Installation Guidelines
CRITICAL WARNING: Disconnect all power sources from the S7-400 rack and follow all Lock-Out/Tag-Out (LOTO) procedures before attempting to install or remove this module. Failure to de-energize the system can result in electric shock, equipment damage, and unintended machine operation. This module contains components sensitive to electrostatic discharge (ESD).
-
1
Ensure the S7-400 rack is completely de-energized and verified to be in a zero-energy state.
-
2
Use a grounded wrist strap and handle the CPU module by its edges or front plate to prevent ESD damage to sensitive electronics.
-
3
Select the designated CPU slot in the S7-400 rack. Align the module with the top and bottom guide rails.
-
4
Slide the module into the rack until its backplane connector makes firm contact with the rack's bus connector. Ensure it is fully seated.
-
5
Tighten the retaining screws on the front panel of the module to secure it to the rack frame. Do not overtighten.
-
6
Connect the MPI/DP communication cable to the corresponding port on the front of the CPU. Ensure the connector is securely fastened.
-
7
Once all modules are installed and connections are verified, remove LOTO devices and re-apply power to the system for commissioning.
