Procedure
1. Connect the installation tester to the device via the test socket or the 4 mm test sockets.
2. Select the desired positions of the rotary switches.
– “PP-Status/State”: switch position “N.C.”
– “CP-Status/State”: switch position “A”
3. Connect the device to the output of the charging station (EVSE) via the Type 2 connector.
4. Use the installation tester to perform the prescribed safety tests in a voltage-free condition
at the output of the charging station (EVSE).
5. Simulate the different charging states using the switch positions of the rotary switches “PP-
Status/State” and “CP-Status/State” and check the feedback from the charging station
(EVSE).
6. Use the installation tester to perform the prescribed safety tests at the output of the charging
station (EVSE) with the mains voltage being applied. For this, select the desired positions of
the rotary switches at the device.
– “PP-Status/State”: switching position according to the maximum charging current from
13 to 64 A
– “CP-Status/State”: switch position “C” or “D”
7. Before disconnecting the device from the charging station (EVSE), set the rotary switch
“CP-Status/State” to the switch position “A”.

Testing with an oscilloscope
You can measure the CP signal of the charging station (EVSE) with an oscilloscope via the
BNC socket of the device.
Via the duty cycle, the charging station (EVSE) gives the electric vehicle (EV) the maximum
current value that can be drawn from the charging station. For further information, refer to
Table A7 of DIN EN 61851-1 (VDE 0122-1).
• D: Duty cycle
• PW: Pulse duration
• T: Period duration
