Manual, 09/2018, L1V30368969105-01

Mounting positions and switching behavior

●

Auxiliary switches mounted at position 1 or at contact number 1 or 5 function as leading

switch-off auxiliary switches.

●

Auxiliary switches which are mounted at position 2 or at contact numbers 2 / 6, 3 / 7 and

4 / 8 (position 4 / 8 only with sizes 4 and 5) operate simultaneously with the main switch.
