Notice
When setting the specifications and functions of this controller, connect terminals 2 and 3 for power
source first, then set them referring to Chapter “5. Settings” before performing “3. Mounting to the
control panel” and “4. Wiring”.
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 condensation, no icing)
• When this unit is installed through the control panel, the ambient temperature of this unit must be kept
to under 50
. 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 0 to 50 (32 to 122 )
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
