3.3.2 Layout design of the base units
This section describes the precautions related to install a Motion controller in
an enclosure.
(1) To improve ventilation and permit easy replacement of the module, leave a space
of the following table between the top, bottom, side of the module and any other
object.
(For details on layout design refer to section 4.1.2 "Instructions for installation of
the base unit".)
Top Bottom Side
Duct height :
over 50mm(1.97inch)
40mm(1.57inch)
or more

(2) Provide a wiring duct, if required.

CAUTION
Due to ventilation problems, do not install the base units vertically or horizontally.
Install the base units on a flat surface. Unevenness or warping of the surface can apply undue
force to printed circuit boards and lead to operation failures.
Avoid installing the base units close to a vibration source, such as a large electromagnetic
contactor or no-fuse breaker. Install them on a separate panel or at a safe distance.
To limit the effects of reflected noise and heat, leave 100mm(3.94inch) or more clearance to
instruments fitted in front of the Motion controller (on the rear of the door).
Similarly, leave 50mm(1.97inch) or more clearance between instruments and the left and right sides of
the base units.
