1) Terminals 27 and 29 can a lso b e p rogramme d as output.
2) Exc ept safe stop input Terminal 37.
3) Terminal 37 is only available in FC 302. It can only be used as safe stop input. Terminal 37 is suitable
for categ ory 3 insta llations according to EN 954-1 (safe stop according to category 0 EN 60204-1) as
required by t h e 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 618 00- 3, and EN 954-1. For correct and s afe
use of the Safe Stop function, follow the related information and instructions in the Design Guid
e.
