This section describes how to wire the power lines and ground lines for the network equipment in an FL- net system.
When wiring power lines and making ground connections, observe the precautions below.
1.Connect the coaxial cable ground terminal to the class D ground that is specially created for the controller.
2.Connect the frame ground of the hubs for a
3.Provide an exclusive class D or better ground for the controller FG (frame ground) terminal. Do not connect this terminal to the controller frame.
4.Connect the FG (frame ground) terminal of
5.Connect the shield ground on the transceiver (AUI) cable to the FG (frame ground) terminal on the
6.When a transceiver (AUI) needs DC power (12 VDC etc.), provide a stable power supply for exclusive use by the network, and connect the DC output terminals to the
