The power line connected to the power or
servo amplifier and the communication
cable are mixed in the duct.
Wiring the power line and communication
cable in the panel without mixing them in
the duct can reduce the influence of noise.
The power line and communication cable
are installed together.
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.
