3. Installation and Noise Elimination
Pay due attention to the installation environment of the controller.
3.1 Installation Environment
(1) When installing and wiring the controller, do not block the cooling ventilation holes. (Insufficient ventilation
will not only prevent the controller from demonstrating its full performance, but it may also cause
breakdown.)
(2) Prevent foreign matter from entering the controller through the ventilation holes. Since the enclosure of the
controller is not dustproof or waterproof (oilproof), avoid using the controller in a place subject to significant
dust, oil mist or splashes of cutting fluid.
(3) Do not expose the controller to direct sunlight or radiating heat from a large heat source such as a heat
treatment furnace.
(4) Use the controller in an environment free from corrosive or inflammable gases, under a temperature of 0 to
40
C and humidity of 85% or less (non-condensing).
(5) Use the controller in an environment where it will not receive any external vibration or shock.
(6) Prevent electrical noise from entering the controller or its cables.
3.2 Power Supply
The power supply specification is 24 VDC
 10%.
(Supply current: 2 A max.)
3.3 Noise Elimination and Grounding
This section explains how to eliminate noise in the use of the controller.
(1) Wiring and power supply
[1] Provide a dedicated class D grounding using a wire with a size of 2.0 to 5.5 mm

or larger.
