VIII. Usage Precautions

Installation / Disassembly must be performed after the system is completely powered off to prevent static electricity and short circuit damage

Ensure stable 24V DC power supply and good grounding The servo cables are made of shielded wires to reduce signal interference.

When replacing, check the hardware version and component number (DF8203498).

Regularly clean the boards to prevent short circuits caused by dust and metal debris.

Avoid overloading the servo ports and prohibit short-circuiting the output terminals.
