3.1.3 Spacing for Mechanical Installation
All units require a minimum of 100 mm air from other components above
and below the enclosure.
3.2 Mechanical Installation
Please pay attention to the requirements that apply to integration and remote mounting. These must be complied with to avoid serious
injury or damage, especially when installing large units.
The FCD 300 consists of two parts: The installation part and the electronics part.
The two parts must be separated, and the installation part is to be mounted first. After wiring, the electronics is to be fixed to the installation part by the
attached 6 screws. For compressing the gasket the screws must be tightened with 2-2.4 Nm, tighten both centre screws first, thereafter the 4 corner
srews “cross over”.
NB!
Do not switch on the mains before the 6 screws are tightened.
The FCD 300 can be applied as following:
-
Stand alone mounted close to the motor
-
Motor mounted
or might be delivered pre mounted on a Danfoss Bauer (geared) motor. Please contact the Danfoss Bauer sales organisation for further information.
The frequency converter is cooled by means of air circulation. For the unit to be able to release its cooling air, the minimum free distance above and
below the unit must be
minimum 100 mm
. To protect the unit from overheating, it must be ensured that the ambient temperature does not rise above
the max. temperature stated for the frequency converter and that the 24-hour average temperature is not exceeded. The max. temperature and 24-hour
average can be seen in
General Technical Data
. If the ambient temperature is higher, derating of the frequency converter is to be carried out. See
Derating for Ambient Temperature
. Please note that the service life of the frequency converter will be reduced if derating for ambient temperature is not
considered.
