from systems with 208/208 VAC.

• What is the connected load? Does the critical load consist of one or more Power Distribution Units (PDUs)? Do the PDUs have isolation transformers?

Proper grounding should be based on NEC Section 250, but safe and proper equipment operation requires further enhancements. The following pages detail Liebert’s recommendations for grounding various system configurations to ensure optimal UPS system performance.

NOTE

Some UPS modules are equipped with input isolation transformers. However, these transformers have no effect upon any system grounding considerations. These modules will be grounded exactly as shown in Figures 4 through 10.

CAUTION

The UPS ground lug must be solidly connected to the service entrance ground by an appropriately sized wire conductor per NEC Article 250. Each conduit or raceway containing phase conductors must also contain a ground wire, both for UPS input and output, which are solidly connected to the ground terminal at each termination point. Conduit-based grounding systems tend to degrade over time. Therefore, using conduit as a grounding conductor for UPS applications may degrade UPS performance and cause improper UPS operation.

Page 18

Configuring Your Neutral and Ground Connections

6.1 Preferred Grounding Configuration, Wye-Connected Service

The most common configuration of Series 610 UPS Multi-Module Systems is with 480 VAC input, 480 VAC output and a connected load consisting of multiple Power Distribution Units (PDUs) with isolation transformers in the PDUs to produce 208 VAC. For Canadian customers, the UPS modules usually have 600 VAC input and output. The same principles apply if the connected load is an isolation transformer feeding various loads. Figure 4 shows a typical installation. The Maintenance Bypass Switchgear is shown separately for clarity, but may be contained within the System Control Cabinet (SCC)/switchgear.

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

All of the UPS module output neutrals are solidly connected to the SCC neutral. A parity-sized neutral is recommended between the UPS module and the SCC for best system performance. The SCC neutral is solidly connected to the building service neutral, which is bonded to the grounding conductor at the service entrance equipment.

The isolation transformers in the PDUs are considered a separately derived source. Therefore the PDU neutral should be bonded to the PDU grounding conductor and connected to a local grounding electrode in compliance with NEC 250-26. (PDUs are connected to the critical load output of the SCC, but are not shown in Figure 4 for clarity.)

Figure 4 Preferred grounding configuration, wye-connected service

UPS MODULE N, N=2-6

NOTE

Impedance-grounded wye sources require an Isolated Neutral Kit in addition to the grounding and neutral conductors shown above—see 6.5 - Grounding Configuration, Corner- Grounded Delta or Impedance-Grounded Wye.

NOTE

If there is a 4-pole Automatic Transfer Switch (ATS) between the service entrance and the UPS, this configuration cannot be used. Refer to 6.2 - Alternate Grounding Configuration, Wye- Connected Service or 6.3 - Preferred Grounding Configuration With Isolated Bypass to determine a suitable configuration.

Page 19

Configuring Your Neutral and Ground Connections

6.2 Alternate Grounding Configuration, Wye-Connected Service

This configuration must NOT be used when single-phase loads are directly connected to the UPS. The alternate configuration is similar to that shown in 6.1 - Preferred Grounding Configuration,

Wye-Connected Service, except that the service entrance neutral is not brought into the UPS module. In this configuration, the UPS output transformer is considered a separately derived source. The UPS module neutral is bonded to the UPS ground, which is connected to a local grounding electrode in accordance with NEC 250-26.

Please note that this configuration represents a price/performance trade-off. Whenever the UPS module transfers to or from bypass, two AC sources (input and bypass) are briefly connected together and circulating current must flow. In the previous configuration, the current flows through the neutral conductor. In this configuration, the current flows through the ground path, possibly tripping ground fault interrupters (GFIs) and distorting the bypass waveform reference.

Proper adjustment of ground fault interrupters is necessary to avoid unwanted tripping.

Figure 5 Alternate grounding configuration, wye-connected service

This configuration is reserved for applications that meet all the following criteria:

• The facility has wye-connected service.

• The module rectifier input and bypass input are fed from the same source.

• The connected load is strictly 3-wire (such as one or more PDUs) and does not require a neutral from the UPS.

• Special precautions are taken to prevent tripping the ground fault interrupters. The time delay should be set to at least 0.2 seconds to prevent tripping when the UPS performs a transfer or retransfer operation.

CAUTION

Failure to properly set the ground fault interrupters could cause loss of power to the critical load.

Page 20

Configuring Your Neutral and Ground Connections

6.3 Preferred Grounding Configuration With Isolated Bypass

Another configuration in this power range is the Multi-Module System with 480 or 600 VAC input, 208 VAC output, a Bypass Isolation Transformer and a connected load consisting of multiple distribution panelboards or switchboards. Figure 6 shows a typical installation.

