10-7-2 Safety Test Overview
NOTE: 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.
The electrical safety tests in this section are based on NFPA 99 Standard 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 planned maintenance (PM) 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 and UL 60601-1) which require a controlled test
environment and can place unnecessary stress on the Ultrasound system.
DANGER TO AVOID ELECTRICAL SHOCK, THE ULTRASOUND SYSTEM UNDER TEST MUST NOT
BE CONNECTED TO OTHER ELECTRICAL EQUIPMENT. REMOVE ALL
INTERCONNECTING CABLES AND WIRES. THE ULTRASOUND SYSTEM UNDER TEST
MUST NOT BE CONTACTED BY USERS OR PATIENTS WHILE PERFORMING THESE
TESTS.
To minimize risk of electric shock, only trained persons are allowed to perform the electrical
safety inspections and tests.
Energy Control and Power Lockout for Venue Go™.
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.
Ultrasound System components may be energized.
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.
