Installation

5.0INSTALLATION

5.1Preparation

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

! CAUTION

The UPS is heavy (see Table 4 - Battery cabinet specifications). Take proper precautions when lifting or moving it.

2.Decide where to place the PowerSure PSI. Install the UPS indoors in a controlled environment where it cannot be accidentally turned Off. Place it in an area of unrestricted airflow around the unit, away from water, flammable liquids, gases, corrosives, and conductive contaminants. Maintain a minimum clearance of 100mm (4 inches) in the front and rear of the UPS. Maintain an ambient temperature range of 0°C to 40°C (32°F to 104°F).

NOTE

UPS operation in temperatures above 25°C (77°F) reduces battery life.

3.The PowerSure PSI may be installed in either a tower configuration or in a rack, depending on available space and use considerations. Determine the type of installation and follow the appropriate instructions in either Tower UPS Installation or Rack-Mount UPS Conversion and Installation.

5.2Tower UPS Installation

When using the PowerSure PSI in a tower configuration, use the included support base (shown below, left) to stabilize the UPS. If two or more battery cabinets are added, the spacers—included with the battery cabinets—should be used to accommodate the additional cabinets.

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.
