C.4 Laying and Grounding a Wiring Duct and a Conduit
The following gives an example of laying and grounding a wiring duct and a conduit in FL-net as shown in Fig. C.5
and Fig. C.6.
Wiring must be performed as follows:
• When a wiring duct is used, the power lines and signal lines must be separated with separators according to
their levels. In addition, the wiring duct (including a cover and a separator) must be grounded with a ground
resistance of 100
Ω or less.
• When conduits are used, the conduits should be prepared individually for the power lines and signal lines
according to their levels. In addition, the conduit must be the one defined in JIS-C-8305 and must be grounded
with a ground resistance of 100
Ω or less.
