D)MMS Start-up Procedure

a)Verify that Critical Load Cabinet (CLC) Circuit Breaker SMB is closed.

b)Verify that CLC System Output Circuit Breaker 52L is open

c)Verify that CLC UPS Circuit Breakers 52L1, 52L2…and 52Ln are closed.

Start-up of UPS-1

1.Verify that Control Circuit Breakers (CPM) is closed.

(When Inverter is stopped, the Control Circuit Breaker is not normally opened)

2.The pre-charging cycle will begin and Input Contactor (CB1) will close automatically.

3.Close Battery Disconnect Circuit Breaker (CB2).

4.The inverter can now be started.

Note: When "REMOTE OPERATION MODE" is displayed on the LCD panel, the inverter start operation can only be performed remotely. If local inverter start operation is required (at the UPS), select "LOCAL" in "Remote/Local" selection in setup page. Select “LOCAL” mode for the purpose of this start up procedure.

5.On the LCD panel, select “START/STOP MENU” and press the “START” key.

6.The Inverter will start within 5 seconds. Start up is complete.

Start-up of next UPS

1.The next UPS can be started in the same way as UPS-1.

2.When all UPS in MMS are started, the MMS system UPSs will simultaneously transfer from UPS MMS Bypass Operation to UPS MMS inverter Operation.

3.Verify there are no alarms on each UPS LCD and CLC LCD (if available)

Any steps to verify correct UPS MMS Inverter Operation.

Transfer from UPS MMS Inverter Operation To UPS MMS Bypass Operation

1.Transfer MMS system to UPS MMS Bypass Operation on CLC LCD (if available) or Transfer each UPS to bypass individually

Transfer of Load From Maintenance Bypass To inverter

1.Verify UPS MMS system is in UPS MMS Bypass Operation.

2.Transfer load from CLC Maintenance Bypass Circuit Breaker (SMB) to system Output Circuit Breaker (52L) per MMS CLC Maintenance Mode Interlock Operating Procedure, Part B.

3.Transfer from UPS MMS Bypass Operation to UPS MMS Inverter Operation from CLC LCD “System Bypass Operation Screens” if available or by starting each Individual UPS from UPS LCD, select “START/STOP MENU” and press “START” key.

4.After all UPS are ready to transfer to inverter all UPSs will simultaneously transfer from internal bypass to inverter.
