Page 3: Unpacking
1. Unpacking Thank you for purchasing our EVSE adapter KEW 8602. The following table is a list of the items included with the instrument. Instrument KEW 8602 x1 Carrying case MODEL 9202 x1 Instruction manual 2. Safety precautions This instrument has been designed, manufactured, and tested...
Page 4 The symbol # indicated on the instrument means that the user must refer to the related parts in the manual for safe operation of the instrument. It is essential to read the instructions wherever the symbol # appears in the manual. # DANGER : is reserved for conditions and actions that are likely to cause serious or fatal injury.
Page 5 # CAUTION ● Use a slightly damp cloth with neutral detergent or water for cleaning. Do not use abrasives or solvents. ● This instrument isn't waterproof. Do not let the instrument get wet. Otherwise, it may cause malfunction. ● If the instrument is wet, make sure to let it dry before putting it into storage.
Page 6: Features
In combination with a Multi-Function tester (not included), this adapter also allows to carry out various electrical installation safety tests from the EVSE socket. KEW 8602 can test EVSE with TYPE 2 plug. When you test EVSE with TYPE 1 plug, optional adapter (KEW 8603) is required. Fig.3-1...
Page 7 Available functions: ●Pre-Test verifies that there is no presence of dangerous voltage at the grounded PE terminal. ●CP (Control Pilot) state check varies Control Pilot signal (resistance between CP-PE) to simulate various vehicle states (A/B/C/D) for EVSE operation check. ●PP (Proximity Pilot) state check varies Proximity Pilot signal (resistance between PP-PE) to imitate various charge cables with different ratings for EVSE operation check.

Page 9: Test Procedures
5.Test procedures 5.1Connection Connect EVSE connection plug of KEW 8602 to an EVSE to be tested (with or without cable as the following examples). Fig.5-1 5.2 Pre-Test After connected with the EVSE under test, touch the touch pad (4) with a bear finger. Normally the PE conductor is connected to ground and has no voltage to ground.

B/C/D) and check the behavior of EVSE. Fig.5-3 1) Set the CP state selector (6) to position “A” (car not connected) and connect KEW 8602 to EVSE. 2) Turn and set the CP state selector (6) to position “B” (car connected).
Page 11 Vehicle states are simulated with different resistances connected between CP and PE conductors. Correlation between resistance and vehicle state is shown in Table 1. Table 1 Resistance between CP-PE and CP terminal voltage depending on vehicle states CP-PE Vehicle State State Description CP terminal voltage Resistance Electric vehicle not connected...
Page 12: Pp (Proximity Pilot) State Check
5.4PP (Proximity Pilot) state check Switch the PP state selector (5) to check the behavior of EVSE with various cable current ratings. Fig.5-4 Rated currents are simulated with different resistances connected between PP and PE conductors. Correlation between resistance and rated current is shown in Table 2.
Page 13: Pe (Earth Fault) Error Simulation
5.6 PE (Earth fault) error simulation With a press of PE error simulation button (8) can simulate the interruption of the PE conductor (or unconnected state). 1) Turn and set the CP state selector (6) to position “C” (car charging) or “D” (car charging with ventilation). 2) Turn the PP state selector (5) to any position other than OPEN.
Page 14 Possible example of performable tests: ① Volt, Frequency, Phase rotation (for 3 Phase EVSE) (1) VOLT (Single-phase) 1) Turn and set the CP state selector (6) to position “C” (car charging) or “D” (car charging with ventilation). Select VOLTS range on KEW 6516/6516BT. KEW 6516/6516BT Fig.5-8 (2) VOLT (3 phase 4 wires) and phase rotation...
Page 15 ② Continuity of protective earthing conductors (PE) Turn and set the CP state selector (6) to position “B”. Select CONTINUITY range on KEW 6516/ 6516BT and check for continuity of the PE conductor, see a possible example of PE test: KEW 6516/6516BT Fig.5-10 ③...
Page 16 ④ Loop / line impedance Turn and set the CP state selector (6) to position “C” (car charging) or “D” (car charging with ventilation). (1) LINE-EARTH LOOP IMPEDANCE measurement Select LOOP ATT on KEW 6516/ 6516BT and connect to measuring terminals: L, N, and PE to conduct 3-wire LOOP impedance test.
Page 17 ⑤ RCD test Turn and set the CP state selector (6) to position “C” (car charging) or “D” (car charging with ventilation). Prior to RCD test, check the type of RCD installed in the EVSE under test. (IEC 60364-7-722 standard states that EVSE should have Type B, Type A or Type FRCDs, and a residual direct current detecting device (RDC-DD) complying with IEC 62955.) KEW 6516/6516BT can test above RCDs: Type A, B, F and also the...
Page 18 ⑥ Earth resistance test (3Wire or 2Wire test) (1) 3-wire test In case the measuring of the earth resistance of the electrical installation which supplies the EVSE under test is needed, Select EARTH range on KEW 6516/ 6516BT and the 3-wire test. See a possible example of Earth resistance test with 3 Wire: KEW 6516/6516BT Fig.5-15...
Page 19 # Safety Warnings for 3-wire and 2-wire Earth resistance tests. -As the main earth conductor has to be temporarily disconnected (just for the earth test), to avoid possible risk of electric shock always use safety glows and switch OFF the power supply prior to disconnect the main earth conductor.
Page 20: Cp (Control Pilot) Signal Output Check
5.8 CP (Control Pilot) signal output check Checking the waveform and amplitude of the CP signal are possible with the connection of CP signal output terminals (3) and an oscilloscope (not included). Oscilloscope Not included Fig.5-17 CAUTION: NEVER apply any voltage to the CP signal output terminals otherwise the KEW8602 and the EVSE may be seriously damaged! These terminals are outputs for CP signal only, not voltage inputs!
