Safety venting and external / internal
auxiliary control air for fi eld bus, multipole
and RIO modules
46
Safety vent M5, D6, D4, D1/4“
47
Switching between external / internal auxiliary con-
trol air. Connector 12/14 must be closed for internal
auxiliary control air.
CAUTION!
Danger from excessive pressure in the housings!
In the event of error, the safety ventilation connector on the
housing of the fi eld bus / multipole module accumulates the
air and conducts it out of the modules.
The safety ventilation connector must always be connected
in order to maintain the protection class.
In order to guarantee the protective function, the safety
ventilation must not be closed.
