[. . . ] Shared battery system: A parallel UPS system in which there is a single battery for all UPS units in the system. HS: Vent type stand-alone lead storage battery AHH: Sintered electrode type alkaline storage battery MSE: Sealed stand-alone lead storage battery Individual battery system: (4) Display Graphic display panel: LCD: LED: Scroll buttons: Includes push buttons, display lamps, and the LCD panel used to display UPS operating procedures and the UPS state. This shows the operational procedure and the status of the UPS unit. Individual lamps located on the graphic display panel indicate the status of the UPS unit. [. . . ] The operator can switch between these screens by pressing the scroll keys. : Scroll up : Scroll down Normal Display screen Failure Data Display screen Warning Data Display screen - 20 - 6F3H1001 7. 2. 1 Normal Display Screen The Normal Display screen indicates the operational status of the UPS and provides a total of nine screens: one Operation Guidance Display screen and eight Measurement Value Display screens. Table 7. 2 presents examples of these screens. Table 7. 2 No. 1 LCD Screen Help screen (Example 1) Operation status OPERATION GUIDANCE MOVE #52R TO "ON" POSITION Normal Display Screen Description Shows the status of the UPS at the top and help messages or measurements underneath. (Example 1)Shows help messages when starting or stopping operation. (Example 2) UPS SUPPLY (Example 2)Shows the output voltage and output current during operation. 200[V] 50[%] Voltage (example) Current ratio (example) AC-VO AC- I O 2 Measurement screen (Example) Output voltage O/P VOLTAGE (LINE) Shows the output voltage between lines. U- V V-W W- U 3 200[V] 200[V] 200[V] Shows the RMS value for the output current for each phase as a proportion (%) of the rated value.

For the current value, "-" indicates charging and the absence of a plus/minus sign indicates discharging. 9 Measurement screen (Example) Counter value MODE COUNT UPS 17544[H] BATTERY 32[MIN] 0[TIM] Shows the total time of UPS operation and the number of times the battery has been operated and total time for battery use (the time AC input has been off). - 22 - 6F3H1001 7. 2. 2 Failure Display Screen The Failure Display screen indicates the presence or absence of failure data and displays that data if present. Table 7. 3 LCD Screen Presence or absence of failure data FAULT NO FAULT INFORMATION Failure Display Screen Description This screen indicates the presence or absence of failure data. This screen is displayed if there is no failure data, or if all failure data has been reset with the "fault display rest" key. Failure data FAULT 1 52R TRIP 98-09-09 08:05:30 ANOTHER ITEM The failure data, the time the failure occurred, and an indication as to whether or not there is any other failure data is displayed with this screen if a failure occurs. Turns off the control power supply and shuts down the UPS completely. Changes the mode for battery charging (in the case of HS or AHH individual battery). Used to change the charging mode manually from protective charge to floating charge (in the case of an MSE individual battery). Changes the supply of power to the load to bypass power supply (when the UPS must be shut down completely for maintenance, inspection, etc. ). 7 Supply power to maintenance bypass Page 39 8. 2 Pre-operational check Be sure to check the following items before operating the UPS: (1) Make sure all internal covers are in place. If doors are opened to operate circuit breakers, switches and the like, be sure to close them afterward. (3) Make sure the air conditioners in the UPS chamber and battery chamber are operating. (4) When starting up the UPS, make sure all circuit breakers (52R, 72B, 52C, 52L and 52M) and switches (8A and 6CH) are off. (Certain systems are also provided with the switch 8D. ) (5) When starting up the UPS, check on the equipment supplying power to the UPS to make sure AC input voltage is being supplied to the UPS. - 26 - 6F3H1001 8. 3 Procedures 8. 3. 1 Startup Table 8. 1 shows the procedure used to start up the UPS.

Resetting (restarting) the UPS without removing the memory card will delete the data needed to determine the cause of the failure. Every effort has been made to ensure safety in unit handling. However, when removing the memory card, do not touch the other sections of the unit. [. . . ]
