EXAMPLE OF SEPARATION TEST BETWEEN ELECTRICAL CIRCUITS

Insulation or safety transformer

separating the circuits

TEST BETWEEN ACTIVE PARTS

Connect an instrument probe to

one of the two conductors of the

separated circuit and the other to

one of the conductors of a non-

separated circuit.

TEST BETWEEN ACTIVE PARTS

AND EARTH

Connect an instrument probe to

one of the two conductors of the

separated circuit and the other to

the equalizing potential node. This

test must be performed for SELV

circuits or circuits with electrical

separation only.
