Protective conductor test
SIE
Protective conductor resistance
•
Perform the protective conductor test with the system closed according to
ARTD-002.731.17
...
Document and evaluate the determined values indicating the
measuring points.
The protective conductor resistance must not exceed 0.2 Ohms.
NOTE
Evaluate the results by comparing the first measured value to the
corresponding values documented during preceding maintenance
procedures or safety checks.
A sudden or unexpected increase in the measured values may in-
dicate a defect in the protective conductor connections (protective
conductor or contacts) - even if the limit value of 0.2 Ohms is not
exceeded.
SIE
Leakage current
•
Measure the leakage current according to
ARTD-002.731.17
.... Document and evalu-
ate the determined values. The limit value of 2.5 mA may not be exceeded.
NOTE
Evaluate the results by comparing the first measured value to the
corresponding values documented during preceding maintenance
procedures or safety checks.
A sudden or unexpected increase of the measured values may in-
dicate that a fault has occurred in the primary circuit of the power
supply (damaged insulation, damage caused by water ingress or
humidity, defective interference suppressor, etc.) - even if the limit
value of 2.5 mA is not exceeded.
