4 Mounting the Product
4.1 Mounting the Product to the Panel
4.1.1 Panel Cut Size
4.1.2 How to Mount the Unit on the Panel
(1) The recommended panel thickness is 0.8 to 5mm. The tightening torque should be approximately
0.39 to 0.49N･m(4 to 5kgf･ cm). .
(2) Do not install the instrument in locations exposed to direct sunligth, an environment where the
ambient temperature goes beyond the range of 0 to 50℃ or the ambient humidity goes beyond the
range of 35 to 85? , or places where dew condensation is formed due to rapid temperature changes.
(3) Do not install the unit where it is exposed to dust, particles, chemicals harmful to electric components,
corrosive gases, etc.
(4)
Do not install the unit where it is exposed to excessive vibration or shock.
(5)
Install the unit horizontally; otherwise, ventilation will be adversely affected and may result in
deterioration.
(6)
When this unit is installed inside other equipment, pay attention to the heat radiation and keep the
heat inside the equiqment 50℃ or below.
