Precautions for use
Before installation, it is necessary to confirm that the power supply voltage matches the rated input voltage of the product to avoid equipment damage caused by overvoltage or undervoltage.
The selection and wiring of bus cables must comply with industrial communication standards to reduce signal interference and ensure communication quality; Suggest wiring separately from power cables.
3. The equipment installation should be firmly fixed on the DIN rail to avoid loose wiring or equipment displacement caused by vibration.
4. During debugging, it is necessary to configure the parameters according to the product manual provided by ABB to ensure consistency with the communication protocol of the bus system and peripheral devices.
5. Regularly check the equipment status indicator lights, promptly detect and handle communication or power supply issues; During maintenance, the power should be cut off first to ensure safe operation.
