Equivalent Leakage Current Measurement

•
Measure the equivalent leakage current according to ARTD-002.731.17... (safety-relat-
ed regulations on installation and maintenance). The measured values is to be entered
and to be evaluated in the maintenance protocol. The limit values of 2 mA must not be
exceeded.
NOTE
SIE Measured value
MOBILETT Plus HP
It is required to measure the equivalent unit leakage current with
the main switch set to "M" (mains operation) and to "C" (battery
charge). The higher value has to be taken down and evaluated.
Evaluate the results by comparing the first measured value with
the corresponding value of preceding maintenance procedures or
safety checks. A sudden or unexpected increase of the measured
values may indicate that an error occurred in the primary circuit of
the power supply (damaged insulation, damage caused by water
ingress or humidity, etc.) – even if the limit value of 2 mA is not ex-
ceeded.
