VIII. Usage Notes

Installation / disassembly must be completely powered off, wear anti-static wrist straps to prevent static discharge

Ensure stable 24V DC power supply, grounding resistance < 4Ω, avoid common-mode interference

Servo / encoder cables must use twisted shielded cables, single-ended grounding of the shielding layer

When replacing, check the component number DF8203297-A0 and the hardware version (Rev.A)

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

Do not short-circuit the servo output ports, strictly prohibit overloading the drive of the servo axis

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