contents of this file to glean more in-depth information about the cause of inexplicable faults
or other problems such as blown fuses or defective thyristors.
When contacting Siemens with queries related to problems of this type, it is, therefore,
advisable that you both read out this file and e-mail a copy of it to the Siemens experts.
