6. Installation and Maintenance

Installation Notes

• Isolation Confirmation: Confirm that the module is of Isolated or External type to avoid direct connection with low-voltage equipment.
• Backplane Connection: Ensure that the rack backplane power cable is firmly connected and the module direction is correct (backplane direction).

Maintenance Recommendations

• Regular Calibration: Regularly check the sensor calibration to ensure accurate process variable readings.
• Cleaning Maintenance: Keep the module terminal block clean to prevent poor contact caused by dust.
• Maintenance Recording: Record the module operating hours through the 3500 configuration software to facilitate preventive maintenance.
