PE Error (Earth Fault) simulation
When the PE Error button (no. 10), is pressed the interruption of the PE conductor is
simulated. The charging process should be aborted and further charging is prevented.
Phase indicator
The phase indicators are LEDs, one LED for each phase (no. 3). When the test adapter
is connected to the charging station and phase voltages are present at the charging
connector, the LED indicators will illuminate.
In the case where the neutral (N) conductor is not present or it is interrupted,
LED indicators will not indicate possible voltage presence at L1, L2 and L3
conductors. The LED indicators are not intended to be used for phase sequence
testing.
• When testing a single phase charging station, only one LED will illuminate.
Mains socket
The mains socket (no. 11) is connected to L1, N and PE conductors of the charging
station. External load can be connected to the socket. This output is intended for
measuring purposes only and offers the possibility to check the electric power meter
functionality. It is not allowed to supply anything else through the socket. The max.
current is limited to 10 A with an T10A/250V, 5×20 mm fuse located in the back
compartment of the Adapter.
Measuring terminals L1, L2, L3, N and PE
Measuring terminals (no. 1 and 2) are directly connected to L1, L2, L3, N and PE
conductors of the tested charging station. It is permitted to use these for measuring
purposes only. It is not allowed to draw current over a longer period or supply
anything else.
An appropriate measurement instrument is needed.
For electrical safety checks, set the CP state to match the EVSE ratings.
To check the functions of the EVSE charger switch the CP state through from A to C
for chargers without ventilation and from A, through to D for chargers with ventilation.
With reference to table 2 and the EV charger’s manual ensure that the charger
performs as it should.
To perform a loop test turn the CP switch to either position C or D (according to the
type of charger).
Connect your tester into the KEWEVSE adapter and perform a low current loop test.
To test the RCD and 6mA DC protection, connect your tester to the KEWEVSE
adapter. Turn the CP switch to either position C or D (according to the type of
charger). Depending on the sequence of tests performed by your tester after each trip,
reset the RCD and then turn the PP state switch to the A* position and then back to C
or D (whichever is appropriate).
* Some EVS equipment does not require you to do this.
Fuse replacement
The fuse (T10 A / 250 V, 5 x 20 mm). If no voltage is present between the L and N terminals
of mains socket when the charging connector is connected to the charging station and the
charging station is in charging mode, it is possible that mains socket fuse is broken.
• In that case disconnect adapter from the charging station
• Open cover from the back of the adapter (appropriate screwdriver is necessary)
• Locate and replace fuse with the fuse of the same type.
• Return back cover of the fuse compartment.
Cleaning
If the instrument is dirty after daily usage, it is advised to clean it by using a humid cloth and
a mild household detergent. Prior to cleaning, ensure that instrument is switched off and
disconnected from external voltage supply and any other instruments connected (such as
UUT, control instruments, etc.).
Never use acid detergents or dissolvent for cleaning.
