Siemens SIMATIC IPC677E Operating Instructions Manual page 107

Procedure
1. Loosen the marked screws and remove the heat sink.
2. Release the lever of the processor bay and tilt it all the way back. The bay releases the
processor.
3. Remove the processor by grabbing the marked rails on the side. Do not touch the
processor and its connections in the process (see "ESD guidelines" under General safety
instructions (Page 25)).
Note
The contact springs of the socket are highly sensitive to mechanical damage, e.g. caused
by an incorrectly inserted CPU or foreign objects, and their entire surface may only touch
the contact side of the processor flat.
