Cautions on Repair

by Toshiba may not only not demonstrate the stipulated performance but also affect the safety. If
spare parts are not available, contact Toshiba to order them or ask for replacement of parts.

This equipment includes parts that need to be replaced periodically. It takes time to deliver
parts, so order them as early as possible.
1) The power modules have been designed for easy replacement as a unit. They are sold as units
and should be replaced as units. Individual parts should not be removed from or installed on the
power module assemblies. Modules that have failed or are believed to have failed should be
returned to the factory for evaluation, repair, and testing. Refer to the information label on the inside
of the power module compartment door for instructions on replacing a power module.
2) Prepare necessary tools and drawings, etc. before starting the work.
3) Be careful not to damage other parts when removing some parts.
4) Do not make wrong connections when changing parts. Put markings, etc., if necessary.
5) Before restarting after changing any part verify all connections are correct.
6) Use the right tools (torque wrench, etc.) when handling screws and bolts.
7) Special care is required when handling heavy articles.
8) When the work is completed, make sure that no tools or other foreign material is left in the drive.
