11.2.2. IP54 field bus connection
For the field bus connection the 5-pole M12 Micro-Style plug-in connector (plug) as specified by the DeviceNet
is used with the following pin assignment.
Pin No. Signal name
1 Drain (shielding)
2 not used
3 GND
4 CAN HIGH
5 CAN LOW
The bus drivers are supplied internally via a voltage source which is galvanically isolated from the supply voltage.
For this reason it is not necessary for separate voltage to be supplied from the bus via pin 2 and pin 3.

11.2.3. IP54 terminating circuit
When installing a DeviceNet system, ensure that the terminating circuit of the data lines is correct. The circuit pre-
vents the occurrence of interference caused by signal reflection in the data lines. The trunk line must be terminated
at both ends with resistors of 120 Ω each and 1/4 W power loss.
11.3. Position of the DIP switches
The DIP switches are used to make field bus module settings.
NOTE!
Changes made to the switch settings only take effect after the field bus module has been reset. Set the DIP
switch through the film using a screwdriver (the film is very durable).
'ON' setting = DIP switch to the right
