Installation Precautions

CautionThis instrument is intended to be used under the following environmental conditions (EN61010-1):• 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• No mechanical vibrations or shocks• No exposure to direct sunlight, an ambient temperature of -10 to 50°C (14°F to 122°F ) that does
not change rapidly, and no icing• An ambient non-condensing humidity of 35 to 85 %RH• No large capacity electromagnetic switches or cables through which large current is flowing• No water, oil or chemicals or the vapors of these substances can come into direct contact with theunit.
• When installing this unit within a control panel, please note that ambient temperature of this unit –not the ambient temperature of the control panel – must not exceed 50°C (122°F).
Otherwise the life of electronic components (especially electrolytic capacitor) may be shortened.
* Avoid setting this instrument directly on or near flammable material even though the case of this
