N
Impedance measurement, indicating the current in the
Protective¬Earth¬Cable
N
The measuring is to be performed by a measuring device
for leakage current measuring according to VDE
0701/0702 (sports and fitness machines) or VDE
0751/IEC 601-1 (medical devices).
N
The measurement is equivalent to the single fault earth
leakage current based on IEC 601.
N
The measuring is to be performed by a measuring device
for leakage current measuring according to VDE
0701/0702 (sports and fitness machines) or VDE
0751/IEC 601-1 (medical devices).
N
The leakage current of the equipment is to be measured
under operating conditions, if -despite closed switching-
not all isolations are seized.
N
Measurements must be made on both poles.
N
The unit to be tested must be isolated against earth
potential.
N
The measurement is equivalent to the earth leakage
current with grounded application parts based on
IEC 601.
N
During the direct method the device under test
is temporarily without PE-connection. Especially devices
without potential-isolation-transformer (sports devices)
have temporarily a voltage of approx. 120 volts on the
metal housing and frame parts. Do not touch the device
under test during this measurement!
