Network Connection Methods

Connect the shield wire of the cable to the FG terminal of the communications power supply
and ground the shield wire.
If more than one power supply is used for communications, ground only the power supply that
is located closest to the middle of the network through the shield wire. Do not ground the
power supply through the shield wire at any other point.
If more than one power supply is connected to the network, connect each of them using a
power supply tap.
