Battery Installation

3.0BATTERY INSTALLATION

3.1Introduction

If using multiple sets of batteries connected in parallel to provide the required battery backup run times, fit each set with an isolating device to permit working on one of the battery sets while leaving the others in service and providing backup protection.

When replacing batteries, replace with the same manufacturer and type, or equivalent. See your Lie- bert representative for a list of approved batteries.

3.2Safety

Special care should be taken when working with the batteries associated with the Liebert NX system equipment. When all batteries are connected together, the battery terminal voltage may exceed 480V and is POTENTIALLY LETHAL.

! WARNING

The Liebert NX's internal batteries are connected and energized even if the UPS is turned Off. To minimize the risk of injury, a qualified service person should disconnect the batteries before any maintenance is performed on the unit.

A battery can present a risk of electrical shock and high short circuit current. The following precautions should be observed when working on batteries:

• Remove watches, rings and other metal objects.

• Use tools with insulated handles.

• Wear rubber gloves and boots.

• Do not lay tools or metal parts on top of batteries.

• Disconnect charging source prior to connecting or disconnecting battery terminals.

! CAUTION

To reduce the risk of fire, connect only to a circuit provided with DC amperes (see Table 12) maximum branch circuit overcurrent protection in accordance with the National Electric Code, ANSI/NFPA 70.

NOTE

The maximum available fault current from the battery supply is 8500A and the DC voltage rating of the battery supply overcurrent protective device that is to be installed near the battery supply must be at least 600VDC.

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.
