Installation

4.Attach the two (2) fixed rails to the racks mounting rails. The fixed rail assemblies fit on the inside of the rack mounting rails.

5.Insert two (2) M5 flat head screws loosely (finger-tight) into the top and bottom holes on the front of the fixed rail assembly (see Figure 9).

6.Extend fixed rail by sliding inner member backward until it touches the rear rack mounting rail.

7.Insert two (2) M5 screws loosely (finger-tight) into top and bottom holes on the rear of the fixed rail assembly.

8.Check alignment of fixed rails and tighten all screws to ensure locking action.

9.Lay the UPS in rack-mounting position on the fixed rails. The UPS should move smoothly forward and backward on the fixed rails. If not, recheck alignment.

! CAUTION

Lifting equipment into rack may be a two-person job, depending on weight of equipment.

10.Use the extra M5 screws provided, secure front of the UPS to rack mounting rails to prevent the UPS from sliding out of position.

11.PowerSure PSI 230 VAC models are not supplied with an input power lead for connection to the mains supply. Additional input/output cords may be obtained from your dealer. The input power cord must have a minimal cross-sectional area of 1mm2.

12.Shut down the load equipment and turn off the mains supply. Unplug the load equipment's power input cable from the mains supply socket and plug it into the UPS input socket.

Plug the power input cable into the mains supply socket. Connect the supplied IEC-320-C14 output power cable between the load equipment input socket and one of the UPS AC output sockets.

13.Connect all load equipment to the UPS in this manner.

14. Turn On the UPS by pressing the ON button. Check that the AC Input Indicator is not flashing. If it is flashing, refer to 11.0 - Troubleshooting. Then turn

On the connected equipment. The UPS is now providing conditioned power to your equipment.

! CAUTION

To maintain safety (SELV) barriers and electromagnetic compatibility, signal cables should be segregated and run separately from power cables.

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.
