6.4.3 Connecting cables to the system periphery
To obtain a better overview when connecting cables, only use as many
leads as necessary.
To connect cables to the system periphery, proceed as follows:
ü
Use only the specified cables for wiring. Note the cable recommendation.
► Connect the lines to be wired to the device to the system periphery as
shown in the connection diagrams supplied.
6.4.4 Connecting the CAN bus
6.4.4.1 Shielding the CAN bus
In order for the CAN bus to operate faultlessly, you have to connect the
shielding using one of the following variants. If you are not able to use any of
the variants detailed below, we recommend using fiber-optic cables. Fiber-
optic cables decouple the devices and are not sensitive to electromagnetic
interference (surge and burst).
NOTICE
Damage to the device!
If you connect the CAN bus cable to devices with different potentials, cur-
rent may flow across the shielding. This current may damage the device.
► Connect the devices to a potential equalization rail to equalize the poten-
tial.
► If both devices have different potentials, only connect the CAN bus cable
shielding to one device.
