8.3 Operation of a charging station to be tested
8.3.1 PE Pre-test
•
Do not touch the PE terminal on the front power socket until the PE pretest is successful.
•
The PE Pre-Test is a safety feature of the test adapter, it allows the operator to test the PE
conductor for possible presence of dangerous voltage against earth.
•
In normal circumstances, the PE conductor is connected to earth and therefore has no voltage
against earth however if the PE conductor is not connected to earth [e.g., connected to phase by
mistake or PE is interrupted] the situation may be hazardous.
•
Test procedure:
1-First connect the adapter firmly to the charging station.
2-Then touch the probe with a bare finger.
•
If light indicator is illuminated, then dangerous voltage is present at PE conductor, stop further
testing immediately and check fora possible wiring fault of the tested PE conductor
•
In case of this error, PE terminal carries hazardous voltage, there is a high risk of electric
shock to the operator and other persons nearby!
•
Possible errors are, PE interrupted/not connected/PE carries voltage [e.g., connected to phase].
•
Do not wear gloves while performing this test and ensure a proper connection to earth.
•
In case of improper connection to earth [e.g., isolated placement of your body] this indication
may be not reliable.

8.3.2 Proximity Pilot IPP) State (Cable Simulation)
•
With the PP State rotary switch various current capabilities of the charging cable can be
simulated when the test adapter is connected to the charging station.
•
Current capabilities are simulated with different resistances connected between PP and PE
conductors. Correlation between resistance and current capability of the charging cable is shown
in Table below:
