Technical Specifications

Installation Guidelines

• Ensure the control system is powered down before inserting or removing the module from the backplane.
• Handle the module using proper ESD (Electrostatic Discharge) precautions to prevent damage to internal circuitry.
• Ensure the module is fully seated in the designated rack slot to maintain proper backplane communication.
• Verify that all IOP connectors are securely fastened and that the grounding panels are properly bonded to the system ground.
• Maintain adequate ventilation in the cabinet to ensure the module operates within its specified temperature range (0 to 60 deg C).
• Route signal cables away from high-voltage lines and high-EMI sources to maintain signal integrity.
