10-6-1 Safety Test Overview
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 VIVID E9.
Prior to initiating any electrical test, the VIVID E9 must be visually inspected. Perform the following
visual checks:
• Check for missing or loose enclosure covers that could allow access to internal live parts.
• Examine the mains cord, mains plug and appliance inlet for damaged insulation and adequacy of
strain relief and cable clamps.
• Locate and examine all associated transducers. Inspect the cables and strain relief at each end.
Inspect the transducer enclosure and lens for cracks, holes and similar defects.
Equipment users must ensure that safety inspections are performed whenever damage is
suspected and at least every 12 months in accordance with local authorities and facility
procedures. Do not use the VIVID E9 or individual probes which fail any portion of the safety
test.
WARNING WARNING
ENERGY CONTROL AND POWER LOCKOUT FOR VIVID E9.
WHEN SERVICING PARTS OF THE 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 VIVID E9.
4. MAINTAIN CONTROL OF THE POWER PLUG.
5. WAIT FOR AT LEAST 20 SECONDS FOR CAPACITORS TO DISCHARGE, AS THERE ARE NO TEST POINTS TO
VERIFY ISOLATION. THE AMBER LIGHT ON THE OP PANEL ON/OFF BUTTON WILL TURN OFF.
BEWARE THAT THE MAIN POWER SUPPLY AND BACK END PROCESSOR MAY BE ENERGIZED EVEN IF THE POWER
IS TURNED OFF WHEN THE CORD IS STILL PLUGGED INTO THE AC OUTLET.
WARNING WARNING
TO MINIMIZE RISK OF ELECTRIC SHOCK, ONLY TRAINED PERSONS ARE ALLOWED
TO PERFORM THE ELECTRICAL SAFETY INSPECTIONS AND TESTS.
CAUTION
To avoid electrical shock, the unit under test MUST NOT be connected to other electrical
equipment. Remove all interconnecting cables and wires. The unit under test must not be
contacted by users or patients while performing these tests.
CAUTION
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.
