Vertiv™|Liebert® EXM™ MBC Installation Manual | 4

Page 11

1.3 Environmental Considerations

1.3.1 Room

The Liebert EXM MBC is intended for indoor installation and should be located in a cool, dry, clean-air environment with adequate ventilation to keep the ambient temperature within the specified operating range (see 3.0 - Specifications).

All models of the Liebert EXM MBC are convection-cooled. To permit air to enter and exit and prevent overheating or malfunctioning, do not cover the ventilation openings.

When bottom entry is used, the conduit plate can be removed and punched and replaced. The bottom conduit plate must be replaced for proper airflow. If necessary to cool the room, install a system of room extractor fans.

NOTE

The Liebert EXM MBC is suitable for mounting only on concrete and other noncombustible surfaces.

1.3.2 Storage

Should the equipment not be installed immediately, it must be stored in a room for protection against excessive humidity and or heat sources (see Tab le 1 0).

1.4 Positioning

The cabinet is structurally designed to handle lifting from the base. Access to the power terminals, auxiliary terminals blocks and power switches is from the top and

sides. The top and side removable panels are secured to the chassis by screws. The side panel can be

removed for access to the power connections bars, auxiliary terminal blocks and power isolators.

1.4.1 Moving the Cabinets

The route to be travelled between the point of arrival and the unit’s position must be planned to make sure that all passages are wide enough for the unit and that floors are capable of supporting its weight (for instance, check that doorways, lifts, ramps, etc. are adequate and that there are no impassable corners or changes in the level of corridors).

Ensure that the cabinet weight is within the designated surface weight loading (kg/cm2) of any handling equipment. See Ta bl e 12 for the weight of the Liebert EXM MBC 200mm, 300mm, 600mm, and 800mm models. Tab le s 11 through 14 provide detailed dimension and weight information for the Liebert EXM UPS and Liebert EXM MBC when they are bolted together and shipped as a system.

Ensure that any lifting equipment used in moving the cabinet has sufficient lifting capacity. The Liebert EXM MBC can be handled by means of a fork lift or similar equipment. For operations

with a fork lift, refer to installation drawings in 2.0 - Installation Drawings. Because the weight distribution in the cabinet is uneven, use extreme care during handling and

transporting. When moving the unit by forklift, care must be taken to protect the panels. Do not exceed a

15-degree tilt with the forklift.

Vertiv™|Liebert® EXM™ MBC Installation Manual | 5

Handling the unit with straps is not authorized.

WARNING

Risk of moving heavy units and tipping hazard. Can cause equipment damage, injury and death.

Exercise extreme care when handling cabinets to avoid equipment damage or injury to personnel. The Liebert EXM MBC’s weight ranges from 198 to 700 lb. (89.8 to 317.5 kg).

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.

AVERTISSEMENT

Le centre de gravité élevé des appareils présente un risque de renversement lors des déplacements pouvant entraîner des dommages matériels, des blessures et même la mort. Faites preuve d’une extrême prudence lors de la manutention des armoires afin d’éviter de les endommager ou de blesser le personnel. Les armoires de dérivation d’entretien EXM de Liebert pèsent de 198 à 700 lb (de 89.8 à 317.5 kg). Identifiez les symboles de centre de gravité et déterminez le poids de l’appareil avant de manipuler chaque armoire. Testez le levage et l’équilibre des armoires avant de transporter l’appareil. Maintenez en tout temps l’inclinaison verticale minimale.

1.4.2 Clearances

Liebert EXM MBC’s have no ventilation grilles at either side or at the rear. Clearance around the front of the equipment should be sufficient to enable free passage of personnel with the doors fully opened. It is important to leave a distance of 24" (610mm) between the top of the cabinet and any overhead obstacles to permit adequate circulation of air coming out of the unit.

1.4.3 Floor Installation/Anchoring

The installation diagrams in 2.0 - Installation Drawings of this manual identify the location of the holes in the base plate through which the equipment can be bolted to the floor. If the equipment is to be located on a raised floor it should be mounted on a pedestal suitably designed to accept the equipment point loading.

1.5 Cable Entry

Cables can enter the Liebert EXM MBC from the bottom or top.

1.6 Power Cables

The Liebert EXM MBC requires both power and control cabling once it has been mechanically installed. All control cables must be separate from the power cables. Run control cables in metal conduits or metal ducts that are electrically bonded to the cabinets they are connected to.

The cable design must comply with the voltages and currents provided in Ta bl es 1 5 through 17, follow local wiring practices and take into consideration the environmental conditions (temperature and physical support media).

AVERTISSEMENT

Risque de décharge électrique pouvant entraîner des dommages matériels, des blessures et même la mort.

