Unpacking and Preliminary Inspection, Storage

2.0UNPACKING AND INSTALLATION

2.1Unpacking and Preliminary Inspection

1.Inspect the shipping crate(s) for damage or signs of mishandling before unpacking the unit.

2.Remove any securing bands and cardboard packing and inspect the unit for any obvious shipping damages.

3.If any damage as a result of shipping is observed, immediately file a claim with the shipping agency and forward a copy to your local Liebert sales representative.

2.2Handling Considerations

Larger units are bolted to a shipping pallet to facilitate handling by forklift or pallet jack. Check the size and weight. Refer to the cabinet data furnished with the unit. Typical size and weights are referred to in Table 1.

2.3Storage

The unit should be stored in a clean, dry environment. Storage temperature range is -55ºC to +85ºC (-67ºF to +185ºF). Care should be taken to avoid condensation. All packing and shipping materials should be left intact until the unit is ready for final installation. If the unit has been stored for an extended period of time, the unit should be cleaned and carefully inspected before placing into service.

2.4Location Considerations

Environment—The unit is designed for operation indoors in ambient temperatures of -40°C to +60ºC (-40ºF to +140ºF) with a relative humidity of 0% to 95% (non-condensing).

The unit is provided in an industrial use enclosure that is dust-tight and drip-tight. The unit should not be installed in areas with excessive dust, corrosive vapors, flammable materials or explosive atmospheres.

Audible Noise—The audible noise of the unit is less than 40 dBA at five feet, which allows its placement in almost any room.

Service Clearances—Service clearance is needed only at the front of the unit. Thirty-six inches (36 in or 914 mm) minimum is recommended.

2.4.1Equipment Performance

For maximum system performance, the unit must be located as close to the protected circuit as practical to minimize interconnecting wiring length.

For optimum transient surge protection, coordinated surge suppression should be applied at the service entrance and all other electrical connections to the building (telephone, CATV, etc.), at known surge generating loads within the building (large motors, arc welders, switched capacitors, etc.), as well as at sensitive electronic loads (such as computers, electronic appliances, solid state motor drives, etc.). For interconnected electronic loads (such as by way of data cabling), transient surge suppression should also be applied to the interconnecting wiring (data cables).

Mounting—Unit is intended to be wall-mounted. Refer to Figure 1 or unit submittal drawings for typical mounting dimensions and weight.

2.5Door Closing Adjustments

If the surface on which the enclosure is mounted is not flat, the door may not open and close prop- erly. Also, if heavy equipment is mounted on a large door, the door may sag slightly. If the top of the door strikes the lip that extends around the body opening, place metal shims behind the mounting foot that is located at the bottom of the enclosure and closest to the door hinge. Place the shims between the mounting foot and the wall or mounting surface. Be sure all mounting screws are tightened securely

II specifications

Liebert II is a high-performance precision cooling system designed specifically for mission-critical applications, ensuring that data center facilities maintain optimal temperatures for sensitive equipment. As part of Emerson's extensive line of cooling solutions, the Liebert II is particularly valued for its reliability, efficiency, and adaptability.

One of the standout features of the Liebert II is its sophisticated cooling technology, which incorporates both chilled water and air-cooled systems. This dual capability allows it to operate effectively in a variety of environments, whether in a small server room or a large data center. The unit is engineered to deliver consistent cooling across different loads, catering to fluctuating demands characteristic of modern IT environments.

In terms of performance, the Liebert II boasts variable speed fans that adjust to the cooling requirements in real-time, thus maximizing energy efficiency. This feature not only reduces operational costs but also minimizes the carbon footprint of the facility. Furthermore, the system is designed with advanced electronic controls that offer precise temperature management, allowing for rapid response to any changes in operating conditions.

The Liebert II also includes state-of-the-art monitoring and control features. It supports integration with advanced Building Management Systems (BMS), providing operators with the tools to oversee performance metrics, detect potential issues before they escalate, and implement energy-saving strategies. This level of operational visibility is crucial for maintaining uptime in critical environments.

Another significant characteristic of the Liebert II is its modular design, which simplifies maintenance and scalability. Facilities can easily upgrade or expand the system as needs evolve, ensuring that the cooling solution can keep pace with technological advancements and increased loads. The design also promotes ease of access for service technicians, minimizing downtime during maintenance activities.

Finally, noise reduction is an important aspect of the Liebert II’s design. The system operates quietly, making it suitable for environments where noise levels must be kept at a minimum, such as offices adjacent to IT spaces.

In summary, the Liebert II stands out as a top choice for ensuring reliable precision cooling in data centers, thanks to its advanced technology, energy efficiency, modular design, and operational flexibility. These attributes position it as an essential component in the infrastructure of any modern facility relying on high-performance computing.
