3 DESIGN

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

(Without Cooling fan unit)

Duct height :

50mm(1.97inch) or less

30mm(1.18inch)

or more

Q173CPU/Q172CPU

(With Cooling fan unit (Shipped from the factory))

50mm(1.97inch)

or more

100mm(3.94inch)

or more

5mm(0.20inch)

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.
