equipment rooms and in a dry environment (IP20 degree of protection). These enclosures,
cabinets or electrical equipment rooms must only be accessible with a key or tool. Access

Installation location
Install the ET 200SP distributed I/O system into a suitable housing/control cabinet with
sufficient mechanical strength, fire protection and at least IP54 degree of protection
according to EN 60529, and take into consideration the ambient conditions for operating the

Installation position
You can mount the ET 200SP distributed I/O system in any position. The preferred mounting
position is horizontal mounting on a vertical wall. The ambient temperature may be restricted
in certain installation positions. You will find more information in the section Mechanical and
