Page 3: System Overview
1. SYSTEM OVERVIEW 1.1. CONSTRUCTION OF THE UNIT WARNING! Be sure to operate the converter within its rated capacity. Prevent direct exposure to sunlight, rain, or any other contaminating environment. The System is composed of an input breaker, input filter & protection network, rectifier, inverter, isolation transformer and output filter. - Page 4 e. High frequency design: The inverter uses high frequency, high efficiency IGBTs, and PWM to convert the DC power to AC power. The number of components is reduced, resulting in increased reliability, smaller size and weight, less transportation cost, improved performance, and the elimination of acoustic noise.

1.3. FRONT PANEL The front panel gathers the real time information of the UNIT and displays the data clearly. It also provides switches for controlling and setting the UNIT. Each part of the panel is explained below: A. LCD display- Real time status, data, and historical events are displayed on the LCD. The UNIT parameters, real time clock, inverter, buzzer also can be set through this LCD. - Page 6 D. Buzzer outlet: The buzzer is located inside the UNIT. When abnormal conditions occur, a clearly audible sound will be issued to warn the user to check the UNIT. The buzzer will beep under any the following conditions: 1. INVERTER IS OVERLOADED >...

2. INSTALLATION 2.1. SITE & ENVIRONMENT CONSIDERATIONS The primary function of the UNIT is to provide a safe, clean independent electrical supply to the load which is : A) Perfectly regulated in both voltage and frequency B) Free from any random variations, disturbances or interruptions. The following precautions and recommendations should be checked in considering the site and environment of the UNIT: a. - Page 8 The walls, ceiling, floor, or anything near the UNIT should be constructed of non-combustible materials. A portable fire extinguisher should be accessible. k. Avoid accumulating litter or trash of any sort in or around the UNIT. The floor area surrounding the UNIT should be kept clean so that metallic filings and powder are not sucked into the unit causing a short circuit and possible damage to the system.

Page 11: Operations
OPERATIONS After all cables have been connected, the converter is ready to operate once the power source is available at the input terminal. Before you turn on any switch or breaker, check the following points listed below: a. See if the input voltage is within tolerance for the converter’s rated input voltage. b. -
Page 12: Shutdown Procedure
3.2. SHUTDOWN PROCEDURE If you want to shutdown the converter completely (no power at the output or inside), please follow the steps below. a. Open the Output breaker. WARNING – If there is no load or the load has been disconnected externally prior to opening the Output breaker, the output terminals will maintain a DC voltage due to filter capacitors on the output terminals. -
Page 13: Lcd Display
4. LCD DISPLAY The LCD screen can display much more information than LED’s. In order to make the display sharp and readable, the LCD is back-lit. To prolong the life time of the back-lighting, the CPU will turn off the back light after 3 minutes if no keys are pressed. -

4.11. MENU 10 – HISTORICAL DATA <DATE/TIME/EVENTS> RUN:00YR00MO 2003/09/10 14:14 FUSE/OVERHEAT This menu is selected from MENU 1, the SELECT MENU. The records are stored in EEPROM when abnormal events occur and are displayed in this menu. The record display begins with the date and time stamp of each abnormal event. The user or maintenance personnel can trace back these events up to 77 records (which can be increased to 154 records with 2 EEPROMs). -
Page 19: Redundancy ( System Back - Up )
5. REDUNDANCY ( SYSTEM BACK – UP ) Redundancy can be roughly divided in two types: serial (hot standby) redundancy and parallel (active) redundancy. A serially redundant system consists of two converters, with the output of the second converter connected to the reserve input of the first converter. -