Avant de procéder au câblage de l’armoire, assurez-vous que vous êtes au courant de l’emplacement et du fonctionnement des isolateurs externes qui raccordent l’alimentation d’entrée ou de dérivation.

Vérifiez que ces raccords sont isolés électriquement et installez tous les panneaux d’avertissement nécessaires pour empêcher leur utilisation accidentelle.

The following are guidelines only and are superseded by local regulations and codes of practice where applicable:

• Take special care when determining the size of the neutral cable (grounded conductor), because current circulating on the neutral cable may be greater than nominal current in the case of nonlinear loads.

• The grounding conductor should be sized according to local or NEC codes, cable lengths, type of protection, etc. The grounding cable connecting the UPS to the main ground system must follow the most direct route possible.

• Consider using smaller, paralleled cables for heavy currents as a way of easing installation.

1.6.1 Power Cable Connection Procedure

The system input, UPS bypass, UPS output and system output cables (all require lug type terminations) are connected to power blocks behind the power isolator switches as shown in

2.0 - Installation Drawings. These are accessible when the side or top panel is removed.

Equipment Ground

The equipment ground busbar is near the input and output power supply connections as shown in 2.0 - Installation Drawings. The grounding conductor must be connected to the ground busbar.

All cabinets and cable trunking should be grounded in accordance with local regulations.

WARNING

Risk of electric shock. Can cause equipment damage, injury and death. Failure to follow adequate grounding procedures can result in electric shock hazard to

personnel and the risk of fire, should a ground fault occur.

AVERTISSEMENT

Risque de décharge électrique pouvant entraîner des dommages matériels, des blessures et même la mort.

Le non-respect des procédures de mise à la terre peut entraîner des risques d’électrocution du personnel, ou des risques d’incendie en cas de défectuosité de la mise à la terre.

Vertiv™|Liebert® EXM™ MBC Installation Manual | 9

Page 16

Once the equipment has been finally positioned and secured, connect the power cables as described in the following procedure.

Refer to the appropriate cable connection drawing in 2.0 - Installation Drawings.

1. Verify that the bypass equipment is isolated from its external power source and all the power isolators are

open. Check that these supplies are electrically isolated and post any necessary warning signs to prevent their inadvertent operation.

2. Remove the panels.

3. Connect the ground and any necessary main bonding jumper to the equipment ground busbar.

NOTE

The grounding and neutral bonding arrangement must be in accordance with local and national codes of practice.

NOTE

Care must be taken when routing power cables. Ensure that the cables do not touch other busbars.

4. Connect the AC input supply cables between the power distribution panel and the Maintenance Bypass

input supply busbars (A-B-C or A-B-C-N terminals) and tighten the connections to the proper torque (see Ta bl e 2 1). Ensure correct phase rotation!

5. Connect the UPS Input

a. For two-breaker Liebert EXM MBC’s

1. If the system is a two-input type, connect the AC input supply cables between the Liebert EXM MBC

and the UPS bypass input supply busbars (A-B-C or A-B-C-N terminals) and between the power distribution panel and the UPS rectifier input supply busbars (A-B-C or A-B-C-N terminals). Tighten the connections to the proper torque. Ensure correct phase rotation!

2. If the system is a single-input type, connect the AC input supply cables between the Liebert EXM MBC

and the UPS bypass input supply busbars (A-B-C or A-B-C-N terminals) and connect AC jumper connectors between UPS bypass input supply busbars and UPS rectifier input supply busbars (A-B-C terminals). Tighten the connections to the proper torque (see Tab le 2 1). Ensure correct phase rotation!

6. Connect the system output power cables between the Liebert EXM MBC output (A-B-C or A-B-C-N

terminals) and the critical load and tighten the connections to the proper torque (see Tab le 2 1). Ensure correct phase rotation!

7. Connect the control wiring from the Liebert EXM MBC terminal block TB1 to the Liebert EXM UPS Bypass

Module (X9 J23 and J26). Tighten the connections to the proper torque (see Ta bl e 2 1).

8. Replace the panels.

The following are guidelines only and are superseded by local regulations and codes of practice where applicable.

• Take special care when determining the size of the neutral cable, because current circulating on the neutral cable may be greater than nominal current in the case of non-linear loads.

• The ground conductor should be sized according to local or NEC codes, cable lengths, type of protection, etc. The ground cable connecting the UPS to the main ground system must follow the most direct route possible.

• Consideration should be given to the use of smaller, paralleled cables for heavy currents, as a way to ease installation.

• In most installations, the load equipment is connected to a distribution network of individually protected busbars fed by the Liebert EXM MBC output rather than being connected directly to the Liebert EXM MBC itself. Where this is the case, the Liebert EXM MBC output cables can be rated to suit the individual distribution network demands rather than being fully load-rated.

• When laying the power cables, do not form coils to avoid increasing formation of electromagnetic interference.
