FCM Series
3. The FC motor is sold as part of a complete system.
The system is being marketed as complete. It could
be e.g. an air-conditioning system. The complete
system must be CE labelled in accordance with
the EMC directive. The manufacturer who supplies
the system can ensure CE labelling under the EMC
directive either by using CE labelled components or
by testing the EMC of the system. If he chooses
to use only CE labelled components, he does
not have to test the entire system.

Danfoss FCM 300 Series motor and CE labelling
CE labelling is a positive feature when used for its original
purpose, i.e. to facilitate trade within the EU and EFTA.
However, CE labelling may cover many different
specifications. This means that it has to be checked
what a given CE label specifically covers.
The specifications covered can in fact be widely
different. That is why a CE label can give the installer
a false feeling of security when using a FC motor as
a component in a system or an appliance.
We CE label our VLT
®
DriveMotors in accordance with
the low-voltage directive. This means that as long as
the FC motor is installed correctly, we guarantee that
it complies with the low-voltage directive. We issue a
declaration of conformity that confirms our CE labelling
in accordance with the low-voltage directive.
The CE label also applies to the EMC directive,
on condition that the instructions given in the
Operating Instructions for EMC-correct installation
and filtering have been followed. On this basis,
a declaration of conformity in accordance with
the EMC directive is issued.
The Quick Guide gives detailed instructions for
installation to ensure that your installation is
EMCcorrect. Furthermore, we specify which norms
that are complied with by our different products.
We offer the filters that can be seen from
the specifications and gladly provide other types of
assistance that can help you obtain the best EMC result.

Compliance with EMC directive 89/336/EEC
In the great majority of cases, the VLT DriveMotor
is used by professionals of the trade as a complex
component forming part of a larger appliance,
system or installation. It must be noted that the
responsibility for the final EMC properties of the
appliance, system or installation rests with the installer.
As an aid to the installer, Danfoss has prepared EMC
installation guidelines for the Power Drive System.
The standards and test levels stated for Power
Drive Systems are complied with, provided the right
EMC-correct instructions for installation have been
followed, see electrical installation.
