Safety Technical Inspection
ENGLISH
1. General
The device shall be maintained and serviced on a regular basis,
at least once a year, based on the requirements of IEC62353 -
Medical electrical equipment - Recurrent test and test after
repair of medical electrical equipment .
For details about performance of the inspection as well as the
assessment of the results of the tests strictly follow the
requirements of IEC62353.
The following sections refer to referenced chapters in the
above mentioned standard and serve to support the inspection
accordingly.
Use only certified testing equipment intended and designed to
perform tests according IEC62353.
2. Visual inspection (5.2 – IEC62353)
- All Warning Labels as defined in the
are complete, legible and show no

damage.
- The housing, including the bellows is not

damaged or loose. All parts are securely fastened.
- The cover of the Auxiliary Power Supply does not show
any cracks or other damage.
- No twists or cracks in cable jacket and no damage to
connectors

functional earth conductor (FE) connecting the upper
and lower metal housing plate and verify the
connection is not impaired by wear or fatigue (see
figures1/2/3 for details):
- There are no obvious cracks in the isolation or sharp
bending of the conductor
- The mechanical connection of the conductor to upper
lower housing plate is not loose
AND
3. Measuring of protective earth (PE) resistance (5.3.2 –
IEC62353)
Disconnect the Auxiliary Power Supply.
Verify that the resistance of the protective earth connection
between upper and lower metal housing plate of
complies with the requirements of IEC62353 (see figure4 for
details).
- The measured internal PE-resistance shall not exceed
0.2 Ω.
4. Leakage currents (5.3.3 – IEC62353)
Perform an Equipment Leakage Current test with
and verify the Equipment Leakage Current from accessible
conductive parts complies with the requirements of IEC62353
(see figure5 for details).
- The Equipment Leakage Current shall not exceed the
limits as specified in IEC62353
- Allowed limits differ depending on the type of
measurement setup. For details please refer to
IEC62353
5. Measurement of insulation resistance (5.3.4 – IEC62353)
The insulation resistance shall only be measured at the
Auxiliary Power Supply. Therefore disconnect the Auxiliary
Power Supply from .
Robotics OEM
Verify the insulation resistance between the primary and
secondary circuits of the Auxiliary Power Supply in accordance
with the requirements of IEC62353 (see figure 6 for details).
- The insulation resistance shall meet as a minimum the
limits as specified in IEC62353

6. Functional test (5.4 – IEC62353)
The safety related functions of the equipment shall be tested
as follows:
- Test the Service Lock mechanism:
Both arresting bolts can be operated easily to both the
'Locked' and the 'Unlocked' position.
The indicator lights in the 'Lock All' are lit on both sides
of Robotics if an arresting bolt is not in its normal
'Unlocked' position.
- Test the Service Brake Release:
Follow the instructions in the

The function works as described. After the test
Robotics indicates the occurrence of a Service Brake
Release and a 'Homing' procedure is required.
- Test the Emergency OFF (EMO):
