Safety Precautions
(1) Do not apply a voltage or current exceeding the maximum allowable
value; otherwise, it may damage the equipment.
(2) Use a power voltage within the operation range; otherwise, it may result
in a fire, electrical shock, or malfunction.
(3) The contents of this manual are subject to change without notice.
(4) Although the contents of this manual have been prepared with extra
care, if you have any questions, or find errors or missing information,
contact the sales agent from which you purchased the product or
.
After reading this manual thoroughly, keep it in a convenient place for
future reference.

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.
