Internal Inspections, Preliminary Checks

Installation

1.2Internal Inspections

1.Remove any packaging material, then visually examine the UPS and battery equipment for transit damage, both internally and externally. Report any such damage to the shipper and to Liebert immediately.

2.Check the nameplate inside the cabinet door to verify that the model number and rating correspond to the ones specified. Record the model number and serial number in the front of this installation manual. This information is necessary should service be required.

3.Check for loose connections or unsecured components in the cabinet.

4.Check for shipping damage to internal components.

1.2.1Storing for Delayed Installation

If the equipment will not be installed immediately, it must be stored indoors where the humidity is no higher than 90% and the temperature is no higher than 104°F (40°C). The storage area must protect the Liebert NX from excessive moisture (see 5.2 - UPS Environmental).

! CAUTION

If the battery cabinet must remain disconnected from power for more than six (6) months, the battery must be recharged before use. To charge the batteries, the battery cabinet must be connected to the Liebert NX UPS and the UPS must be connected to utility power and started up because the charger operates only while the Liebert NX UPS is operating.

! CAUTION

When batteries are installed in a cabinet adjacent to the UPS unit, the battery—not the UPS—dictates the designed maximum ambient operating temperature.

1.3Preliminary Checks

1.3.1Identification

The equipment supplied has an identification tag on the back of the main door listing the type and size of the UPS.

1.4UPS Location

1.4.1Positioning the UPS

Choose a location for the UPS that offers:

•Easy connection to inputs, outputs and auxiliary equipment

•Enough space to service the UPS

•Air circulation sufficient to expel heat produced by UPS

•Protection against moisture and excessive humidity

•Protection against dust and other particulate matter

•Compliance with fire prevention regulations and practices

•Operating environment temperature of 74-80°F (23-27°C) for maximum battery efficiency

1.4.2Environmental Considerations

Before installing the Liebert NX, verify that the UPS room satisfies the environmental conditions stipulated in 5.2 - UPS Environmental, paying particular attention to the ambient temperature and air exchange system.

The UPS unit should be installed in a cool, dry, clean-air environment with adequate ventilation to keep the ambient temperature within the specified operating range 32°F to 104°F (0°C to 40°C).

For optimal UPS and battery system performance and service life, maintain the operating tempera- ture within the range of 74-80°F, (23-27°C).

The Liebert NX UPS cooled by internal fans. Cooling air enters the unit through the front of the unit and is exhausted out the top. To permit proper air flow and prevent overheating, do NOT block or cover the ventilation openings or blow air down onto the unit. Ventilation clearance above the unit must be a minimum of 8 in. (203mm).

See Table 7 for details on heat dissipation.

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.
