Precautions

• During installation, it should be installed in accordance with the standard guide rail installation method to ensure firm installation, and attention should be paid to leaving sufficient heat dissipation space around the module.
• When connecting the power supply and signal lines, it is necessary to ensure that the power supply voltage meets the module's requirements and that the wiring is correct to avoid module damage caused by wrong wiring.
• Although the module has electrical protection functions, it is still necessary to avoid using it in environments with strong electromagnetic interference. If the on-site electromagnetic interference is strong, corresponding shielding measures must be taken.
