For user terminal wiring requirements, please refer to Figure 1-5. when wiring, please pay attention to the following 7 aspects. 1. It is recommended that twisted shielded cables be used for the analogue outputs and that the cables be routed away from power cables or other wires that may cause electrical interference. 2. Use a single point of earth at the load end of the output cable. 3. If there is electrical noise or voltage fluctuations in the output, connect a smoothing capacitor (0.1μF to 0.47μF/25V).
