3. Mounting to the control panel
3.1 Site selection
Caution
Use within the following temperature and humidity ranges.
Temperature: 0 to 50 (32 to 122 ), Humidity: 35 to 85%RH (No icing, non-condensing)
If the BCS1 is installed through the face of a control panel, the ambient temperature of the BCS1 must be
kept to under 50 . Otherwise, the life-span of electronic parts (especially electrolytic capacitors) of the
BCS1 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 0 to 50 (32 to 122 ) 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 where the vapors of these substances can come into direct contact with
the controller
