  • Page 10: Chapter 1 Overview

    Chapter 1 Overview This section provides a short introduction to the Liebert EXS 10kVA - 20kVA UPS (hereafter referred to as “the UPS”), covering features, design concept, parallel system, operating mode, battery management and battery protection. 1.1 Features The UPS is connected between a critical load (e.g. a computer) and the mains power supply to provide high quality power for the loads.
  • Page 11 Input Output Maintenance bypass switch Maintenance bypass Static switch Bypass input Bypass input switch Rectifier Inverter UPS output Mains input Rectifier input switch Output switch Automatic inverter switch Battery Battery charger Figure 1-1 Block diagram illustrating the working principle of a UPS single module The UPS has its own battery charger and adopts advanced temperature compensation technology to effectively prolong the battery service life.
  • Page 12 Should this condition occur, please contact your local VERTIV customer service centre for technical support. (Parallel System) In the event of a fault on a UPS module, it will automatically exit the parallel system. If the system is still capable of providing the power required by the load, the remaining modules will continue to supply the load without interruptions.

  • Page 13: Parallel System

    Maintenance bypass The UPS is equipped with a second bypass circuit, known as the maintenance bypass, which provides a safe working environment for the engineers to carry out regular maintenance or repair the UPS system, while providing unregulated mains supply to the loads. The maintenance bypass can be activated manually selected by closing the maintenance bypass switch, and disconnected by setting the switch to OFF.

  • Page 14: Operating Modes

    Parallel System Features 1. The hardware and software of a parallel system are identical to those of the individual modules. The parallel system is configured by modifying the respective settings in the configuration software or via the control panel. 2. Parallel cables are connected in a ring, providing both system reliability and redundancy. LBS cables are connected between any two UPS modules of each bus.
  • Page 15 Battery mode As shown in Figure 1-4, the operating mode where the battery provides the backup power supply to the loads through the rectifier and inverter is called battery mode. In the event of a mains failure, the system will transfer automatically to battery mode with no interruption in the power supply to the load.

  • Page 16: Battery Management

    Never use batteries having different brands, type or capacities in the same system. Common battery string mode is suitable for parallel systems only, and is not compatible with LBS mode. 1.5 Battery Management The following battery management functions are set by the service engineer using the VERTIV setting software. Normal Function 1. Constant current boost charge Uses a constant current (within battery charging limit) to charge the battery.

  • Page 17: Battery Protection

    9. Maximum boost charge protection time To protect against the battery overcharge damage caused by long time boost charge, it is essential to set-up a protection time a protect time limit This limit value is set-up by the service engineer using the VERTIV setting software.

Insert the relay card into the UPS. Note The relay card is hot-pluggable, therefore it may be installed without shutting the UPS down. a) Remove the Intellislot port cover (see Figure 3-6) on the front panel.
  • Page 95 (common input configuration), bypass input (split-bypass configuration), and output terminals together. Note The UPS is set to 3-in 3-out mode by default. If you need to convert it to 3-in 1-out mode, contact VERTIV authorized personnel for the corresponding settings. Always observe the following procedures: Power distribution mode 1.
