Do not link or connect the ground line
with other devices; ground it for each
controller.
3.1 Installation Environment
Pay due attention to the installation environment of the controller.
(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.
(7) The product can be used in an environment with Pollution Degree 2.
The following explains the noise elimination measures that should be taken when using this controller.
[1] Grounding must be made by ground resistance of 100 7
Moreover, the thickness of cable shall be 1.6 mm or thicker.
