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 gas-
ket 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.
1.
Prepare the adaptor plate for mounting on the motor by drilling
the fixing holes and the hole for the cables.
2.
Mount the plate on the motor with the normal terminal box gas-
ket.
3.
Knock out the 4 screw holes for mounting the adaptor plate
(outer holes).
4.
Mount the terminal box onto the motor by the 4 sealing screws
and the gasket supplied.
Use the supplied star washers for securing PE connection ac-
cording to EN 60204. The screws must be tightened with 5 Nm.
