Notes:
The autotest sequence is immediately stopped if any incorrect condition is
detected, e.g. excessive Uc or trip-out time out of bounds.
Auto test is finished without x5 tests in case of testing the RCD types A, F with
rated residual currents of I
n = 300 mA, 500 mA, and 1000 mA. In this case auto
test result passes if all other results pass, and indications for x5 are omitted.
Tests for sensitivity (I ,, steps 7 and 8) are omitted for selective type RCD.
