Maintenance

10.0MAINTENANCE

The PowerSure PSI UPS requires very little maintenance. Follow these practices to prevent prob- lems.

10.1Cleaning the UPS

The following will help ensure trouble-free operation for years:

•Vacuum dust from the ventilation intake occasionally.

•Wipe the cover periodically with a dry cloth.

10.2Maintaining Batteries

The batteries are valve-regulated, nonspillable, lead acid and must be kept charged to retain their design life. The UPS continuously charges the batteries when connected to the mains supply, even while the UPS is switched Off.

When storing the UPS, it is recommended to plug in the UPS for at least 24 hours every four to six months to ensure full recharge of the batteries.

The PowerSure PSI is designed to allow the user to replace the internal batteries safely. Read the safety cautions before proceeding. Contact your local dealer or Liebert representative to obtain the appropriate replacement battery kit part number and pricing.

10.3Battery Replacement

! CAUTION

A battery can present a risk of electrical shock and high short circuit current. The following precautions should be observed before replacing the batteries:

•Remove rings, watches, and other metal objects.

•Use a Phillips (crosshead) screwdriver with insulated grips.

•Do not lay tools or other metal objects on top of the batteries.

•If the battery replacement kit is damaged in any way or shows signs of leakage, contact your local dealer or Liebert representative immediately.

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

•Dispose of old batteries according to local codes.

•Risk of explosion if battery is replaced by an incorrect type. Refer to 12.0 - Specifications for battery information.

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

NOTE

This UPS is equipped with internal “hot swappable” batteries that the user can replace without shutting down the UPS or connected loads. Caution should be exercised when replacing the batteries because the load is unprotected from disturbances and power outages during this procedure.

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.
