Without CAN bus surge arresters:
This version only protects against potential differences
up to 1 kV
and cannot be considered to offer lightning protection. In this case, the cable screen must be earthed
at a
single
point between the CAN bus converters, as close to the cable centre as possible. We
recommend earthing the screen
indirectly
in the other buildings using a gas discharge arrester.
Branch cables
As a general principle, branch cables are
not
permitted in a CAN bus network.
The CAN bus converter is used to provide reliable
long
branch cables. This means the branch cable is
disconnected from the other CAN bus network and can be viewed as an independent CAN bus
network.
