[9.C4] Equivalent (alternative) leakage current IEDL measurement<br />
[9.C5] Leakage current measurement<br />
direct method: measurement in PE - line<br />
difference current method: supply/return line<br />
maintenance & safety inspections<br />
N Impedance measurement, indicating the current in the<br />
Protective¬Earth¬Cable<br />
N The measuring is to be performed by a measuring device<br />
for leakage current measuring according to VDE<br />
0701/0702 (sports <strong>and</strong> fitness <strong>machine</strong>s) or VDE<br />
0751/IEC 601-1 (medical devices).<br />
N The measurement is equivalent to the single fault earth<br />
leakage current based on IEC 60601.<br />
N The measuring is to be performed by a measuring device<br />
for leakage current measuring according to VDE<br />
0701/0702 (sports <strong>and</strong> fitness <strong>machine</strong>s) or VDE<br />
0751/IEC 60601-1 (medical devices).<br />
N The leakage current of the equipment is to be measured<br />
under operating conditions, if -despite closed switchingnot<br />
all isolations are seized.<br />
N Measurements must be made on both poles.<br />
N The unit to be tested must be isolated against earth<br />
potential.<br />
N The measurement is equivalent to the earth leakage<br />
current with grounded application parts based on<br />
IEC 60601.<br />
N During the direct method the device under test<br />
is temporarily without PE-connection. Especially devices<br />
without potential-isolation-transformer (sports devices)<br />
have temporarily a voltage of approx. 120 volts on the<br />
metal housing <strong>and</strong> frame parts. Do not touch the device<br />
under test during this measurement!<br />
