1.2

GENERAL

The Mitsubishi 9900A SERIES UPS is designed to provide continuous and clean electrical power to a critical load. Additionally the UPS monitors power conditions affecting the load.

In the event of an input power failure, the UPS will supply power to the critical load for the

. com specified battery time.

If the input power is not restored promptly, back up power from the UPS battery permits the orderly shutdown of equipment supported by the UPS. The UPS is simple to start-up, operate and maintain.

The 9900A SERIES UPS is available in Four kVA sizes - 80, 100, 150 and 225kVA.

Specifications for each kVA model appear in Section 1.5. The principles of operation described herein are applicable to all models.

This manual provides an overview of the 9900A SERIES components and their functions.

The appearance and purpose of operator controls and indicators is described with procedures for operation, start-up, shutdown and basic maintenance included.

OPERATION OVERVIEW



The UPS provides two power paths between the utility source and the critical load.

Figure 1.1 shows the path for normal operation, with the load powered from the inverter.

Figure 1.2 shows the path for bypass operation, with the load supplied through the static bypass line.

OPERATING PROCEDURES



For Parallel Operation system, refer to section “D) MMS Start-up Procedure”.

(Parallel Operation system is herein after MMS [Multi Module System])

A) Start-up Procedure

CAUTION : Before the UPS startup, the internal Bypass line starts to supply the

unconditioned bypass input power to the critical load if the External input (or Bypass) Circuit Breaker is closed. Be extremely careful with closing the External input (or Bypass) Circuit Breaker.

. com a.) Verify that the External Bypass Input Circuit Breaker for each unit is closed.

(user supplied) b.) Verify that Battery Disconnect Circuit Breaker (CB2) is opened or in tripping position.

c.) If a dual source is feeding the UPS, close the External AC Input Circuit Breaker manually (user supplied).

d.) The LCD panel boots up automatically, and the screen will show that the Load is powered by bypass line.

e.) On the LCD panel, select “OPERATION” tab, and then press the “STARTUP

GUIDANCE” button to proceed with UPS start-up. (Refer to Figure 2.3) f.) Follow the “STARTUP GUIDANCE” accordingly until the completion of the inverter startup.

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 ONLY" or “REMOTE & LOCAL” in the OPERATION

MENU.

MITSUBISHI

ELECTRIC

B) Shut-down Procedure

If a total UPS shutdown is required, verify that the critical load is OFF.

a.) Press the "START/STOP" icon from the Main Menu or the Operation Menu on the

LCD.

b.) On the LCD panel, press “START/STOP” icon, and then select “SHUTDOWN

. com

GUIDANCE” icon. (Refer to Figure 2.3) c.) Follow the “SHUTDOWN GUIDANCE” accordingly until Inverter stops. However

UPS will simultaneously transfer the power feeding from the Inverter supply to the

Bypass line supply.

d.) In general, only the Inverter will be stopped and the Converter will remain energized to charge the batteries.

Note: When "REMOTE OPERATION MODE" is displayed on the LCD panel, the

inverter start operation can only be performed remotely. If local inverter stopt operation is required (at the UPS), select "LOCAL ONLY" or “REMOTE & LOCAL” in the

OPERATION MENU.

e.) If stopping both the Inverter and Converter is required, open the Battery Disconnect circuit breaker (CB2) manually in accordance with guidance.

WARNING : Verify the load is OFF if the next step is to be performed .

NOTE : Power to the critical load is supplied through the bypass line.

Power to the critical load will be lost after execution of the next step. The load will drop.

f.) If a dual source is feeding the UPS, open the External AC Input Circuit Breaker (user supplied) manually.

g.) If turning off all power to the critical load is desired, open the External Bypass Input www

Circuit Breaker (user supplied) manually.


Before removing the covers, wait 5 minutes after de-energizing. Check no-voltage before handling UPS. Be careful for the devices even when the UPS has been de-energized, still internal devices may be hot

.

D) MMS Start-up Procedure

External Circuit Check

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

2. Verify that CLC System Output Circuit Breaker 52L is open.

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

Start-up from UPS-1 to UPS-n

1. Start-up each UPS in accordance with “A) Start-up Procedure”. Each UPS will start

Inverter Operation in synchronization with the bypass input.

. com

Transfer from Maintenance Bypass to MMS Bypass Operation

1. Closed the CLC System Output Circuit Breaker 52L.

2. Open the CLC Circuit Breaker SMB.

(at the UPS), select "LOCAL ONLY" or “REMOTE & LOCAL” in the OPERATION

MENU.

Transfer from UPS MMS Bypass Operation To UPS MMS Inverter Operation

1. Transfer MMS Bypass Operation to MMS Inverter Operation from Operation Menu on any UPS LCD as shown in Fig. 3.6.

PARTS REPLACEMENT

Contact Mitsubishi Electric Power Products, Inc.or its authorized service representatives on all issues regarding the replacement of parts.

. com

A) Battery

Battery lifetime may vary according to the frequency of use and the average ambient operating temperature. The end of battery life is defined as the state of charge resulting in an ampere-hour capacity less than, or equal to, 80% of nominal capacity.

Replace battery if its capacity is within this percentage.

B) UPS Component Parts

UPS components have a defined life expectancy (Fan, Capacitors, Filters, etc).

Contact Mitsubishi Electric Power Products, Inc.

or its authorized service representatives for a complete parts replacement schedule.

Recommended replacement time interval varies with operating environment.

Contact Mitsubishi Electric Power Products, Inc.

or its authorized service representatives for application specific recommendations.

NOTE : Any parts replacements (including modification) without authorized by

Mitsubishi could result in personal injuries, death or destruction of the

UPS.
