Unit: mm (inch)
(2) Unit mounting position
To ensure proper ventilation and make module replacement easy, provide
a clearance of 80 mm (3.15 in.) or more between the top of the unit and
any surrounding structure or equipment.

Parallel installation
Represents the ceiling of panel,
wiring conduit, or component.
(3) 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 (1.97 in.) 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.
