Safety Test Overview

DANGER
WARNING WARNING
CAUTION
NOTE:
The electrical safety tests in this section are based on IEC60601 standard including national deviations
for Health Care Facilities and IEC 62353 Medical electrical equipment – Recurrent test and test after
repair of medical electrical equipment. These standards provide guidance on evaluating electrical safety
of medical devices which are placed into service and are intended for use in care and maintenance or
testing following service or repair activities. They differ somewhat from the standards that are used for
design verification and manufacturing tests (e.g., IEC 60601-1 including national deviations) which
require a controlled test environment and can place unnecessary stress on the Ultrasound system.

Energy Control and Power Lockout for Venue™ .
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.
Capacitors on Ultrasound Systems with the Shearwave Option can take up to 5 minutes to
discharge.
Possible risk of infection.
Do not handle soiled or contaminated probes and other components that have been in
patient contact. Follow appropriate cleaning and disinfecting procedures before handling the
equipment.
For all instructions in the "Electrical safety tests" section, in the event of using a UPS
(uninterrupted power supply) the terms outlet, wall outlet, AC wall outlet and power outlet refer
to the AC power outlet of the UPS. In case of further available AC (or DC) power outlets at the
same used UPS, these must remain unused i.e. not connected to any other devices.
