An appropriate terminating resistor kit, WRC part number RM121DN, is included with your JDM.
Important
: Per the DeviceNet spec -- do not terminate devices on drop lines.
3.5.2 DeviceNet Connection Wiring
The supplied DeviceNet connection plug accepts cable sizes from 12 AWG - 24 AWG. The
maximum wire size (12 AWG) has an area of 653O circular mils and the smallest (24 AWG) has an area
of 3265 circular mils.
Where not prohibited by local government or wiring regulations or company policy, multiple wires
can be inserted each connection point on the plug as long as the total wire area does not exceed that of a
12 AWG wire. Use the chart below as a guide.
Phoenix Contact recommends using the same size wires be used when connecting more than
one wire in a screw termination.
UL may require the use of crimped ferrules to connect multiple wires together.