The Bypass Transformer provides isolation and may step down the voltage to the bypass input. The Bypass Transformer and the SCC together constitute a separately derived system, since there is no direct electrical connection between the input (service entrance) circuit conductors and the output circuit conductors.

NOTE

Figure 6 shows a wye-connected source, but the same grounding scheme would apply for a delta source at the service entrance.

The bonding of the neutral to the grounding conductor can theoretically be done at either the SCC or the Bypass Transformer. However, we recommend bonding at the Bypass Transformer because the UPS module will sometimes be powered down for maintenance and its output transformer will be out of the circuit. The neutral should be bonded to ground and a local grounding electrode should be installed at the Bypass Transformer, per NEC 250-30.

Figure 6 Preferred grounding configuration with isolated bypass

Features of this configuration include:

• The UPS receives its bypass neutral from the Bypass Transformer

• The output is isolated from the input circuit conductors, and

• Some amount of common-mode noise attenuation can be obtained for sensitive loads if the UPS module and Bypass Transformer are located close to sensitive loads.

Page 21

Configuring Your Neutral and Ground Connections

6.4 Alternate Grounding Configuration, Non-Isolated

A few applications in this power range have 208 VAC input and output, and a connected load consisting of multiple Power Distribution Units (PDUs), panelboards, switchboards or other items of load equipment which do not have isolation transformers.

Notice in Figure 7 that the UPS system main input and bypass input are connected to a groundedwye service. In this configuration, the UPS system is not considered a separately derived source.

The UPS module output neutral and the load neutral are solidly connected to the building service neutral, which is bonded to the grounding conductor at the service entrance equipment.

Figure 7 Alternate grounding configuration, non-isolated

This arrangement may be used for systems with 208 VAC input and output. However, it does not provide any isolation or common-mode noise attenuation for sensitive loads. For this reason, this configuration is not a preferred installation method.

NOTE

If there is a 4-pole Automatic Transfer Switch (ATS) between the service entrance and the UPS, this configuration cannot be used. Refer to 6.3 - Preferred Grounding Configuration With Isolated Bypass to determine a suitable configuration.

Page 22

Configuring Your Neutral and Ground Connections

6.5 Grounding Configuration, Corner-Grounded Delta or Impedance-Grounded Wye

As previously mentioned, Series 610 SCC requires a bypass input neutral 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 deltaconnected, however, the installer must take special steps to ensure reliable UPS functioning.

If the building service is corner-grounded delta or impedance-grounded wye, the UPS requires the Series 610 Isolated Neutral Kit, as do each of the UPS modules. This kit uses control isolation transformers to create a reference point. For this application, the SCC output neutral must not be bonded to the SCC ground.

Figure 8 Preferred grounding configuration, corner-grounded delta or impedance-grounded wye

Page 23

Configuring Your Neutral and Ground Connections

Figure 9 Preferred grounding configuration, impedance-grounded wye

These configurations have the same restrictions as explained in 6.2 - Alternate Grounding Configuration, Wye-Connected Service, except for the wye input. The UPS input and bypass must be fed

from the same source. The load must be strictly 3-wire. And the GFI time delay should be set to at least 0.2 seconds to prevent tripping during transfer or retransfer operations.

CAUTION

Failure to properly set the ground fault interrupters could cause loss of power to the critical load.

Page 24

Configuring Your Neutral and Ground Connections

6.6 Preferred Grounding Configuration, Battery Systems

Open-rack battery systems, depending on local code requirements and customer preference, are normally:

1. Floating (ungrounded),

2. Center-tapped and floating or

3. Center tapped and grounded. Battery cabinet systems must be connected as floating (ungrounded) systems—Option 1 above.

Center-tapped or grounded battery systems are not possible with battery cabinet systems. Whether the battery system is open-rack or cabinet, the metal rack parts or cabinet must be grounded

to the UPS module ground bus. Figure 10 illustrates how a simple, one-cabinet system would be grounded. For systems with multi-

ple 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 (in the same conduit as the phase conductors).

Figure 10 Preferred grounding configuration, battery systems

Page 25

7.0 WIRING CONSIDERATIONS

WARNING

All power connections must be completed by a licensed electrician experienced in wiring this type of equipment. Wiring must 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 and drawings in 10.0 - Installation Drawings. Determine AC currents for your system (kVA, voltage and options). Also refer to the equipment nameplate for the model number, rating and voltage. For wire termination data, refer to Tables 2 through 4. Consult your facility’s breaker coordination study to ensure proper handling of fault currents.

