Installation Guidelines
CRITICAL WARNING: This device is sensitive to electrostatic discharge (ESD). Always use a grounded wrist strap and work at an ESD-safe workstation. Failure to observe ESD precautions can result in permanent damage to the module.
-
1
De-energize System: Before installation, ensure all power to the PLC rack or chassis is disconnected and locked out according to standard safety procedures (LOTO). Verify absence of voltage.
-
2
Position the Module: Identify the designated CPU slot in the SIMATIC M7-400 rack. Align the module's backplane connector with the corresponding connector on the rack's backplane.
-
3
Seat the Module: Apply firm, even pressure to slide the module into the slot until it is fully seated. The module should click into place, indicating a secure connection.
-
4
Secure the Module: Tighten the retaining screw(s) on the front panel of the CPU to secure it firmly to the chassis. Do not overtighten.
-
5
Connect Interfaces: Connect the MPI communication cable and any other required interface module cables to the appropriate ports on the front of the CPU. Ensure all connections are secure.
