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, signaling contact and PE with one another
Test (C)
● Connect the output terminals and signaling contact with one another and measure with
respect to PE
