3.1 Site selection
Caution
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 flows
•
No water, oil or chemicals or where the vapors of these substances can come into direct contact
with the controller
•
If the FCL is installed through the control panel, the ambient temperature of the FCL must be kept
to under 50 . Otherwise the life of electronic parts (especially electrolytic capacitors) of the FCL
will be shortened.
Note: Avoid setting this instrument directly on or near flammable material even though the case of
this instrument is made of flame-resistant resin.
