Checking and Controlling the Installation Site
The MxC must be installed and used in an area that complies with the conditions listed below. Maintain
the conditions of the area for proper performance life.
Installation Site
Install the MxC under the following conditions, making sure that the area complies with Pollution Level 2 or
less (as defined by UL standards).
The MxC should be installed:
in a clean location free from oil mist and dust.
in an environment where metal shavings, oil, water, or other foreign materials do not get into the MxC.
in a location free from radioactive materials and combustible materials (e.g. wood).
in a location free from harmful gases and liquids.
in a location free from excessive oscillation.
in a location free from chlorides.
in a location away from direct sunlight.
Controlling the Ambient Temperature
To get optimum performance and full product life, the MxC should be installed in an environment free of
extreme temperature changes. If the MxC is installed in an enclosed environment such as a box or enclosure
panel, use a cooling fan or air conditioner to keep the internal air temperature below 45°C.
Protecting the MxC from Foreign Matter
Place a cover over the MxC during installation to shield it from exposure to metal particles when drilling.
Always remove the cover from the MxC after completing installation. Failing to do so will reduce ventilation
and possibly cause the MxC to overheat.

Type Ambient Operating Temperature Humidity
Enclosed wall-mounted -10 to + 40 °C 95% RH or less (no condensation)
