Installation

1.6.1Clearances

There are no ventilation grilles on the sides or rear of the UPS. The unit may be placed with the rear against a wall and optional cabinets on either side.

To enable routine tightening of power terminations within the UPS, make sure there is sufficient clearance in front of the Liebert NX to permit free passage of personnel with the door fully opened.

Leave a minimum of 8 in. (203mm) between the top of the UPS and the ceiling to permit adequate air circulation above the unit. Liebert recommends against using air conditioning or other systems that blow air onto the top of the unit.

1.6.2Floor Installation

The diagrams in 6.0 - Installation Drawings show the location of holes in the base plate for bolting the equipment to the floor.

If the equipment is to be placed on a raised floor, it should be mounted on a pedestal that will support the equipment point loading. Refer to the bottom view in Figure 21 to design this pedestal.

1.6.3Cable Entry

Cables can enter the Liebert NX from the top or bottom. Cable entry is made possible by removing a metal plate attached to the UPS.

These plates are designed to allow the personnel to punch holes for fitting and securing the conduit. Once the conduit holes are punched, these plates should be reattached to the UPS.

! CAUTION

To reduce the risk of fire, connect only to a circuit provided with correct amperes maximum branch circuit overcurrent protection (see Table 8) in accordance with the National Electric Code, ANSI/NFPA 70.

NOTE

When installing the UPS, the customer must provide a disconnect with overcurrent protection at the output of the UPS.

System Composition

A UPS system can comprise a number of equipment cabinets, depending on the individual system design requirements—e.g., UPS cabinet with External Bypass cabinet and Maintenance Bypass cabi- net. In general, all cabinets used will be the same height and are designed to be positioned side-by- side to form an aesthetically appealing equipment suite.

1.6.4Optional Cabinets

The Maintenance Bypass Cabinet must be cabled and bolted to the Liebert NX before the UPS and bypass cabinet are moved into their final position. Connect the input wiring to the Maintenance Bypass Cabinet ONLY after the units are connected and positioned.

Battery cabinets may be bolted to either side of the Liebert NX; see Figure 1.

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.
