6. Connection for the instrument and the device under test
When the DUT is equipped with a mains plug, use test socket, RPE -Test lead
and PE/2mA terminal for a measurement of protective conductor resistance,
insulation resistance and equivalent leakage current of DUT. But if not, connect
the DUT to L/N and PE/2mA terminal which are connected inparallel to the test
socket with the optional cord. Use one of the following test set ups, depending
upon the type and condition of the DUT.
6. 1 Safety Class I DUT with Mains Plug
6. 2 Safety Class II DUT with Mains Plug
6. 3 DUT Without Mains Plug or Safety Class lll DUT
6.4 3-Phase DUT
