Insulation Measurement; Continuity Measurement - Chauvin Arnoux CA 6651 Manual De Instrucciones

2.3.3. CHECK OF THE PROTECTIVE CIRCUIT-BREAKER
After checking the connection to earth, check the operation of the differential circuit-breaker (RCD:
Residual Current Device).
„ Connect the multifunction tester in the same way as for an earth measurement.
„ Perform an RCD ramp test. For this, refer to the operating instructions of the multifunction tester.
„ In the case of a three-phase network, reset the RCD and repeat the test with the wire red connected
to phase L2. Then repeat with phase L3.
At the end of the test, leave the RCD open in order to perform the no-voltage insulation test.

2.3.4. INSULATION MEASUREMENT

This test must be performed with no voltage. None of the indicators of the CA 6651 must be lit.
„ Connect the L1, L2, L3, and N terminals together and make an insulation measurement with respect
to the PE. For this, refer to the operating instructions of the multifunction tester.
The insulation resistance must be greater than 500kΩ for a 230V single-phase network and greater than
1MΩ for a 400V three-phase network.

2.3.5. CONTINUITY MEASUREMENT

This test must be performed with no voltage. None of the indicators of the CA 6651 must be lit.
„ Connect the PE terminal and the earth of the installation that supplies the charging terminal to the
multifunction tester and make a continuity measurement.
Refer to the operating instructions of the multifunction tester.
Do not forget to reset the RCD at the end of the test.