NOTE

The instantaneous trip setting of the bypass feeder breaker should be high enough to accommodate short-duration overloads. The bypass static switch inside the SCC can draw up to 10 times the system’s rated current for up to three cycles in the event of a downstream fault.

NOTE

Use 75°C copper wire. Select wire size based on the ampacities in Table 5 of this manual, a reprint of Table 310-16 and associated notes of the National Electrical Code (NFPA 70).

Wiring Considerations

CAUTION

The weight of power cables must be adequately supported to avoid stress on busbars and lugs. In addition to weight support, the following restraining method is recommended to control cable movement during external fault conditions:

• Wrap line cables together at 6 and 12 in. (152 and 305mm) from the terminals with five

wraps of 3/8 in. (9.5mm) nylon rope or equivalent (tensile strength of 2000 lbs.; 907kg).

• Support the remainder of the cable with five wraps every 6 in. (152mm) or one wrap every

1in. (25mm).

Page 26

7.1 Power Wiring

1. Power wiring—rectifier input, bypass input, UPS output and battery cables—must be run in individual, separate conduits or cable trays. Refer to the Outline and Bussing Details drawings (Figures 14, 15, 19, 21, 23, 25, 43 and 44) for locations of the various power connections within the UPS and ancillary equipment. 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 the building ground to a ground point in the UPS Module Cabinets, ancillary equipment and the Power-Tie Cabinet (if applicable). See 6.0 - Configuring Your Neutral and Ground Connections. The grounding conductor shall comply with the following conditions of installation:

a. An insulated grounding conductor must be sized in accordance with the 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 supplies the unit or system.

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

or, if supplied by a separately derived system, at the supply transformer or motor-generator set in accordance with the instructions in 6.0 - Configuring Your Neutral and Ground Connections.

c. The attachment-plug receptacles in the vicinity of the unit or system are all to be of a

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

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

5. AC power cables must be rated to meet NEC requirements for voltage drop at the maximum rated system current. DC power cables from the UPS to the battery terminals and return must be sized for less than 2 volts total loop drop at the maximum rated system current.

6. 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.

7. Removable access plates are available for power wiring. Refer to the Outline Drawings for your particular model (Figures 14, 19, 21, 23, 25, 43 and 44).

Wiring Considerations

CAUTION

After cutting holes in the access plates, be certain that no foreign matter (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.

7.2 Control Wiring

Control wiring must be flexible stranded, tinned copper 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.

Wiring Considerations

Refer to the Control Connection Locations and Control Wire Lists, Figures 27 through 42. Notice that there are nine cable groups in a typical system:

• Cable group 1 carries signals for the Module Battery Disconnect.

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

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

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

• Cable group 5 is for the optional SiteScan system.

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

• Cable group 7 carries signals to and from the 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 wire lists will be included in your Submittal Drawing Package. Contact your Liebert Sales Representative for assistance if the submittal drawings have been lost or misplaced.

Figures 27 and 28 show the typical 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.

Page 29

7.3 Battery Wiring

The UPS may be supplied with battery cabinets or a rack-mounted battery system. Power wiring to the battery cabinet connects positive, negative and ground power cables from the bat-

tery cabinet to the associated UPS. Connection of the UPS to the battery cabinet serves to both charge and discharge the batteries (when needed). The battery disconnect (circuit breaker) requires a control cable. Except for interconnect wiring between multiple battery cabinets, power and control cables are field supplied. Refer to Battery Cabinet submittal drawings.

WARNING

A battery intercell connection on each tier of the Liebert battery cabinet is disconnected for safety during shipment. Do not complete these connections. A Liebert Global Services representative will complete 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 cabinet to the connected equipment (positive to positive; negative to negative). If polarity is not correct, fuse failures or equipment damage can result.

CAUTION

Cables between batteries and the UPS should be run in matched pairs, positive-with-negative, within each conduit or cable run. Grouping like-polarity cables together (i.e., positive-with-positive and negative-with-negative) can cause stress or damage to the cables, conduit or buswork.

Wiring Considerations

Call Liebert Global Services to schedule installation check-out, final battery intercell connections and start-up.

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 critical part of the UPS system.

Page 30

8.0 WIRING CONNECTIONS

WARNING

Verify that all incoming high and low voltage power circuits are de-energized and locked out before installing cables or making electrical connections.

All power connections must be completed by a licensed electrician experienced in wiring UPS equipment and in accordance with all applicable national and local electrical codes.

Improper wiring may cause damage to the UPS or injury to personnel.

