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 40C 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.: C/CG, 6 A: CF)
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.
