5. Installation and Maintenance Recommendations

Pre-Installation Preparation

• Ground Check: Use an insulation tester to confirm that the rack grounding resistance is less than 1Ω to ensure good system grounding.
• Connector Check: Inspect that the backplane pins are not bent and the module gold fingers are free of oxidation; clean with isopropyl alcohol (IPA) if necessary.
• Cable Preparation: Prepare shielded twisted-pair cables (such as Belden 8761) for analog signal transmission to ensure signal shielding performance.

Maintenance

• Regular Calibration: It is recommended to calibrate the module with a process calibrator (such as Fluke 744) every 12 months.
• Tightening Check: Regularly check the terminal tightening torque (recommended 0.6 N·m) to prevent loose connections caused by vibration.
• Replacement Requirements: When replacing the module, re-download the configuration parameters through dedicated software (such as ToolboxST) to ensure the system parameters match the new module.
