1.3.1 Recommendations with respect to
EMC
In order to fulfil the European EMC Directive 2004/108/
EC regarding electromagnetic compatibility, the following
precautions must be taken:
• The motor cable must be mounted as close to the heat
exchanger housing as possible. If the cable is too long,
the excess should be collected together in the form of, for
example, a figure “8”. The area enclosed by the cable
should be as small as possible. Electrical tape or cable ties
can be used to achieve this.
Fig. 1 Excess motor cable should be arranged such that the
area enclosed is as small as possible
Special EMC couplings/glands are necessary. An EMC filter
is built into all EMX-D units,
