VIII. Usage Notes

Installation / disassembly must be performed after the system is completely powered off to prevent static electricity and short circuits from causing damage

Ensure stable 24V DC power supply and grounding resistance < 4Ω

Servo / encoder cables must use shielded cables， with the shield connected to one end only

When replacing， check the part number (DF8202935-A1) and hardware version (Rev.A)

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

Do not overload drive the servo ports， and do not short-circuit the output terminals

Avoid high temperature， high humidity， and corrosive gases in the working environment
