Maintenance Recommendations

• Regularly inspect the tightness of all wiring terminals to prevent loose connections, poor contact, or signal interference caused by vibration and long-term operation.
• Prior to performing maintenance operations, either cut off the relevant power supply or utilize the hot-swappable feature to avoid electrical faults, short circuits, or system malfunctions.
• Periodically clean dust and debris from the module surface and surrounding areas to maintain adequate ventilation and heat dissipation, preventing performance degradation or component damage caused by overheating.
