(2) A wiring conduit should be provided if required.
If its clearance above or below the programmable controller is less than
indicated in the figure above, observe the following points:
(a) If the wiring conduit is installed above the programmable controller, its
height must be no greater than 50 mm (1.97in.) to ensure good
ventilation.
In addition, there should be adequate space between the
programmable controller and the wiring conduit to allow module latches
to be pressed.
It will not be possible to replace modules if their latches cannot be
pressed.
(b) If the wiring conduit is installed below the programmable controller, it
should be installed so as to allow connection of the optical fiber cable
or coaxial cable, taking the minimum bending radius of the cable into
consideration.
