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
) (No icing), Humidity: 35 to 85%RH (Non-condensing)
If the WCL-13A is installed within a control panel, the ambient temperature of the unit - not the ambient
temperature of the control panel - must be kept to under 50
. Otherwise the life of electronic parts
(especially electrolytic capacitors) of the unit 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
• No 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 is flowing
• No water, oil or chemicals or where the vapors of these substances can come into direct contact with the unit

Notice
When setting the specifications and functions of this controller, connect terminals 13 and 14 for power
supply first, then set them referring from “6. Outline of Key Operation and Setting Groups” to “8. Setup”
before performing “3. Mounting to the Control Panel” and “5. Wiring”.
