Repeat measurement
When maintenance or repair work is performed on the primary power supply circuit (e.g.,
repairs to the power-on circuit or replacement of the line filter), the leakage current mea-
surement must be repeated.
The same measuring conditions as in the first measurement apply.
Record and assess the highest value determined in the repeat measurement in the exist-
ing system leakage current report.
This value must not exceed the permissible leakage current values according to DIN VDE
0751-1/2001-10, Table F.1, line "leakage current for devices according to remarks 1 and
3", of 2.5 mA.
Measure and record the current line voltage. If the measured line voltage deviates from
the nominal voltage, correct the measured value to the value corresponding to a mea-
surement at the nominal value of the line voltage. This must also be documented.
Document the measuring procedure (differential measurement or direct measurement)
and the measuring device used (designation and serial number).
NOTE
MOBILETT XP Digital
For evaluation purposes, the first measured value and the values
documented during maintenance or safety checks must be com-
pared to the measured values. A sudden or unexpected increase
in the measured values may indicate that a fault has occurred in
the primary power supply circuit (damaged insulation, damage
from moisture, defective interference suppressor, etc.) - even if the
limit value of 2.5 mA is not exceeded.
