Installation and Maintenance
Pre-installation preparation: Ensure the control cabinet is grounded and powered off. Plan cable routes to separate power and signal wires by at least 100 mm to reduce EMI. Use a torque screwdriver to fasten terminals to 0.8–1.2 N·m, as per ABB’s guidelines.
Maintenance recommendations: Inspect terminals quarterly for loose connections or oxidation. Use a multimeter to verify continuity in high-critical paths. For retrofits, label cables before disconnecting to avoid re-wiring errors. Clean the module with a non-conductive brush to remove dust, ensuring proper heat dissipation in high-temperature environments.
