8. Operation

CAUTION

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

6 F 3 H 1 0 0 1

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.

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

Operating the unit outside these ranges may result in failure.

NOTES

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.

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.

8.3.7 Changing the Power Supply to Maintenance Bypass

This UPS must be completely shut down when performing maintenance and inspections. In
such cases, the power supply to the load will go through the maintenance bypass. Table 8.8
shows the procedure used to change the power supply to this maintenance bypass. Table 8.9
shows how to change the power supply from the maintenance bypass back to the UPS.

9. Troubleshooting

When an error occurs on the UPS, error data is displayed on the LCD screen and the
waveform is saved. This section will describe the types of errors, the error messages
displayed on the LCD screen, the process of saving waveforms and the procedures used to
correct the errors.

9.1 Types of Errors

The following types of errors may occur on the UPS:

No. Name Description

1 Fault (Trip) The UPS has been tripped and has stopped operating.

4 Warning-3

(Operation

control)

5 Warning-4

(guidance)

The converter has been stopped and power is being supplied
from the battery. When the warning has been corrected, power is
automatically supplied from AC input.

The unit changes to bypass power supply and the UPS stops
operating. When the warning has been corrected, the unit will
automatically be restarted and revert to UPS power supply.

An error or phenomenon related to an error occurred. Since this
problem does not directly affect operation, the system switches to
synchronized mode.

An error or indication of an error has occurred, but operation was
not affected.

9.4 Restoring UPS Operation

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

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

6 F 3 H 1 0 0 1

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.

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.

WARNING

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."

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 op era ting 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.
