Safety and application notes
for controllers
(according to: Low-Voltage Directive 73/23/EEC)
1. General
During operation, drive controllers may have, according to their type of protection, live,
bare, in some cases also movable or rotating parts as well as hot surfaces.
Unauthorized removal of the required cover, inappropriate use, incorrect installation or
operation, creates the risk of severe personal injury 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 prevention of accidents must be observed).
Qualified skilled personnel according to this basic safety information 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
Drive controllers are components which are designed for installation in electrical systems
or machinery.
When installing in machines, commissioning of the drive controllers (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 89/392/EWG (Machinery Directive); EN 60204 must be
observed.
Commissioning (i.e. starting of operation as directed) is only allowed when there is
compliance with the EMC Directive (89/336/EWG).
The drive controllers meet the requirements of the Low-Voltage Directive 73/23/EWG. 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 to drive
controllers.
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.
Climatic conditions must be observed according to prEN 50178.
Show/Hide Bookmarks

4. Erection
The devices must erected and cooled according to the regulations of the corresponding
documentation.
The drive controllers 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.
Drive controllers contain electrostatically sensitive components which can easily be
damaged by inappropriate handling.Electrical components must not be damaged or
destroyed mechanically (health risks are possible!).
5. Electrical connection
When working on live drive controllers the valid national regulations for the prevention of
accidents (e.g. VBG 4) must be observed.
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.
Notes concerning the installation in compliance with EMC - such as screening, grounding,
arrangement of filters and laying of cables - are included in the documentation of the drive
controllers.These notes must also be observed in all cases for drive controllers with the
CE mark. The compliance with the required limit values demanded by the EMC legislation
is in the responsibility of the manufacturer of the system or machine.
6. Operation
Systems where drive controllers are installed must be equipped, if necessary, 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. Modifications of
the drive controllers by the operating software are allowed.
After disconnecting the drive controllers from the supply voltage, live parts of the
controller 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.
7. Maintenance and servicing
The manufacturer’s documentation must be observed.
This safety information must be preserved!
The product-specific safety and application notes in these operating instructions must
also be observed!
