If the cable length is longer than 20/30cm, it must be
twisted and shielded. The shield must be connected to
ground on both ends, utilising U-clamps to the zinced
panel of the electrical box.

Cable capacitance: Max 60 nF/km.
Impedance characteristics : 100...120Ω.
Lead resistance (loop): 159,8 Ω/km.
The length depends upon the transmission speed:
• 1000kbit/s 20m Max;
• 500kbit/s 70m Max;
• 250kbit/s 115m Max.

Micro USB B 5P to USB A type male.
The cable length must be shielded and 3m Max.
Notes:
• Avoid crossing, overlapping and twisting cables together. If it is absolutely necessary to cross
them, do so at 90°.
• Use only copper conductors for cabling.
