Installation Guidelines

CRITICAL WARNING: This is obsolete hardware. Verify compatibility with existing CPU, I/O modules, and programming software before installation. Improper integration can lead to system malfunction or data loss. Always handle with appropriate ESD precautions.
  1. 1
    De-energize Equipment: Before installation, ensure all power to the control cabinet is disconnected and locked-out/tagged-out (LOTO). Verify the absence of voltage with a properly rated meter.
  2. 2
    Secure Mounting: Mount the central controller chassis securely onto the backplane or DIN rail within the control panel. Ensure there is adequate clearance for ventilation and cable routing.
  3. 3
    Establish Ground Connection: Connect the chassis to the main panel protective earth (PE) ground bus using a low-impedance conductor. A reliable ground connection is critical for noise immunity and safety.
  4. 4
    Connect Power Supply: Connect the 24V DC source power to the designated input terminals on the integrated power supply. Verify correct polarity before energizing the system.
  5. 5
    Install Modules: Carefully insert the SIMATIC S5 CPU and I/O modules into the appropriate slots, ensuring they are fully seated and secured.
