Leading the power line and
communication cable outside the
panel at separate places can
make the communication cable
less influenced by noise from the
power line. Installing the
communication cable apart from
the power line or using a
separator (made of metal) in the
duct as shown in Fig. B can make
the communication cable less
influenced by noise.
