Installation Guidelines

• Backplane Mounting: Ensure the module is properly seated in the Quantum rack and the locking tabs are engaged to guarantee a secure electrical connection to the backplane.
• Field Wiring: Connect 24 V AC signals directly to the module terminals; ensure the wiring is clearly labeled according to the system schematic.
• Isolation: Maintain proper separation between AC input signal wiring and low-voltage DC or communication cabling to prevent inductive coupling and interference.
• Grounding: Verify that the common return paths are correctly established for the AC signal circuits to ensure accurate input detection.
• Commissioning: Use the PLC configuration environment to verify the input addressing and ensure that each channel is functioning as expected before commissioning the system.
