Information on measuring the leakage current 0
Observe the instructions in the "Safety Rules for Installation and Repair"
(ARTD-002.731.17 ...).
WARNING
Electrical voltage!
Non-compliance can lead to severe injury and even death.
¹ The leakage current measurement may be performed on
systems of protection class I only after the protective
conductor test has been passed.
Initial measurement
Perform the leakage current measurement after completion of all work.
Perform the measurement according to DIN VDE 0751, Part 1 (see ARTD-002.731.17....),
and record the determined value as the first measured value.
Measurement of the leakage current according to the differential current method (mea-
surement setup according to (Fig.7/p.22)) must be given preference, since this method
is not dangerous to the person performing the measurement and other persons.
However, please note the minimum resolution of the leakage current measuring device
and any additional manufacturer information restricting the use of the measuring device.

current method in compliance with DIN VDE 0751-1/2001-10, Fig. C6 for protection
class I.
