5.4External Battery Cabinet Installation

Optional Liebert external battery cabinets may be connected to the UPS to provide additional battery run time. External battery cabinets are designed to be placed all on one side of the UPS or stacked beneath the UPS. The run time is limited to a maximum of four (4) hours.

! CAUTION

The external battery cabinet(s) are heavy (see 12.0 - Specifications). External battery cabinets can be used in rack-mount or tower configuration. Take proper precautions when lifting them.

1.Visually inspect the external battery cabinet for freight damage. Report damage to the carrier and your local dealer or Liebert representative.

2.The rack-mount handles are shipped with the external battery cabinet and may be installed at this time (see 5.3 - Rack-Mount UPS Conversion and Installation).

3.Fixed rails and securing hardware ship with the external battery cabinet. Fasten the fixed rails into position with the screws per the instructions included with the UPS. Repeat

Steps 1 through 10 from 5.3 - Rack-Mount UPS Conversion and Installation.

4.Use the support bases included with the UPS for the tower option to prevent tip-over. One additional set of support base spacers ships with each external battery cabinet.

5.Connect the supplied external battery cabinet cable to the rear of the external battery cabinet, then to the rear of the UPS, as shown at right.

6.The UPS is now equipped with additional backup battery run time. For approximate battery run times, refer to Table 5 - Battery run times.

PSITM specifications

The Liebert PSITM is an advanced power protection system designed to ensure the reliability and efficiency of critical systems in data centers, industrial applications, and mission-critical environments. As the demand for uninterrupted power supply continues to grow, the Liebert PSI serves as an indispensable asset.

One of the main features of the Liebert PSI is its online double-conversion technology. This method guarantees a continuous supply of clean and stable power to connected loads by converting incoming AC power to DC, then back to AC. This process eliminates power disturbances such as voltage sags, surges, and harmonics, ensuring that sensitive equipment operates without interruption.

In addition to its robust power protection capabilities, the Liebert PSI offers scalable solutions to meet varying power requirements. Ranging from 5 kVA to 40 kVA, it can be configured for single or three-phase operation. This flexibility allows businesses to tailor the system to match their specific needs, whether they are expanding data center operations or simply upgrading existing infrastructure.

Another notable characteristic of the Liebert PSI is its energy efficiency. The unit is designed to operate with a high efficiency of up to 94%, which not only reduces operational costs but also minimizes the environmental impact. Moreover, it features an eco-mode that optimizes energy use during non-critical operations without sacrificing reliability.

The Liebert PSI is equipped with advanced communication and management capabilities. It includes an intuitive LCD display for real-time monitoring, enabling users to access vital information about the unit's performance and status. Additionally, it supports various communication protocols such as SNMP and Modbus, allowing for seamless integration into existing management systems.

Furthermore, the Liebert PSI is designed with an emphasis on modularity, allowing for easy upgrades and maintenance. This modular approach reduces downtime and enhances serviceability, ensuring that the system remains reliable throughout its lifecycle.

In summary, the Liebert PSITM stands out as a comprehensive power protection solution that combines cutting-edge technology, energy efficiency, and user-friendly features. Its commitment to safeguarding critical systems against power disturbances makes it a vital component in the infrastructure of any modern data center or industrial setting.
