Description

Will customers always receive a copy of technical documentation?
The content of the technical documentation is meant for the
authorities, and thus the electrical equipment manufacturer does
not have to give the technical documentation or any part of it
to the customer.
However, as the customer needs to know whether the product
is in conformance, he will obtain this assurance from the documentation delivered with the product. It is not required to supply
a declaration of conformity with the product, but the end-user
may ask for this from the manufacturer.
What is the shelf life of technical documentation?
Any technical documentation must be accessible to the appropriate authorities for 10 years from the last relevant product
being delivered.
How do I ensure that tests are always carried out?
The whole system is based on self certification and good faith.
In various parts of Europe the methods of ensuring compliance
will vary. Supervision of these regulations is achieved through
market control by a competent authority. If the equipment fails
to meet the requirements of the EMC and Low Voltage Directives
competent authorities can use the safeguard clause of the Directives (withdraw the product from the market, take legal action).
Can drive manufacturers help more?
Manufacturers accept that there is a need to work more closely
with OEMs and machine builders where the converter can be
mounted on the machine. A standard assembly or design should
be achieved so that no new parts of technical documentation
need to be created.
However, the idea of mounting several drives in motor control
centres ( MCCs) must be much more carefully thought out by
system specifiers, as the summing of high frequency emissions
to determine the effects at the MCC terminals is a complex issue
and the possibilities of cross coupling are multiplied.
