Electrical Safety Inspection D-1
Appendix E 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 601PROXL 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 electrical safety inspection should be periodically performed every two years.
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.
