Do not apply electrical power to the UPS equipment before the arrival of the commissioning engineer. 1.2 Preliminary Checks Before installing the Liebert eXM MBC, carry out the following preliminary checks: • Visually examine the equipment for transit damage, both internally and externally. Report any damage to the shipper immediately. • Verify that the correct equipment is being installed. The equipment supplied has an identification tag on the back of the main door reporting: the type, size and main calibration parameters of the UPS. • Verify that the room satisfies the environmental conditions stipulated in the equipment specifications, paying particular attention to the ambient temperature and air exchange system. 3 Liebert® eXM™ MBC™ Mechanical Installation 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, cleanair 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 Table 10). 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 Table 12 for the weight of the Liebert eXM MBC 200mm and 300mm models. Tables 11 through 13 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. Handling the unit with straps is not authorized. ! WARNING Risk of moving heavy units and tipping hazard.

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 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 Table 20). Ensure correct phase rotation! 6. Connect the system output power cables between the Liebert eXM MBC output (A-B-C terminals) and the critical load and tighten the connections to the proper torque (see Table 20). 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 Table 20). 8. Replace the panels.

The manual is available at the Liebert Web site: www.liebert.com The following are guidelines only and are superseded by local regulations and codes of practice where applicable. • 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. 9 Liebert® eXM™ MBC™ Installation Drawings 2.0 INSTALLATION DRAWINGS Figure 2 One-line diagram, dual-input, two-breaker Liebert 480V MBC, 50-250kVA system MAINTENANCE BYPASS CABINET MBB *Bypass AC Input 3 Wire + GND See Note 5 MIB *UPS AC Input 3 Wire + GND Output Busbar AC Output 480V 3 Wire + GND Static Bypass UPS CABINET BATTERY NOTES: 1.
