Operator’s Manual C - 1
C 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 which comply with IEC 60601-1 and are used in Europe, such as
Fluke, Metron or Gerb, may require modifications to the procedure. Follow the analyzer
manufacturer's instructions.
An electrical safety inspection should be periodically performed every two years. The safety
analyzer is also an excellent troubleshooting tool for detecting abnormalities in line voltage and
grounding, as well as total current loads.
Make sure the safety analyzer is authorized and complies with the requirements of IEC 61010-1.
Follow the analyzer manufacturer's instructions.
