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
