IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS

This manual contains important instructions that should be followed during installation of your Liebert NX™ UPS and ancillary equipment.

Read this manual thoroughly, paying special attention to the sections that apply to your installation, before working with the UPS. Retain this manual for use by installing personnel.

! WARNING

Exercise extreme care when handling UPS cabinets to avoid equipment damage or injury to personnel. The UPS module weight ranges from 1180 to 1290 lb. (535 to 585kg).

Determine unit weight and locate center of gravity symbols before handling the UPS. Test lift and balance the cabinet

before transporting. Never tilt equipment more than 15 degrees from vertical.

Battery manufacturers supply details of the necessary precautions to be observed when working on, or in the vicinity of, a large bank of battery cells. These precautions should be followed implicitly at all times.

Follow all battery safety precautions when installing, charging or servicing batteries. In addition to the hazard of electric shock, gas produced by batteries can be explosive and sulfuric acid can cause severe burns. When connected, the nominal battery voltage is 480VDC and is potentially lethal.

In case of fire involving electrical equipment, use only carbon dioxide fire extinguishers or those approved for use in fighting electrical fires.

Extreme caution is required when performing maintenance. Be constantly aware that the UPS system contains high DC as well as AC voltages.

Check for voltage with both AC and DC voltmeters prior to making contact.

! WARNING

As with other types of high power equipment, dangerous voltages are present within the UPS and battery enclosure. The risk of contact with these voltages is minimized as the live component parts are housed behind a hinged, lockable door. Further internal safety screens make the equipment protected to IP20 standards.

No risk exists to any personnel when operating the equipment in the normal manner, following the recommended operating procedures.

All equipment maintenance and servicing procedures involve internal access and should be carried out only by trained personnel.

! WARNING

High ground leakage current: Ground connection is essential before connecting the input supply.

This equipment must be grounded in accordance with local electrical codes. Maximum load must not exceed that shown on the UPS rating label.

! CAUTION

This equipment is fitted with RFI suppression filters.

Ground leakage current exceeds 3.5 mA and is less than 30 mA.

Transient and steady-state ground leakage currents, which may occur when starting the equipment, should be taken into account when selecting instantaneous residual current circuit breakers (RCCBs) or residual current devices (RCDs).

RCCBs must be selected sensitive to DC unidirectional pulses (Class A) and insensitive to transient current pulses.

Note also that the ground leakage currents of the load will be carried by this RCCB or RCD.

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.
