FCD Series

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.
Stand alone mounting ("wall mounting")
For best cooling the unit should be mounted vertically,
however where space limitations require it, horizontal
mounting is allowable. The integrated 3 wall mounting
brackets in the wall mounting version can be used
for fixing the installation box to the mounting surface,
keeping a distance for possible cleaning between
the box and the mounting surface. Use the three
supplied washers to protect the paint.
Bolts must be M6 for the FCD 303 - 315
and M8 for FCD 322 - 335.
See Dimensional Drawings.
Motor mounting
The installation box should be mounted on the
surface of the motor frame, typically instead of the
motor terminal box. The motor/geared motor may
be mounted with the shaft vertically or horizontally.
The unit mustnot be mounted upside down (the heat
sink pointing down). The cooling of the electronics is
independent on the motor cooling fan. For mounting
directly on Danfoss Bauer geared motors no adaption
plate is necessary. For motor mounting (non Danfoss
Bauer motors), an adaptor plate should usually be
applied. For that purpose a neutral plate incl gasket
and screws for attaching to the installation box is
available. The appropriate drillings and gasket for the
motor housing are applied locally. Please make sure,
that the mechanical strength of the mounting screws
and the threads are sufficient for the application. The
specified resistance against mechanical vibrations
does not cover the mounting onto a non Danfoss
Bauer motor, as the stability of the motor frame
and threads are outside Danfoss Drive
’
s control and
responsibility and the same applies to the enclosure
class. Please be aware, that the frequency converter
may not be used to lift the motor/geared motor.
