3.3.3 Outdoor Installation
The averaging converter is designed for indoor installation. For outdoor installation, the
averaging converter should be housed in an outdoor case protected from direct sunlight
and the weather. The outdoor case should be equipped with a cooling system for
controlling the internal temperature, if necessary. Also, the outdoor case should be
installed in a location that keeps the case free from corrosive gases or dust.
CAUTION
If an internal temperature rise alarm occurs, use a more effective method to cool the
inside of an outdoor case down to within the converter operating temperature range.
