Protective conductor measurement

•
Perform the protective conductor measurement according to ARTD-002.731.17...
"Safety technical information for installation and start-up ".
Protective conductor resistance

Equivalent leakage current measurement

•
Perform the equivalent leakage current measurement in accordance with
ARTD-002.731.17...
"Safety technical information for installation and start-up" .
Initial measurement
When measuring the equivalent leakage current, an initial measurement as well as repeat
measurements are taken. The purpose of these repeat measurements is to detect devia-
tions from the "initial" measurement and thus to recognize changes in the safety structure
of the system as early as possible.
The initial value measured may not exceed the maximum value of 2 mA.
Conform to the measurement setup shown in Fig. 2.
During the measurement, POLYMOBIL Plus must be switched on. Therefore, when using
the BENDER Safety tester, it must be set to manual measurement.
The "initial" value should be entered in the test protocol at the end of these start-up
instructions.
