Terminal 37 is suitable for category 3 installations 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 Application Guidelines.
