!Warning
Personal injury or property damage can result.
In hazardous areas, personal injury or property damage can result if you create or
break an electrical circuit during operation of an S7-400/M7-400 (for example, by
means of plug-in connections, fuses, switches).
Do not create or break live electric circuits unless you are certain there is no
danger of explosion.
If you use S7-400 under FM conditions, it has to be mounted in a housing, which
