CONDITIONS OF USE: The mains supply socket must be within 2m (6.5 ft.) of the UPS and be eas- ily accessible.

Your UPS provides conditioned power to connected equipment. This product is designed for Commer- cial use only. It is not intended for use with life support and other designated “critical” devices. Maxi- mum load must not exceed that shown on the UPS rating label. If uncertain, consult your local dealer, Liebert representative or the Liebert Worldwide Support Group.

The PSI 1000 VA, and 1440 VA models are not supplied with an input power cable for connection to the mains supply socket. Use the input mains supply power cable from your data processing equip- ment to connect the UPS to the mains supply.

For the 2200 VA and 3000VA models, use the supplied 16A-rated input mains supply cables. For UK supply systems, consult a qualified electrician to connect the lead supplied for the 2200 VA and 3000VA models to the mains supply.

! CAUTION

The UPS and connected load total earth leakage current must not exceed 3.5mA. If the connected load earth leakage current is likely to exceed 2.5mA or you are unsure, then convert the input cable attachment to either a fixed wiring installation or an industrial plug/socket (e.g., CEE 17 connector). This alteration should be carried out by a competent electrical engineer who is conversant with local electrical codes and regulations.

When installing the UPS or making input and output connections, comply with relevant safety codes and standards (e.g. IEC60950, VDE0805, EN62040-1).

Placing magnetic storage media on top of the UPS may result in data corruption.

The equipment can be installed and operated by individuals without previous training.

! CAUTION

DO NOT CONNECT equipment that could overload the UPS or demand half-wave rectification from the UPS, for example: electric drills, vacuum cleaners, laserjet/inkjet printers, hair dryers, overhead projectors.

! CAUTION

Servicing of batteries should be performed or supervised by personnel knowledgeable of batteries and required precautions. Keep unauthorized personnel away from the batteries.

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.

•Do not dispose battery or batteries in a fire. The battery may explode.

•Do not open or mutilate the battery or batteries. Released electrolyte is harmful to skin and eyes. It is toxic.

•When replacing the battery, use same number and type of battery as the suitable recom- mended type of battery listed in Table 3.

•Handle, transport and recycle batteries in accordance with local regulations.

Electromagnetic Compatibility—The PowerSure™ PSI series complies with the requirements of the EMC Directive 89/336/EEC and the published technical standards. Continued compliance requires installation in accordance with these instructions and use of Liebert-approved accessories only.

Environmental-Operate the UPS in an indoor environment only in an ambient temperature range of 0°C to 40°C (32°F to 104°F). Install in a clean environment, free from conductive contaminants, mois- ture, flammable liquids, gases, or corrosive substances.

Provided are a Liebert MultiLink cable and a USB cable for connection to a computer. Do not use the Liebert MultiLink cable for other applications. Store in a safe place if not required at this time.

When using the communication features on this UPS, ensure the cabling connected to the DB-9 or UPS communications ports are kept separated from the power leads to the UPS input and output.

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.
