8. Operation

CAUTION

Operators should be qualified* personnel.

Operation of the UPS by unqualified or untrained personnel may result in electric shock, injury or failure.

* In accordance with customer stipulations

Make sure you understand the meaning of the warning labels on the equipment, and follow the precautions indicated.

Operating the equipment with an inadequate understanding of these matters may result in electric shock or burns.

See Page 6 for the location of these warning labels.

This section will describe the basic procedures used to operate the UPS.

NOTES

Operate the unit within the ambient conditions noted in the specifications.

Operating the unit outside these ranges may result in failure.

During operation, do not turn off the air conditioner for the UPS chamber and the battery chamber.

This will cause the temperature in these chambers to rise and may result in failure.

When starting or stopping the equipment, monitor the operation on the graphic display panel LCD and follow the procedures.

Do not leave the unit for long periods of time (1 week) with control power source switch (8A) in the OFF position.

This can cause the backup capacitor on the control board to become discharged and result in incorrect time display and other problems.

8.3.6 Changing to Floating Charge etc. (for MSE individual battery)

Table 8.7 shows the procedure used to change manually from protective charge to floating charge.

This operation does not apply to shared battery systems.

(1) An MSE battery normally operate in floating charge mode.

(2) To prevent the battery temperature from rising, the mode changes automatically to protective charge mode when a "BATT FAULT1" (BATTERY OVER TEMP.) warning occurs.

(3) In protective charge mode, the battery is automatically charged at a voltage about 5% lower than normal (floating) charge when the battery temperature has risen above the rated value, in order to prevent deterioration caused by excessive charging at high temperatures.

(4) After a set amount of time has elapsed (about 6 hours), if the "BATT FAULT1"

(BATTERY OVER TEMP.) warning message has disappeared, the mode will automatically change back to floating charge. As a result, it will not normally be necessary to change the mode manually as described below.

9.2.4 Scrolling Through LCD Screens in the Event of Failure

NOTES

When the unit has stopped due to failure, be sure to remove the memory card before resetting the LCD Failure Error screen on the panel, so you can give it to the service person.

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.

Touching the other sections of the unit may result in electric shock.

This section describes how to scroll through the LCD screens when a failure has occurred (in other words, when Failure Data screens exist).

Figure 9.8 shows the locations of the scroll keys used to scroll through the LCD screens. See

Table 9.9 and Figure 9.9 for a discussion of the scroll keys and how they are used for screen scrolling.

Note that pressing the "RESET" key k will delete the waveform data stored on the memory card as well as the Failure and Warning Data Screens. Be sure to remove the memory card before pressing the "RESET" key.

9.4 Restoring UPS Operation

WARNING

Contact the Toshiba Service Center in the event of malfunction or failure.

This unit should be repaired only by authorized Toshiba service personnel. Servicing by untrained personnel may increase the scale of the failure or result in electric shock or injury.

Do not attempt to modify or move the unit yourself or to have this done by a third party.

Electric shock, injury or failure may result if persons other than specially trained Toshiba technicians attempt to modify or move the unit. Be sure to contact Toshiba if you wish modifications to be made or if you wish to move the unit.

Only open the front panel when performing necessary operations.*

Operating parts and high-voltage areas inside the UPS have been provided with covers as a safety precaution. Still, touching areas other than those that must be touched to perform necessary operations may result in electric shock, burns or other injuries.

* In this case, "necessary operations" means operating circuit breakers/auxiliary switches and inserting/removing memory cards.

Do not open the rear door.

The parts inside carry high voltage. Touching them may result in electric shock, burns or failure.

This section describes the procedure used to restore UPS operation. Table 9.11 shows an example in which the UPS is restored after a trip error has occurred on circuit breaker 52R with the message "52R TRIP."
