[5] Wiring and grounding through wiring ducts and conduits

Shown below are methods for wiring and grounding through wiring ducts and conduits used on an FL- net.

Observe the precautions below when wiring

1.When wiring using wiring ducts, separate the power lines and signal lines using a physical separator. The wiring duct itself (including the lid and separator) must be grounded with a class D ground.

2.When using conduits, provide one conduit for the power lines and one for the signal lines. Use conduit that complies with JIS-C-8305 and create a class D ground.
