Installation Guidelines

Proper installation is crucial for the reliable operation of the SIMATIC S7-400H system bundle. Adhere to standard industrial practices and safety protocols:

1. De-energization: Ensure all power to the installation area is disconnected and locked out before beginning any work.
2. Mounting: Securely mount the UR2-H rack in a suitable control cabinet, ensuring adequate ventilation and clearance for cable routing and maintenance.
3. Power Supply Connection: Connect the two PS 405 power supplies to the appropriate 24/48/60 V DC sources, ensuring correct polarity and proper grounding. Verify that power cables are correctly terminated and secured.
4. CPU and Module Installation: Insert the CPU 417-5H processors and sync modules into their designated slots within the UR2-H rack. Ensure all modules are firmly seated.
5. Sync Cable Routing: Connect the provided 1-meter sync cables between the sync modules of the redundant CPUs. Route these cables to minimize electromagnetic interference and mechanical stress.
6. Memory Cards and Batteries: Install the two required memory cards into the CPU 417-5H processors and the four backup batteries into their respective compartments.
7. Grounding and Shielding: Establish a robust grounding connection for the entire system to the control cabinet's ground bus. Implement proper shielding for signal cables to prevent noise interference.
8. Cable Management: Route all power, communication, and I/O cables neatly, separating high-voltage and low-voltage lines to prevent interference. Use cable ties and conduits where appropriate.
9. Power-Up and Testing: After all connections are verified, re-energize the system and perform initial diagnostic checks and functional testing according to Siemens' commissioning procedures.
