10-7-2 Leakage current limits
The following limits are summarized for IEC 60601-1 Medical
Equipment Safety Standards. These limits are GEMS standards
and in some cases are lower than the above standards listed.
WARNING
Energy Control and Power Lockout for Versana Balance.
When servicing parts of the Ultrasound system where there is
exposure to voltage greater than 30 volts:
1. Follow LOCK OUT/TAG OUT procedures.
2. Turn off the breaker.
3. Unplug the Ultrasound system.
4. Maintain control of the Ultrasound system power plug.
5. Wait for at least 30 seconds for capacitors to discharge as
there are no test points to verify isolation.
6. Remove/disconnect
the battery, if present.
Ultrasound System components may be energized.
CAUTION
Compare all safety-test results with safety-test results of
previously performed safety tests (e.g. last year etc). In case of
unexplainable abrupt changes of safety-test results consult
experienced authorized service personnel or GE for further
analysis.
