Operation

Second Scenario

Power is supplied to the UPS and the UPS is supplying the load. (Upstream breakers are closed). The UPS should be showing either the SYSTEM RATINGS screen or the Mimic display. If the SYS- TEM RATINGS screen is showing, use the arrow keys to select SAVE & EXIT and push SELECT. This will advance you to the USER SETTINGS screen. The USER SETTINGS have been pre-set at the factory. However, they may be customized for your site. See 3.3.5 - Configuration Screens for detail information on configuration screens. You can change these configurations at any time. Use the arrow keys to move the cursor to SAVE & EXIT and push SELECT. This will move you to the MIMIC screen. Check the MIMIC screen to make sure the static switch contactors are closed. The screen should look like Figure 22. If the Static Switch Contactors are open (Figure 24), transferring to the NORMAL position will DISCONNECT THE LOAD. To close the Static Switch contactors, locate the Rotary Switch located on the inside of the cabinet on the lower right side as you face the cabinet. Turn the Rotary Switch to the SERVICE position. Wait for 10 seconds. Return the Rotary Switch to the BYPASS position. This should reset the Static Switch contactors to the closed position and the MIMIC panel should look like Figure 22. If the Static Switch contactors are closed, then the load is supported by Static Switch and you are clear to move the Rotary Switch to the NORMAL position and move on to Auto Startup on page 28. If the Static Switch contactors are not closed, repeat the above procedure. If this still does not close the static switch, contact Liebert Global Services for assistance.

! CAUTION

If on Static Bypass, make sure the Static Switch is closed (Figure 22) before turning the Rotary Switch to normal. If the Static Switch is not closed and the Rotary Switch is turned to the normal position, the load will be disconnected.

STARTUP / SHUTDOWN

MANUAL STARTUP

USER SHUTDOWN

EXIT

Auto Startup

Normally, the Operator will choose to start the system automatically for the sake of convenience. To begin the auto start-up sequence, select MAIN MENU from the MIMIC screen. This will bring up the MAIN MENU Screen (Figure 9). From this screen select STARTUP/SHUTDOWN. This will take you to the STARTUP/SHUTDOWN screen, Figure 23. Move the cursor to AUTO STARTUP and press SELECT. AUTO STARTUP mode starts the rectifier and inverter, and transfers the load to the inverter. The operator needs only perform one action when prompted: CLOSE MANUAL BATTERY BREAKER. This action must be performed promptly (within 90 seconds). Otherwise the startup oper- ation is aborted and an error message will appear stating: UPS OPERATION CANNOT BE PER- FORMED. Although no further operator interaction is required, the Operator has the option to abort the Auto sequence.

Once the Operator has manually closed the Battery Breaker, the UPS automatically becomes fully operational, at which point the Mimic Display Screen is displayed showing Normal Power Flow. See Figure 10.
