Place the black probe of the digital multimeter on the negative insulator A and the red probe on the power
contact B1 of contactor B. Read the voltage V2 between the power contact B1 of the contactor B
corresponding to the drive and the negative insulator A; the voltage must be equal to or very slightly lower
than the value V1.
