5. General Specifications
2) Except safe stop input Terminal 37.
3) Terminal 37 can only be used as safe stop input. Terminal 37 is suitable for category 3 in-
stallations according to EN 954-1 (safe stop according to category 0 EN 60204-1) as required by
the EU Machinery Directive 98/37/EC. Terminal 37 and the Safe Stop function are designed in
conformance with EN 60204-1, EN 50178, EN 61800-2, EN 61800-3, and EN 954-1. For correct
and safe use of the Safe Stop function follow the related information and instructions in the
Design Guide.
