The following faults can be simulated using the test adapter with mains supply to a charging cable (also possible without additional test instrument):

• Wire reversal
• Failure of individual conductors (undervoltage detection)
• Interference voltage in the protective conductor due to connection of the phase conductor to the protective conductor (PE-UEXT switch setting)

Evaluation of the charging cable’s reaction to each respective fault is strictly visual:

• ICCB active or inactive (indicator lamp on the ICCB)
• Fault indication by means of LEDs on the test adapter

The following additional tests are possible after connecting a recommended test instrument to the test adapter:

• Single measurements
• Measurement of the charging cable’s protective conductor resistance using the test instrument’s RPE function
• Measurement of the charging cable’s insulation resistance using the test instrument’s RINS function
• Tripping test for the RCD in the ICCB with nominal residual current using the test instrument’s IF function
• Measurement of time to trip for the RCD in the ICCB using the test instrument’s IdN function
• Measurement of resistance coding

Test sequences for convenient measurement and report generation

Two preset test sequences are included in the respective test instruments:

• Mode 2 charging cable
• Mode 3 charging cable
• The test instrument runs through all test steps semi-automatically.
• Each test step is evaluated and assessed by the user (go/no-go) for later documentation.

• Testing of charging cables in accordance with DIN VDE 0701-0702 and the manufacturer’s specifications using a guided test sequence with a recommended test instrument
• Testing of mode 2 and mode 3 charging cables
• Testing of connector cables with country-specific plug (type 1 plug etc.)
• Function test, i.e. tripping test by means of simulating the following faults: interruption, reversed wires and PE to phase
• Measurement of protective conductor current with current clamp transformer as accessory
• Measurement of protective conductor and insulation resistance per DIN VDE 0701-0702 with a recommended test instrument
• Tripping test with nominal residual current and measurement of time to trip with a recommended test instrument
• Evaluation and documentation of the individual test steps with a recommended test instrument
• Simulation of vehicle state per EN 61851-1/VDE 0122-1
• Testing of resistance coding for vehicle inlets and vehicle connectors per EN 61851-1/VDE 0122-1
