NOTICE
Damage to the device
If the CAN bus cable's shielding is connected to devices with different po-
tential, current may flow over the shielding. This current may damage the
communication cards.
► Connect the devices to a potential compensation rail to compensate for
potential
► Ensure that the CAN bus cable's shielding is only connected to one de-
vice if both devices have different potentials.
Variant 1: The connected devices share the same potential
If the devices to be connected share the same potential, proceed as follows:
1. Connect all devices to a potential compensation rail to compensate for
the potential.
2. Connect CAN bus cable's shielding to all connected devices.
Variant 2: The connected devices have different potential
Note that the shielding is less effective with this variant.
If the devices to be connected have different potential, proceed as follows:
► Connect CAN bus cable's shielding to just one device.
