Start the Liebert XDP with Liebert iCOM

5.0START THE LIEBERT XDP WITH LIEBERT ICOM

5.1Checklist for Liebert XDP Startup

! CAUTION

Risk of piping and component rupture. May cause equipment damage or injury.

Closing service valves may isolate liquid refrigerant, causing high pressure and rupture of piping. Do not close valves without following recommended procedures for repair, maintenance and replacement of components. Install pressure relief valves in field piping that may become isolated by service valves.

NOTE

The Liebert XDP160 requires a minimum load of 48kW (163,800BTU/H) before the system can be commissioned. This load can be supplied by actual user load in racks, by independent load banks or by the “Load Bank Testing” service of Emerson Network Power Liebert Services. To achieve the minimum load requirements, the capacity of all connected modules must total at least 48kW (163,800BTU/H). See Table 1.

NOTE

Before any action that could cause a disturbance in the Liebert XD system’s cooling function is begun, the facility manager MUST be informed. In addition, after the action is taken and the work is finished, the facility manager MUST be informed

1.Verify that bypass flow controllers were installed (if applicable), see Table 5.

2.Verify that the minimum load level of 48kW (163,800BTU/H) is present.

3.Check all isolation ball valves in the Liebert XDP and Liebert XD cooling module and verify that all are open.

4.Check rotation of the Liebert XDP’s pumps.

On 460V units only—Hold the rotation device provided against the pump housing at the inspection screw prior to energizing the pumps. Counterclockwise indicates proper rotation; clockwise indicates incorrect rotation.

On 208V and 400V units only, view the LED indicator on the pump. Green indicates proper rotation; Green and Red indicate incorrect rotation.

6.Verify that air is being discharged into the cold aisle.

7.Confirm that the total calculated refrigerant R-134a amount has been properly charged into the system (see 3.6 - Filling the Pumped Circuit—R-134a).

8.Confirm that the remote temperature/humidity sensors provided have been installed in optimal locations (see 2.4 - Remote Sensor Installation—Proper Placement)

The Liebert XDP system is now ready to be turned ON.

XDP160RA, XDP160RC, XDP160RM specifications

The Liebert XDP series is an innovative line of uninterruptible power supplies (UPS) designed to safeguard critical IT equipment and ensure reliability in demanding environments. The XDP160RM, XDP160RC, and XDP160RA models are distinguished by their robust features and advanced technologies, making them ideal for data centers, server rooms, and telecommunications.

One of the standout features of the Liebert XDP series is its high power density. The XDP160RM, XDP160RC, and XDP160RA models provide 160 kVA of power in a compact design, occupying minimal floor space. This efficient design maximizes data center performance without compromising on reliability.

All three models utilize advanced digital signal processing (DSP) technology that enhances system performance and efficiency. The DSP technology ensures high efficiency rates, often exceeding 95% in online mode. This not only reduces energy costs but also minimizes heat output, contributing to a more sustainable operational environment.

The Liebert XDP series is equipped with multiple output configurations, allowing for versatile installation options. The modular architecture of the UPS systems allows for easy scalability to meet future power demands without the need for complete system replacement. This flexibility is crucial for businesses expecting growth or changes in IT infrastructure.

Another important aspect of the XDP160RM, XDP160RC, and XDP160RA is their advanced battery management systems, which optimize battery performance and longevity. The integrated smart battery charging technology prevents overcharging and extends battery life, ensuring that the UPS is always ready during power interruptions.

Additionally, the systems are designed with user-friendly interfaces that facilitate ease of monitoring and management. With real-time data on power usage, battery status, and overall system health, IT administrators can quickly address any issues that arise. The monitoring capabilities extend to remote access, enabling users to manage the UPS systems from virtually anywhere.

The Liebert XDP series also incorporates enhanced safety features, including fault detection and automated alerts, which further bolster reliability. With a strong commitment to maintaining uptime and safeguarding critical operations, the XDP models are a wise investment for any organization reliant on continuous power availability.

In conclusion, the Liebert XDP160RM, XDP160RC, and XDP160RA UPS systems are engineered to deliver exceptional power protection through high efficiency, advanced technologies, and user-friendly management features. These models are positioned to meet the rigorous demands of modern IT environments, ensuring that businesses can maintain operations without interruption.
