Safety and application notes for controllers
EíçW içïJsçäí~ÖÉ aáêÉÅíáîÉ TPLOPLbb`F
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.
Non-authorized removal of the 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 prevention 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
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/EEC (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/EEC).
The drive controllers meet the requirements of the Low Voltage
Directive 73/23/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 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.
4. Erection
The devices must be 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 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 kept!
The product-specific safety and application notes in these
Operating Instructions must also be observed!
