Mechanical Installation - Danfoss VLT DMS 300 Manual

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 2.5-3 Nm.
NOTE
Do not switch on the power 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 organization for further information.
The adjustable frequency drive 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 4 in. (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 adjustable frequency
drive 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 adjustable
frequency drive is to be carried out. See Derating for
ambient temperature. Please note that the service life
of the adjustable frequency drive 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 must not 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 adjustable frequency drive may
not be used to lift the motor/geared motor.
