2.1 Installation
Requests/Precautions
In order to enhance the reliability of RCON and to fully utilize its functions, consider the following
before installation.
[Installation Environment]
Usage is possible in environments of pollution degree 2
*1
or equivalent.
*1 Pollution degree 2: Environment in which generally only nonconductive pollution occurs, but
temporary conductive pollution may occur due to condensation. (IEC60664-1)
Avoid the following locations for installation.
• Where the ambient temperature exceeds the range of 0 to 55°C
(If there is no fan unit, derating is available.)
For simple absolute units and SCON, where the ambient temperature exceeds the range of 0 to 40
°C
• Where the temperature changes rapidly and condensation occurs
• Where the relative humidity exceeds 85% RH
• Where the unit is exposed to odorous or combustible gases
• Where the unit is exposed to significant amounts of dust, salt or iron powder
• Where the unit is subject to direct vibration or impact
• Where the unit receives direct sunlight
• Where the unit may come in contact with water, oil or chemical spray
• Where vents are blocked [see the section for installation and noise countermeasures]
If the unit is used in any of the following locations, provide sufficient shielding measures:
• Where noise is generated due to static electricity, etc.
• Where there are strong electrical or magnetic fields
• Where mains or power lines pass nearby
