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)
- The device fuse inserted at the rear end of
complies with the data given in the
(check imprinting on the fuse).
Patient Support System
- All Warning Labels as defined in the
are complete, legible and
Guide, Patient Support System
show no damage.
- The housing, including the bellows is not

damaged or loose. All parts are securely fastened.
- The covers and mechanical parts of the ON/OFF-
switches are not damaged, loose or otherwise impaired
by wear.
- The covers and mechanical parts of the Lock-All push
buttons are not damaged, loose or otherwise impaired
by wear.
- The cover of the Battery Charger 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
figures 1/2/3 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 Battery Charger and switch
Verify that the resistance of the protective earth connection
between upper and lower metal housing plate of
complies with the requirements of IEC62353 (see figure 4 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
verify the Equipment Leakage Current from accessible
conductive parts complies with the requirements of IEC62353
(see figure 5 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 Battery
Charger. Therefore disconnect the Battery Charger from

Verify the insulation resistance between the primary and
secondary circuits of the Battery Charger 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' push buttons 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
Patient Support System
Release.
The function works as described. After the test

switches:
The device can be turned 'ON' and 'OFF' by operating
the switches on either side. Both switches are lit to
indicate the 'ON'-state of
- Inspect and test the correct function of the Lock-All
push buttons:
The device can be 'Locked' and 'Unlocked' by
operating the push buttons on either side. Both buttons
are lit to indicate the 'Locked'-state of
- Test the Emergency OFF (EMO):

7. Reporting of results (6.1 – IEC62353)
All tests performed as stated above shall be documented
comprehensively.
