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.*
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.
WARNING
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."
