Only the manufacturer can perform the type test and production test; users can also perform
the field test.
Preconditions for performing the field test:
Tests (A) & (B)
●
Connect the input terminals with one another
●
Connect the output terminals and PE together
Test (C)
●
Connect the output terminals with one another and measure with respect to PE
