Appendix B Electrical Safety
Inspection
The following electrical safety tests are recommended as part of a comprehensive preventive
maintenance program. They are a proven means of detecting abnormalities that, if undetected,
could prove dangerous to either the patient or the operator. Additional tests may be required
according to local regulations.
All tests can be performed using commercially available safety analyzer test
equipment. These procedures assume the use of a 601PRO
XL
International Safety
Analyzer or equivalent safety analyzer. Other popular testers complying with IEC
60601-1 used in Europe such as Fluke, Metron, or Gerb may require modifications to
the procedure. Follow the instructions of the analyzer manufacturer.
The consistent use of a safety analyzer as a routine step in closing a repair or upgrade
is emphasized as a mandatory step if an approved agency status is to be maintained.
The safety analyzer also proves to be an excellent troubleshooting tool to detect
abnormalities of line voltage and grounding, as well as total current loads.
