Terminals 2 and 6 as well as 3 and 7 are bridged internally. Please note that
the max. permissible bridge current is 5 A.
ƒ
Both the I/O supply and the electronic supply are protected against overload
internally by a fuse. When the fuses have been tripped, the main supply of
the bus coupler (EPM−S700) must be replaced (

Stop!
Housing breakage in the case of a too high tightening torque of the securing
screws
If the connector securing screws are tightened too firmly, the housing may
break.
Possible consequences:
ƒ
The plug connection is no longer secured against tension.
ƒ
Enclosure IP20 of the module which is warranted can no longer be
guaranteed.
Protective measures:
ƒ
Tighten securing screws without using force (max. 40 Nm).
