1-5 Setting Environment and Noise Measures
Please be careful for controller setting environment
1-5-1 Installation
Environment
This controller can be used in an environment of pollution degree 2
*1
or equivalent.
*1 Pollution degree 2: Normally only nonconductive pollution occurs. Temporary conductivity caused by
condensation is to be expected.
(EN60947-5-1)
(1) Do NOT block the air vents of your controller when installing your IA system.
(Unavailability of sufficient ventilation not only prevents the controller from demonstrating its designed
performance, but it may also lead to a controller failure.)
(2) Prevent foreign matters from entering the controller through the vent holes. Your controller is NOT dust,
water, or oil proof. Avoid using your IA system in environments subject to contamination by dust, oil, mist, or
cutting oil.
(3) Do not expose your IA system to direct sunlight or radiation heat from a large heat source such as heat treat
furnace, etc.
(4) Avoid placing your IA system under conditions of extreme temperatures above 40
C or below 0C. The level
of humidity should not be exceed 85%. Do NOT expose to corrosive or inflammable gas.
(5) Avoid external vibration, unnecessary impact, or excessive shocks to your controller.
(6) Take steps to shield controllers and wiring cables from electromagnetic noise.
1-5-2 Power
Source
There are AC 100 V and AC 200 V depending on the controller specification.
1-5-3 Noise Elimination Measures and Grounding
(1) Wiring and Power Supply
The PE terminal on the power-supply terminal block is used for safety grounding. Provide a class D grounding
connection to this terminal.
The thickness of the cable should be 0.75 mm
2
(#18AWG) or larger and above AC cables.
