Certification B-3
DC590+ Series DC Digital Drive
Provisions have been put in place so that:
• Equipment (apparatus
3
and fixed installations
4
) needs to comply with the requirements of the EMC Directive when it is placed on the market
and/or taken into service.
• The application of good engineering practice is required for fixed installations, with the possibility for the competent authorities of Member
States to impose measures if non-compliances are established.
The directive text makes a clear distinction between the requirements and assessment procedures for apparatus and for fixed installations respectively
(fixed installations can include networks and large machines).
• Fixed installations, although they must comply with the protection requirements, require neither an EC Declaration of Conformity (DoC) nor
CE marking;
• Mobile installations are considered apparatus.
The conformity assessment procedure for apparatus has been simplified to a single procedure. There is no compulsory involvement of a third party, but
the manufacturer has the option of presenting his technical documentation to a Notified Body for assessment.
When deviating from the European harmonized standards or not applying them fully, the manufacturer has to perform an EMC assessment and provide
detailed documentary evidence that the apparatus complies with the protection requirements of the EMC Directive.
Apparatus intended for a given fixed installation and not otherwise commercially available may be exempt from the requirements and procedures for
apparatus (e.g. EC Declaration of Conformity and CE marking), provided that certain documentation requirements are met, including precautions to be
taken in order not to compromise the EMC characteristics of the fixed installation.
BS EN 61800-3 defines the emissions and immunity levels for Power drive systems (PDS) and the main component parts of such a system (Basic drive
module and Complete drive module).
The standard defines specific categories of PDS:
PDS of Category C1
PDS of rated voltage less than 1000V, intended for use in the first environment
PDS of Category C2
PDS of rated voltage less than 1000V, which is neither a plug in device nor a movable device and, when used in the first environment, is
intended to be installed and commissioned only by a professional.
NOTE a professional is a person or organisation having necessary skills in installing and/or commissioning power drive systems,
including their EMC aspects.

‘Apparatus’ means any finished appliance or combination thereof made commercially available as a single functional unit, intended for the end user and
liable to generate electromagnetic disturbance, or the performance of which is liable to be affected by such disturbance.
4
‘Fixed installation’ means a particular combination of several types of apparatus and where applicable other devices, which are assembled, installed and
intended to be used permanently at a predefined location.
