Operation of electrical vehicle tester
8.1
PE test
This test can be used to determine whether there is any external voltage on the protective earth
conductor. Do not touch the protective conductor connection before the PE test is completed.
Proceed as follows for the test:
1.
Connect the adaptor to the charging station.
2.
Touch the PE contact surface.
If the PE test signal lamp lights up during the test, there is a risk of electric shock as there is an
external voltage on the protective conductor. No further work or tests should be carried out until
this fault has been rectified.
Note:
Make sure that you do not wear gloves during the test and that your hands are clean. This
test does not guarantee absence of voltage.
8.2
PP test signal
The PP test rotary selector switch can be used to simulate the cable type. For this purpose, a
specific resistor will be connected between the PP cable and the protective earth conductor. This
can be seen in the following chart:
