WARNING
EMC Installation Requirements
Introduction
The EMC European Directive defines electromagnetic compatibility as the
capability of an apparatus, an industrial plant, or a system to work
satisfactorily in the electromagnetic environment, without at the same time
causing electromagnetic disturbances in the apparatus, industrial plant or
systems present in the same environment.
The Electromagnetic Compatibility (EMC) depends on two main
characteristics of the equipment: Electromagnetic Interference (EMI) and
Electromagnetic Susceptibility (EMS). The EMC standards aims to ensure
that all the electrical equipment that could operate simultaneously in the
same environment are compatible. This means that the interference
immunity of all the devices is greater than the interference emission of all
the devices within the same environment.
The EMC requirements for Power Drive System (PDS) are defined in
IEC/EN 61800-3 standard that is included in the Declaration of conformity
CE enclosed. In the European Union, EN61800-3 standard takes priority
over all generic standards. The PDS in the context of this standard
comprises the drive converter, the motor cables and the motor. Therefore,
the installer as the ultimate responsible must follow the installation
instructions given within this manual.
For safety reasons, it is essential to measure the grounding resistance
of the installation. This must be established before the first start up of the
plant and with the drive disconnected.
The installer is responsible of providing the adequate amount, type
and cross section grounding conductor alongside the characteristics
of the drive used and the plant, in order to minimize the grounding
resistance, which must comply with local and national regulations.
