Battery Installation

3.3.2Connecting the Batteries

If the Liebert NX battery cabinets are installed on a raised floor, the battery power cables and circuit breaker control cables may be routed to the UPS cabinet via the floor of the cabinet (bottom entry).

If the Liebert NX battery cabinets are installed adjacent to one another on a solid floor, these cables may be passed between the cabinets through lifting slots in the lower sides of the cabinets.

Intertray connections must be made before the battery cabinet can be used.

3.3.3Installation Considerations

Position— If the system includes a matching maintenance bypass cabinet (MBC), the MBC should be installed first and the battery cabinet installed on the opposite side of the UPS. Otherwise, left- side placement of the battery cabinet is preferable.

The battery cabinet(s) are designed to be located conveniently next to each UPS module, and are also available in stand-alone configurations with painted side panels. The front access design eliminates side and rear service clearance requirements. Refer to Table 28 for battery cabinet dimensions and weights.

Bolt-OnCabinets—Matching battery cabinets are designed to bolt onto the side of the UPS module cabinet. Use bolts that ship with each unit to connect cabinet frames at posts, two places in the front and two places in the rear.

Service Clearance—Allow front access to the battery cabinet at all times for maintenance and ser- vicing. Electrical codes require that the battery cabinet be installed with no less than 3 feet (1m) of clearance at the front of the cabinet when operating. Side and rear panels do not require service clear- ance.

Cables—Cables may be run between the cabinets through cutouts in the top of the cabinet, eliminat- ing the need for external conduit runs. Route cables before moving cabinets into final position for bolt- ing together. No top or bottom entry cables are required, except for remotely located cabinets which require conduits.

Software—To allow the UPS to accurately display the battery run time, the number of battery cabi- nets must be noted when performing initial startup and setup using the configuration software. This is to be performed by the Liebert Global Services customer engineer when commissioning the unit.

Casters and Adjustable Stops—The adjustable stops are not designed to bear the full weight of the cabinet. Lower the stops until they are finger-tight in contact with the floor. Then tighten a small amount with a wrench (less than two turns) to give a good friction fit. When mounting the battery cabinet on seismic stands, ensure that the casters are bearing the weight of the cabinet.

Battery Support Tray—Be sure to connect the battery tray support to the front of the cabinet before sliding a battery tray out for connection or service. Without the support, the battery tray may fall out of the cabinet. See Figure 13 for details.

480V specifications

The Emerson 480V power systems play a critical role in modern industrial applications, providing reliable and efficient power distribution. These systems are designed for facilities that require robust performance and operational efficiency while adhering to safety regulations. With voltage ratings at 480V, they cater primarily to industries such as manufacturing, data centers, and commercial buildings.

One of the main features of the Emerson 480V systems is their scalability. These systems can be easily adapted and expanded as operational demands grow, thereby reducing initial investment costs and providing a flexible solution for evolving business needs. This ability to scale is crucial in a fast-paced environment where demands can change rapidly.

The Emerson 480V systems also incorporate advanced technologies for improved performance and safety. One key technology is the use of smart grid solutions. This enables real-time monitoring, diagnostics, and control, allowing facility managers to optimize energy consumption and reduce operational costs. Furthermore, these systems often include integrated protection devices that enhance safety measures by minimizing the risk of electrical faults, overloads, or short circuits.

Energy efficiency is another characteristic that distinguishes Emerson 480V systems from traditional alternatives. With advanced power management features, these systems effectively reduce energy waste and lower electricity bills. Emerson’s commitment to sustainability is evident in its designs, which aim to minimize environmental impact through energy-efficient technologies.

The build quality of Emerson 480V systems is also noteworthy. They are designed to withstand harsh industrial environments and are constructed with high-grade materials that promote longevity and reliability. The modular design allows for easy maintenance and repair, which further extends the lifespan of the system.

Additionally, Emerson 480V systems are equipped with user-friendly interfaces that facilitate ease of operation. This ensures that operators can efficiently manage and control power distribution without extensive training. The combination of performance, scalability, safety features, and user-centric design makes Emerson 480V systems an ideal choice for businesses looking to enhance their electrical infrastructure.

In summary, Emerson 480V power systems are a leading solution for industrial power distribution, characterized by their scalability, smart technology integration, energy efficiency, robust build quality, and user-friendly operation. These attributes make them a valuable investment for any organization aiming to improve its electrical management and operational performance.