CAUTION

All shielded cables, non-shielded cables, non-shielded control wires, non-shielded battery breaker control wires and non-shielded remote control wires must be housed in individual, separate, steel conduits. Placing multiple cables in the same conduit with other control or power wiring may cause system failure.

NOTE

Use appropriately sized wire as a grounding conductor. Solid metal conduit is not a suitable ground conductor for UPS systems and could negatively affect system performance.

8.1 Specific Connections

Wiring Connections

Refer to the drawings in this manual and any other drawings provided by Liebert for this installation. Make all of the following connections:

1. AC power cables from input power source circuit breaker (RIB) to each UPS Module Input. Observe phase rotation.

2. AC power cables from bypass power source circuit breaker (BIB) to UPS system bypass input at System Control Cabinet (SCC). Observe phase rotation.

CAUTION

If there are line-to-neutral loads connected to the UPS output, the bypass input source must be wye connected and have three phases plus neutral plus ground. If the specified input is not available, an isolation transformer is required. Refer to 6.1 - Preferred Grounding

Configuration, Wye-Connected Service, 6.3 - Preferred Grounding Configuration With Isolated Bypass and 6.4 - Alternate Grounding Configuration, Non-Isolated.

See 6.0 - Configuring Your Neutral and Ground Connections for an explanation of proper grounding techniques.

3. AC power cables from each UPS module output to SCC or to switchgear for critical load bus. Observe phase rotation.

4. Each UPS module must have its output neutral connected to the SCC for parallel operation. A minimum of a parity-sized neutral wire is recommended on this circuit for optimum system performance, regardless of the load configuration.

5. AC power cables from UPS System Control Cabinet (SCC) Output to critical load or maintenance bypass panelboard or switchgear. Observe phase rotation.

NOTE

If your installation includes a Maintenance Bypass Panelboard or switchgear, some or all power cables will be terminated in that equipment. Make sure all required wiring between the UPS system and this switchgear is completed per the submittal drawings. Observe phase rotation.

6. The UPS System Control Cabinet (SCC) neutral must be connected to one common point and solidly grounded per requirements of the National Electrical Code. The ground connection inside the UPS SCC/switchgear cabinet may be required by the power wiring configuration at your site.

CAUTION

UPS bypass and system output neutral must be connected to only one common point in the UPS system. This neutral line must be grounded at the source. Refer to 6.0 - Configuring Your Neutral and Ground Connections for further details.

7. For battery systems: DC power cables (and ground) from battery to UPS module and between battery cabinets/strings. Observe polarity. When multiple conduits are used, an equal number of positive and negative cables should be contained in each conduit.

NOTE

DC power and battery circuit breaker control cables are provided with Liebert battery cabinets for use between multiple cabinets when bolted together. Power cables are sized for interconnecting battery cabinets. Battery cabinets specified for bolting up to the UPS are shipped with power cables to connect the battery cabinet system to the UPS module. Fieldsupplied cabling must be provided to connect stand-alone battery cabinets to the UPS module. Connections from the final battery cabinet to the UPS are provided in the field.

WARNING

Do not make any connections between battery tiers in the battery cabinet. These connections will be made by the Liebert Global Services representative during start-up.

8. For remote battery: Install DC power cables (and ground) from battery to Module Battery Disconnect, and then to UPS Module DC bus. Observe polarity.

CAUTION

9. Module Battery Disconnect control wiring to UPS module and between battery cabinets, if applicable. Wiring must be run in individual separate steel conduit.

10. Control wiring from System Control Cabinet (SCC) to UPS modules. Wiring must be run in individual separate steel conduit. Refer to Figures 30, 31 and 38 through 42 or your submittal drawings.

11. Control connections between the System Control Cabinet (SCC) and the Maintenance Bypass panelboard or switchgear. Refer to your submittal drawings.

Notes for Tables 6 and 7

1. Nominal rectifier AC input current (considered continuous) is based on full rated output load. Maximum current includes nominal input current and maximum battery recharge current (considered noncontinuous). Continuous and noncontinuous current limits are defined in NEC 100. Maximum input current is controlled by current limit setting, which is adjustable. Values shown for maximum settings are 125% of nominal input current. 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 current for 10 minutes.

3. Bypass AC input current (considered continuous) is based on full rated 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 output 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 (power cable drop plus return cable drop as measured at the module) at maximum discharge current.

7. Grounding conductors to be sized per NEC 250-122. Neutral conductors to be sized for full capacity—per NEC 310-15 (b)(4)—for systems with 4-wire loads and half capacity for systems with 3-wire loads.
