Figure 8-76 Typical FL-net System Power Supply Wiring and Grounding
8.7.3 Power supply wiring and grounding for FL-net system network devices
Figure 8-77 shows a typical power supply wiring/grounding scheme for the network devices of the
FL-net system.
When making power supply wiring and ground connections, observe the following instructions:
• Connect the ground terminal on a coaxial cable to the Class D ground that is dedicated to the
controller.
• Connect the frame ground of the 10BASE-T hub to the Class D ground that is dedicated to the
controller. Also, ensure that the 10BASE-T hub receives power from the same insulating
transformer with a static shield as for the controller power supply.
• Do not connect the controller’s FG (frame ground) terminal to the frame of the control panel.
Provide the controller with dedicated Class D or higher grounding.
• Connect the FG (frame ground) terminal on the FL.NET module to the FG (frame ground)
terminal on the controller.
• Connect the shield ground of the transceiver (AUI) cable to the FG (frame ground) terminal on the
FL.NET module.
