Decentral Drive FCD 302 Operating Guide, and the VLT® Motion Control Tools MCT 10 Operating Guide available as they
contain important information that is not included in this manual.

for the connections between the safety option's safe output S37 and terminal 37 on the drive.
-
To connect the safety device correctly to the safety option, read and follow the instructions in this manual.
NOTICE
The safety option is exclusively intended for use in option slot B.
