C.3 Network Equipment Connection in the FL-net System
The following shows an example of installing network equipment (transceivers, hubs, etc.) in the FL-net system as
shown in Fig. C.4.
• Note that the transceiver should be installed in a metal installation box with a wooden insulation cover. The
installation box must be grounded with a ground resistance of 100 Ω or less.
• A transceiver cable must be wired to the control panel of the controller by means of a conduit. The conduit
must also be grounded with a ground resistance of 100 Ω or less.
• The hub must be installed within the control panel of the controller with a U-shaped fitting. The hub must be
electrically insulated from the fitting by rubber feet. The fitting must be grounded to the control panel of the
controller, and the control panel must be grounded with a ground resistance of 100
Ω or less.
