Installation Guidelines
Ensure the CompactLogix rack is powered down before inserting or removing the MVI69E-MBS module.
Slide the module into the appropriate slot on the backplane and secure it using the integrated locking mechanism.
Use shielded twisted-pair cabling for all serial connections to minimize electromagnetic interference (EMI).
Ensure proper grounding of the serial cable shield at one end to prevent ground loops.
Configure the module using the ProSoft Configuration Builder via the dedicated configuration port before full system deployment.
Verify that the module status LEDs indicate normal operation after power-up.
