Choosing the best installation location
p This unit is designed for indoor use only.
p Install the unit on a sufficiently strong, stable and level
surface for use.

In particular, ensure sufficient space between ventilation
and wiring when using mounted in a panel or table.
p Do not install the unit in a cold place where the
temperatures will drop below 0 °C (32 °F) or in a hot
place where the temperatures will rise above 40 °C
(104 °F).
p Avoid installing the unit where it will be exposed to direct
sunlight or to the hot air that is blown out from other
products.
p Installing the unit in a very humid, dusty or vibration-
prone location may give rise to trouble.
