12 DEFINITIONS UNINTERRUPTIBLE POWER SUPPLY SYSTEM (UPS) - All componen wihin he UPS Module Cabine and aociaed baerie ha funcion a a yem o provide coninuou, condiioned AC power o a load. Thi i omeime referred o a he "Syem". UPS MODULE CABINET - The meal encloure which conain he Converer / Charger, Inverer, Saic Tranfer Swich, Inernal Bypa line, operaor conrol, and inernal conrol yem required o provide pecified AC power o a load. UPS MODULE - The Converer / Charger and Inverer aemblie which, under he direcion of he inernal conrol yem and operaor conrol, provide pecified AC power o a load. INVERTER - The UPS componen which conain he equipmen and conrol neceary o conver DC power from he Converer / Charger, or he baery, o AC power required by he criical load. CONVERTER / CHARGER - The UPS componen which conain he equipmen and conrol neceary o conver inpu AC power o regulaed DC power required for baery charging and for upplying power o he Inverer. STATIC TRANSFER SWITCH - The device which connec he criical load o he bypa line when he Inverer canno upply coninuou power. BYPASS LINE - The line which conduc elecriciy direcly from he inpu power ource o he criical load during Mainenance or whenever he UPS i no compleely operaional. AC INPUT POWER - Power provided by he elecrical uiliy company, or auxiliary generaor, which i conneced o he UPS for upplying he criical load.

13 OPERATION OVERVIEW The UPS provide wo power pah beween he uiliy ource and he criical load. Figure 1.1 how he pah for normal operaion, wih he load powered from he inverer. Figure 1.2 how he pah for bypa operaion, wih he load upplied hrough he aic bypa line. A) Normal operaion: Load power upplied by each yem UPS inverer. Figure 1.1 Single Line Diagram - Normal Operaion: Load powered by UPS inverer Bypa inpu CB UPS Module 52S Uer upplied Saic Tranfer Swich CB3 CB CB1 CONVERTER / CHARGER INVERTER 52C AC inpu Oupu Uer upplied Power Flow No in Ue Baery Cabine CB2 Exernal BATTERY During normal operaion, he pah hrough he UPS inverer i ued o power he load. Referring o Figure 1.1: Inpu AC power i convered o DC by he Converer. DC power i uilized o charge he UPS baery and o provide power o he Inverer. The Inverer conver he DC power o clean AC power o upply he criical load. The converion - inverion proce eliminae any volage ranien or flucuaion exiing in he inpu power before i reache he criical load. The power drawn by he criical load i equally hared beween all UPS whenever he yem i in he Parallel Operaion. (Refer o Figure 3.4 ha how a ample of Parallel Operaion Syem Configuraion.) MITSUBISHI

14 1-8 In he even of a UPS module failure during Parallel Operaion, he criical load power will be coninually upplied and hared by all oher UPS. The Bypa Inpu circui breaker (MCCB) for proecion of he UPS and cable are field upplied and field inalled. (See WARNING 4 on page 1-4) B) Bypa Operaion: Load Power upplied hrough UPS inernal aic bypa line. FIGURE 1.2 Single Line Diagram - Bypa Operaion: Load fed hrough aic bypa line. Bypa inpu CB UPS Module 52S Uer upplied Saic Tranfer Swich CB3 CB CB1 CONVERTER / CHARGER INVERTER 52C AC inpu Oupu Uer upplied Power Flow No in Ue Baery Cabine CB2 Exernal BATTERY Referring o Figure 1.2: The Inernal Bypa line i a Hard-wired line hrough 52S which upplie he criical load wih uncondiioned bypa inpu power. Upon wiching o he Inernal Bypa line, he Saic Tranfer Swich line hrough CB3 (herein afer STS conacor CB3) upplie he power immediaely, and hen he Inernal Bypa line hrough 52S upplie he power. In he even of a wiching o he Bypa line, he power o he criical load will be uninerruped. The purpoe of hi Inernal Bypa line i o roue power o he criical load while he UPS module i de-energized (converer and inverer), and during Sar-up before he yem i fully operaional. Each UPS inernal aic bypa line will equally hare he power upplied o he criical load whenever he yem i in he Parallel Operaion. MITSUBISHI

15 1-9 In he even of a load overcurren, he UPS ranfer o bypa wihou inerrupion o he criical load. In he cae of he Parallel Operaion, all UPS will ranfer o bypa wihou inerrupion o he criical load. The inernal conrol yem deermine he operaion of he wo pah, wih he load powered from he inverer being he normal operaion. C) Baery operaion: Load Power upplied by UPS baery. FIGURE 1.3 Single Line Diagram - Baery Operaion Bypa inpu CB UPS Module 52S Uer upplied Saic Tranfer Swich CB3 CB CB1 CONVERTER / CHARGER INVERTER 52C AC inpu Oupu Uer upplied Power Flow No in Ue Baery Cabine CB2 Exernal BATTERY Referring o Figure 1.3: In he even of AC inpu ource failure or inerrupion, he UPS Converer()* will de-energize and he UPS baery()* will immediaely dicharge and upply DC power o he Inverer o mainain coninuou AC power o he load. Thi operaion will coninue unil: a) The baery capaciy expire and he inverer urn off, or b) Inpu power i reored afer which he converer will power he inverer and criical load and imulaneouly recharge he baerie. A fully charged baery will provide power for he pecified ime a he raed load, or longer, a a reduced load. ()* : In he cae of he Parallel Operaion MITSUBISHI

16 1-10 When power i reored afer a low baery hudown, he UPS converer()* auomaically rear operaion, he charger()* recharge he baerie and he Inverer()* i auomaically reared wihou operaor inervenion. Load i auomaically aumed by he inverer wihou operaor inervenion. ()* : In he cae of he Parallel Operaion The power drawn by he load i equally hared beween all UPS regardle of he preence or abence of he UPS ha i (are) in baery operaion or no whenever he yem i in he Parallel Operaion..
