Note
Each individual device in an ME system, which has a separate connection to
the power supply mains, or which can be connected to or separated from the
power supply mains without the aid of a tool, must be checked individually.
Moreover, the ME system must be checked as one unit to avoid the situation,
in which the „aging“ of individual devices lead to unacceptable values in sum.
Note
An ME system that is connected to the power supply mains by means of a
multiple socket outlet must be treated as one device during checks and test-
ing.
Note
If the ME system or part of the system is connected to the power supply
mains by means of an isolating transformer, the transformer must be in-
cluded in the measurements.
Note
In ME systems, in which more than one ME device are interconnected via
data lines or otherwise, e. g. via electrically conductive attachments or
coolant tubes, the earth wire resistance of every single device must be
checked.
Note
If it should be impossible to check single ME devices that are functionally
connected to an ME system individually for technical reasons, the ME system
must be checked as a whole.
Components of the safety check
Visual inspection (inspection by examination)
Optical appraisal of the safe and usable condition of the medical device and its
accessories.
Measurements
▪ Measurement of the protective earth resistance in accordance with IEC
62353
▪ Measurement of the equipment leakage current - Alternative measuring
method in accordance with IEC 62353
▪ Measurement of the equivalent patient leakage current - Alternative meas-
uring method in accordance with IEC 62353
Note
A measurement of the insulation resistance in accordance with IEC 62353
need not be carried out. This check is covered by the measurement of the
leakage current provided a safety tester specified in IEC 62353 Annex C is
used!
