3. Mounting to the control panel
3.1 Site selection
Caution
• Use within the following temperature and humidity ranges.
Temperature: -10 to 55 (14 to 131 ), Humidity: 35 to 85 %RH (No condensation, no icing)
• When this unit is installed through the control panel, the ambient temperature of this unit – not the
ambient temperature of the control panel – must be kept to under 55 (131 ). Otherwise the life of
electronic components (especially electrolytic capacitors) will be shortened.
This instrument is intended to be used under the following environmental conditions
(IEC61010-1): Overvoltage category , Pollution degree 2
Ensure the mounting location corresponds to the following conditions:
• A minimum of dust, and an absence of corrosive gases
• No flammable, explosive gases
• Few mechanical vibrations or shocks
• No exposure to direct sunlight, an ambient temperature of -10 to 55 (14 to 131 )
that does not change rapidly
• An ambient non-condensing humidity of 35 to 85%RH
• No large capacity electromagnetic switches or cables through which large current flows
• No water, oil or chemicals or where the vapors of these substances can come into direct
contact with the controller
