OVERVIEW OF MANUAL The Npower manual is organized so that information can be found quickly. Each major topic is sepa- rated by sections, and there is a Table of Contents for each section. The names of the sections and their contents are described below. Section 1 - INTRODUCTION is a summary of the Npower Uninterruptible Power System (UPS). It describes some of the unique features and benefits of the Npower UPS, as well as the design princi- ples and standards that Liebert follows in the manuf

Introduction 1.0 INTRODUCTION 1.1 System Description The role of the UPS system is to supply uninterruptible, clean power to the critical load. It maintains a full-voltage, low-distortion output, even if the utility source power sags or becomes distorted. If there is an outage of the source power, the UPS maintains power to the load until an alternate source of power is activated, or until the original power source is restored. If input AC power is not restored, the UPS maintains the load (wi

Introduction 1.1.1 Reliability Reliability is the most important design goal for Uninterruptible Power Systems. All Liebert 3-Phase UPS systems have demonstrated reliability by achieving a field-proven critical bus MTBF in excess of one million hours. In addition, our Quality Assurance program is certified to the requirements of ISO 9001 standards. Liebert UPS systems are ETL listed to the requirements of UL 1778, CSA Certified and (when appli- cable) CE marked. All equipment and components

Introduction ONLY qualified service personnel should perform maintenance on the UPS system. When performing maintenance with any part of the equipment under power, service personnel and test equipment should be standing on rubber mats. The service personnel should wear insulating shoes for isolation from direct contact with the floor (earth ground). Unless all power is removed from the equipment, one person should never work alone. A second per- son should be standing by to assist and summon

Introduction 1.3.4 Overload Overloads in critical systems may be caused by inrush currents during connected equipment startup or by faults in the critical load or distribution network. The Liebert Npower UPS system can maintain full output voltage regulation while sustaining the following overloads: • Up to 125% for 10 minutes • Up to 150% for 1 minute • Up to 200% for 10 cycles For momentary faults above 200% of rated current, the static switch turns on for 10 cycles to supply power from the

Introduction 1.4 Operator Controls Liebert Npower UPS modules are equipped with a microprocessor-based Operator Display Screen and Control Panel designed for convenient and reliable operation. The front panel location of the monitor- ing and control system enables the Operator to quickly identify the current status of the UPS and to perform most of the manual operations. The operator display screen is driven by an easy-to-follow menu-prompted software program that con- trols and monitors the

Theory of Operation 2.0 THEORY OF OPERATION 2.1 General Component Description The UPS system includes all of the equipment necessary to continuously provide computer- grade AC power to a critical load, even when there is an interruption of the utility line power. It consists of the UPS modules and a back-up battery plant. Refer to Figure 2. 2.1.1 UPS Module The UPS module consists of system controls, a rectifier/charger, an inverter, protective devices, and other accessories. System Controls:

Theory of Operation 2.2 Detailed Component Descriptions 2.2.1 Controls Hardware The Npower UPS operator interface display system is designed to provide all of the information that is required for the operation of each UPS module. The following is a list of the hardware features: 1. The control logic performs automatic operations with minimal operator interface. The limited number of manual controls are easy-to-use. 2. Each Npower UPS cabinet is equipped with an easy-to-read liquid crystal disp

Theory of Operation 2.2.2 Rectifier/Charger The UPS module rectifier/charger consists of input fuses, AC current-limiting circuit, battery equalize charge circuit, DC filter, battery charge-current-limiting circuit, and bridge rectifiers. Operation The rectifier/charger converts the AC input power to DC power. This conversion is accomplished by 3- phase bridge rectifiers using SCRs. All phases are individually fused. For all modules, reflected input current THD is less than 30% at full load (w

Theory of Operation Operation After End-of-discharge The battery time screen displayed on the control panel enables you to estimate when battery shut- down will occur. You will have enough time to energize an alternate AC power source or to initiate an orderly shutdown of the critical load. If the battery plant discharges to the shutdown point during an outage, the UPS automatically disconnects the load, the AC input, and the battery. After AC input power is restored, the rectifier can be man

Theory of Operation Nonlinear Load Characteristics Computers and computer equipment with switching power supplies generate nonlinear currents rich in fifth and seventh harmonics. The inverter pulse-width-modulated waveform, coupled with the output filter, provides a natural path for reducing the fifth and seventh harmonic currents produced by the load. The inverter/filter limits the output voltage THD to less than 3% with up to 100% typical electronic data processing (EDP) loads. EDP equipme
