The operating environmental conditions of the plant are:
Ambient temperature during operation
-15°C to +40°
Ambient humidity during operation
80%
For the installation operations it is necessary to provide a suitable manoeuvring space adapted to the dimensions of the
fan and selected lifting equipment: in the installation zone must be prepared the connection points of the fan to the power
supply network.
WARNING
The building for the installation must be equipped with adequate natural ventilation (no perimeter
walls).
Fig.1
If the fan will be directly assembled to the metal structure of the
building, it is necessary to use bolts M10 A2 screwed in the
appropriate inserts, placed on the stand for the anchorage (two per
side).

•
automatic Climate Control Munters Temp Man, Automatic Speed Regulator Munters or similar (optional).
The characteristics of such devices are shown in the documentation available on http://www.nord.com.
The fan is supplied without any wired command and control circuit; in the assembly phase, the installer must predispose a
control panel which meets the requirements of the standard CEI EN 60439-3 and proceed to the electrical wiring of the fan
in accordance to the indications of the standard CEI EN 60204-1 and IEC 60364.
The electrical panel of the fan must be provided with the following equipment (provided with CE mark according to the
