Note
The CSM 1277 does not have a feedthrough for the backplane bus. It must therefore be mounted
either at the start or end of the S7-1200 station!
1. Place the upper guide at the top of the CSM housing in the 35 mm DIN rail (DIN EN 60715
TH35 ).
2. Push in the lower part of the CSM 1277 onto the rail until it locks in place.
