Installation Guidelines

• Ensure the system is powered down before inserting or removing the module from the carrier.
• Verify the rotary keying position (B4) matches the terminal block to prevent hardware damage.
• In hazardous areas, ensure all non-sparking field circuits are de-energized prior to maintenance.
• Maintain proper ventilation to stay within the -40 to +70 deg C operating range.
• Use shielded cabling for field connections to minimize EMI interference.
• Handle with standard ESD precautions to protect internal circuitry.
