Safety and application notes
for drive systems
(following Low Voltage Directive 2006/95/EG)
1. General
During operation, filter modules may have, according to their
type of protection, live, bare, in some cases also movable or
rotating parts as well as hot surfaces.
Non –authorized removal of required cover, inappropriate use,
incorrect installation or operation, creates the risk of severe
injury to persons or damage to material assets.
Further information can be obtained from the documentation.
All operations concerning transport, installation and
commissioning as well as maintenance must be carried out by
qualified, skilled personnel (IEC 364 and CENELEC HD 384 or DIN
VDE 0100 and IEC-Report 664 or DIN VDE 0110 and national
regulations for the preventions of accidents must be observed).
According to this basic safety information qualified skilled
personnel are persons who are familiar with the erection,
assembly, commissioning and operation of the product and who
have the qualifications necessary for their occupation .
2. Application as directed
Filter modules are components which are designed for
installation in electrical systems or machinery.
When installing in machines, commissioning of the filter module
(i.e. the starting of operation as directed) is prohibited until it is
proven, that the machine corresponds to the regulations of the
EC Directive (2006/42/EG) (Machinery Directive); EN 60204 must
be observed.
Commissioning (i.e. starting operation as directed) is only
allowed when there is compliance with the EMC-Directive
(2004/108/EG).
The filter modules meet the requirements of the Low-Voltage
Directive (2006/95/EEC). The harmonized standards of the prEN
50178/DIN VDE 0160 series together with EN 60439-1/DIN VDE
0660 part 500 and EN 60146/DIN VDE 0558 are applicable for the
power feedback unit. The technical data and information on the
connection conditions must be obtained from the nameplate and
the documentation and must be observed in all cases.
3. Transport,storage
Notes on transport, storage and appropriate handling must be
observed. At non-observance any warranty expires.
The filter module unit has to be protected from inadmissible
stress. The transport is only valid in original packaging and in the
thereon by pictograms marked transport position.
In particular during transport and handling no components are
allowed to be bent and / or isolating distances may not be
altered. The modules are equipped with electrostatic sensitive
devices, which may be damaged by improper handling.
Therefore it has to be avoided to get in contact with electronic
components. If electronic components are damaged
mechanically the module must not be put into operation, as it
cannot be ensured, that all relevant standards
This safety information must be kept!
4. Erection
The modules must be erected and cooled according to the
regulations of the corresponding documentation.
The filter modules must be protected from inappropriate loads.
Particularly during transport and handling, components must
not be bent and / or isolating distances must not be changed.
Touching of electronic components and contacts must be
avoided.
Filter modules contain electro-statically sensitive components
which can easily be damaged by inappropriate handling.
Electrical components must not be damaged or destroyed
mechanically (health risk are possible!).
5. Electrical Connection
When working on live filter modules, the valid national
regulations for the prevention of accidents (e.g. VBG 4) must be
observed. Before any installation or connection works, the plant
has to be switched off and to be secured properly.
The electrical installation must be carried out according to the
appropriate regulations (e.g. cable cross-sections, fuses, PE-
connection). More detailed information is included in the
documentation. When using the filter module with controllers
without safe separation from the supply line (to VDE 0100) all
control wiring has to be include in further protective measures
(e.g. double insulated or shielded, grounded and insulated) .
Notes concerning the installation in compliance with EMC –such
as screening, grounding, arrangement of filters and laying of
cables –are included in the chapter installation of this
documentation. These notes must be also observed in all cases
for filter modules with the CE-mark. The compliance with the
required limit values demanded by the EMC legislation is the
responsibility of the manufacturer of the system or machine.
6. Operation
Systems where filter modules are installed, if applicable, have
to be equipped with additional monitoring and protective
devices according to the valid safety regulations e.g. law on
technical tools, regulations for the prevention of accidents,
etc.. After disconnecting the filter module the supply voltage,
live parts of the filter module and power connections must not
be touched immediately, because of possibly charged
capacitors. For this, observe the corresponding labels on the
drive controllers.
During operation, all covers and doors must be closed
