Installation Guidelines

• Ensure the PLC rack power is disconnected before installing or removing the module to prevent electrical damage.
• Verify that the module is firmly seated in the backplane connector to ensure proper communication with the CPU.
• Use shielded twisted-pair cabling for analog signals to minimize electromagnetic interference (EMI) and signal noise.
• Route analog signal cables away from high-voltage AC power lines and inductive loads.
• Ensure proper grounding of the module chassis to the system common ground to maintain signal integrity.
• Maintain adequate clearance around the module to allow for proper airflow and cooling within the control cabinet.
