3.5.3 Mounting, dimensions and electrical connection

The input modules can be plugged only on spring-type TU582-S I/O Terminal Unit. The unique mechanical
coding on I/O Terminal Units prevents a potential mistake of placing the Non-safety I/O module on Safety I/O
Terminal Unit and the other way around.
Installation and maintenance have to be performed according to the technical rules, codes and relevant
standards, e.g. EN 60204 part 1, by skilled electricians only.
