8. Operation
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
CAUTION
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.
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.
NOTES
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.

Be sure to check the following items before operating the UPS:
(1) Make sure all internal covers are in place.
(2) Make sure all doors are closed. If doors are opened to operate circuit breakers, switches
and the like, be sure to close them afterward.
(3) Make sure the air conditioners in the UPS chamber and battery chamber are operating.
(4) When starting up the UPS, make sure all circuit breakers (52R,72B,52C,52L and 52M)
and switches (8A and 6CH) are off. (Certain systems are also provided with the switch
8D.)
(5) When starting up the UPS, check on the equipment supplying power to the UPS to make
sure AC input voltage is being supplied to the UPS.

In equalized charge mode, the battery is charged for a set period of time at a voltage about
5% (depending on the type of battery) higher than normal (floating) charge, in order to
prevent variations in battery performance. This must be done about once every six months, in
spring and autumn if possible.
The TOSNIC-7000S UPS is equipped with a function that performs the equalized charging
process automatically when restoring the battery charge after a power outage or the like.

(2) Table 8.5 shows the procedure used to change manually from equalized charge to
floating charge.
After the charging mode has been changed to equalized charge using the procedure
on the previous page, the mode will automatically change back to floating charge after

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
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.
NOTES
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
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.*
WARNING
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."
