1-4 Setting Environment and Noise Measures
1-4-1 Installation Environment
(1) Do NOT block the air vents of your controller when installing your IA system.
(2) Your controller is NOT dust, water, or oil proof. Take steps to prevent foreign matter from getting into the
controller air vents. 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 place it near a heat source.
(4) Avoid placing your IA system under conditions of extreme tempreratures above 40
o
C or below 0
o
C (32
o
F).
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 IA system.
(6) Take steps to shield all cables and wires from electromagnetic noise.
1-4-2 Power Source
Make certain that 110/120 VAC or 24 VDC (rated 20.4 ~ 26.4VDC) is maintained.
If the power supply tends to fluctuate substantially, use a constant-voltage transformer.
1-4-3 Electromagnetic Noise Supression
(1) Wiring and Power Supply
For grounding, please use a dedicated ground of Class 3 or better. The thickness of the cable should be 2.0~5.5mm
2
or
larger.
