5. Communication

5.1 Wiring instructions

Cable

Belden 3106 A or equivalent. 22 AWG (0.324 mm

) shielded twisted pair, min. 95 % shield coverage.

Cable shield

Connect the cable shield to earth at one end only.

GND terminal connection

In case of communication problems, the GND terminals of the unit and the external device can be linked to-
gether using a third wire.

CAN bus termination resistor

The size of the terminating resistors should be 120 Ω 1 %, 0.5 W resistor.

Never connect the GND terminal to earth directly or through the shield!

If the GND terminal is connected to a PLC or other device, the GND connection of this device
must be isolated from earth!

Maximum length of the CAN bus line is 400 m.
