1 SAFETY AND APPLICATION NOTES FOR DRIVE CONVERTERS
(According to the 72/73/EC Low-voltage Guideline)
10.25.96/HX/PT/BLY
1. General
Depending on their protection class, drive converters may have
non-isolated and live conductors, possibly moving or rotating
parts, and hot surfaces.
There is danger of severe personnel or equipment damage if the
required cover is inadmissibly removed, the unit is used in an
inadmissible application, improperly installed or operated.
Refer to the documentation for further information.
All work concerning transportation, installation, and
commissioning as well as maintenance is to be performed by
qualified expert personnel (take also note of the IEC 364 and/or
DIN VDE 0100 and national accident prevention regulations).
Expert personnel for electrical devices
Personnel, which is based on his/her professional training,
experience and knowledge of the applicable standards and
capable to judge the tasks to be performed and to recognize
possible sources of danger.
Personnel trained for electro-technical operation
Personnel informed by the expert personnel for electrical
devices regarding the tasks assigned to him/her and the
possible danger occurring at improper acting’s and who is
trained if required and instructed about the required safety
mechanisms and protective measures.
2. Intended use
Drive converters are components supposed to be included into
electrical equipment or machines.
When installing the drive converter into a machine, its
commissioning (i.e. taking up its intended operation) is
prohibited until it is ascertained that the machine conforms to the
regulations described by the EC guideline 93/44/EC (Machine
Guideline). Take note of EN 60204.
Commissioning (i.e. taking up its intended operation) is only
allowed if the Electromagnetic Compatibility guideline
(89/336/EC) is observed.
The drive converters fulfil the requirements of the 73/23/EC
Low-voltage Guideline. Drive converters are subject to the
harmonized standards of the prEN 50178/DIN VDE 0160 in
association with EN 60439-1/VDE 0660 part 500 and EN
60146/VDE 0558.
The specifications and the data concerning the connection
conditions are stated on the rating plate and in the
documentation of the component. Meeting these data and
conditions is compulsory.
3. Transport and storage
The notes regarding transport, storage and appropriate
operation must be observed.
Climatic conditions must be complied with as detailed by prEN
50178.
4. Setting up
Setting up and cooling of the devices must be made according
to the rules described in the corresponding documentation.
Drive converters are to be protected against inadmissible
stress. Particularly, no components may be twisted and/or no
isolation distances may be changed. Touching of electrical
components and contacts is to be prevented.
Drive converters include components, which can be damaged
by electrostatic discharge. When handled improperly, these
components can be easily damaged. Electrical components
may not be damaged or destroyed by using mechanical force
(this may endanger health).
5. Electrical connection
The valid national accident prevention regulations (e. g. VGB4)
must be observed when working on drive converts which are
connected to the supply voltage.
The electrical set-up has to be performed according to the
relevant regulations (e.g. conductor diameter, fusing,
protective conductor connection). Furthermore, the
documentation contains notes concerning this subject.
Notes relevant to a proper EMC-conforming set-up (e. g.
screening, earthing, arrangement of filters, and cable routing)
are to be found in the documentation of the drive converters.
These notes must always be observed even when working
with drive converters with the CE mark. The manufacturer of
the plant or of the machine is responsible for the observance
of the required limit values as defined by the EMC regulations.
6. Operation
If applicable, plants fitted with drive converts must be equipped
with additional monitoring and safety devices according to the
currently valid safety regulations, e. g. law concerning work
equipment, accident prevention regulations, etc. Modifications
of the drive converters using the operating software are
admissible.
Touching of equipment parts that are subject to voltage in
operating conditions and of wire connections is not allowed
directly after disconnecting the supply voltage. There is the
danger of still charged capacitors! Fore this, all relevant safety
markings on the drive converter must be observed.
During operation, covers and doors must be kept shut.
7. Maintenance
The manufacturer’s documentation must be observed.
These safety notes must be kept in a safe place!
