VIII. Usage Notes

Installation / disassembly must be completely powered off, and an anti-static wrist strap must be worn

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

I/O cables must use twisted shielded cables, with the shield layer grounded at one end

Output ports must not be short-circuited to avoid exceeding 0.5A/channel load

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

The working environment should avoid high temperature, high humidity, and corrosive gases

When replacing, check the model JANCD-1021 REV.A0 and the part number (DF8202440)
