Connecting the device to a büS / CANopen network
For a correct operation of the device, use a 5-pin M12 female connector in stainless steel with shield con-
nection. The büS cable that is available from Bürkert has an external diameter of 8.2 mm.
→
Make sure that the büS cable passes through the 5-pin M12 female connector.
→
Observe the specifications for the cable and conductors, that are given by the manufacturer of the 5-pin
female connector.
The 5-pin M12 male connector (A-coding) is used to connect the device:
•
To a 12...35 V DC power supply and/or
•
To the büS / CANopen network.
→
To connect the device, remove the screwed plug of the 5-pin M12 male connector and store the screwed
plug in a safe and clean place.
Risk of damage to the device if an M12 connector is unused.
▶
Put a screwed plug on all the unused M12 connectors.
Malfunction of the internal and external communication if the 5-pin M12 male connector is not used
to connect the device to a büS fieldbus or a CANopen fieldbus.
▶
Make sure pin 4 (CAN_H) and pin 5 (CAN_L) are both contact free if the 5-pin M12 male connector
is not connected to a büS fieldbus or a CANopen fieldbus.
→
If the device is connected to a büS network or to a CANopen network and installed at one end of the
büS network or of the CANopen network, either install one or two 120 Ω termination resistors in the line
or activate the device internal termination resistor: see chapter
. The büS or CANopen line must be
adapted to reached 60 Ω.
If a device with two 4-pin M12 female connectors (Ethernet device variant) is connected to an Eth
-
ernet network, you must connect it to a büS / CANopen network for the configuration of the device
with the software Bürkert Communicator.
