Resistance between housing and protective earth
N
connection.
The low resistance pass is to be controlled according to
N
VDE 0701/0702 (sports and fitness machines) or VDE
0751/IEC 60601-1 (medical devices) by the protective
resistance measurement with a measuring device for the
protective earth resistance measurement.
The connecting lead is to be moved while measuring for
N
at least 5 sec. If the resistance thus changes, it is highly
probable that the cable or the connectors have been
damaged. In this case the cable should be replaced and
the device repaired immediately.
Resistance between „bridged" L+N and Protective Earth-
N
Connection.
Make sure that all isolations that are under stress of the
N
mains voltage, are considered. All switches and
contactors should be connected.
The measurement is to be performed with measuring
N
devices for the isolation resistance measurement
according to VDE 0701/0702 (sports and fitness
machines) or VDE 0751/IEC 60601-1 (medical devices).
Impedance measurement, indicating the current in the
N
protective earth cable
The measurement is to be performed by a measuring
N
device for leakage current measuring according to VDE
0701/0702 (sports and fitness machines) or VDE
0751/IEC 60601-1 (medical devices).
The measurement is equivalent to the single fault earth
N
leakage current based on IEC 60601.
