Connect a 24-volt DC source to the DC power input. The delivery includes a 2-pin connector.
Conductor cross-sections of 0.2 mm² (AWG24) to 6 mm² (AWG10) can be used.
Recommended connecting cable: flexible CU strand, LiY, 4 mm².
The DC input is protected against incorrect polarity and overload. The associated fuse is
located on the inside of the device and is not accessible from outside of the device.
!
Warning!
Never connect the positive te with ground.
CAN BUS
This section contains information about the connection of the device to the CAN BUS and the
correct setting of the CAN address.
Connection
The device has two RJ-45 jacks for the CAN BUS. The jacks are connected in parallel, and act
as an input and for daisy chaining the network. The CAN bus allows different data rates to be
used, where the data rate is indirectly proportional to the bus length. If the network is small,
data rates of up to 500 kbit/s are possible. In larger networks, the data rate must be
decreased (down to the minimum data rate of 10 kbit/s), please refer to section Configuring
the CAN baud rate.
Notice!
The data rate is preset to 10 kbit/s in the factory.
The following table explains the relationship between data rates and bus lengths/network
size. Bus lengths of over 1,000 m must be implemented only with CAN repeaters.
