IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS

This manual contains important safety instructions that should be followed during the installation and maintenance of the UPS and batteries. Please read this manual thoroughly before attempting to install or operate this UPS.

! WARNING

SAFETY PRECAUTIONS

To prevent the risk of fire or electric shock, install the UPS in a temperature and humidity controlled room, free of conductive contaminants, moisture, flammable liquids, gases and corrosive substances.

Operate the UPS only from a properly grounded (earthed) 220-240 VAC, 50Hz or 60Hz AC supply.

To reduce the risk of electric shock, do not remove the cover—it has no user-serviceable parts inside except the internal battery pack. Some components are live, even when AC power is disconnected. For internal battery pack servicing, follow the instructions provided in 10.3 - Battery Replacement. For other service, contact a qualified technician.

! WARNING

ELECTRICAL PRECAUTIONS

• This UPS should not be supplied from electrical power systems of the IT (Impedance á Terre) type (IEC 364 - Electrical Installation of Buildings).

• The UPS must be earthed/grounded at all times during operation. Connect only to a mains supply socket outlet with an earth/ground connection.

! CAUTION

Although your UPS has been designed and manufactured to ensure personal safety, improper use can result in electrical shock or fire. To ensure safety, please observe the following rules:

• Turn Off and unplug your UPS before cleaning. Do not use liquid or aerosol cleaners. A dry cloth is recommended to remove dust from the surface of your UPS.

• Do not install or operate your UPS in or near water.

• Do not place UPS on an unstable cart, stand or table.

• Do not place UPS under direct sunlight or close to heat emitting sources.

• Never block or insert any objects into the ventilation holes or other openings of the UPS. Keep all vents free of dust accumulation that could restrict air flow.

• Do not place UPS power cord in any area where it may get damaged by heavy objects.

! WARNING

If your UPS demonstrates any of the following conditions, turn Off and unplug your UPS from the outlet and contact your local dealer, Liebert representative or Liebert Worldwide Support Group:

•The power cord or plug is damaged.

•Liquid has been spilled on the UPS.

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.
