    IR test on DOL to motor AM2

    Does anybody know if you only to an IR test on the cables that you have pulled in from the DOL to the motor on the AM2? So, you would just do L1-E,L2-e, L3-e, Then L1-L2, L1-L3, L2-L3? Obviously from the DOL to motor you will only pull in brown, black, grey then and earth with no neutral.
