EMC Installation Requirements
Introduction
The European EMC Directive defines electromagnetic compatibility as follows: 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 disturbance, which would be unacceptable to
apparatus, industrial plant, or systems present in this environment.
The Electromagnetic compatibility (EMC) depends on two mains characteristics of the equipment: the
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. That means 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 European Union, EN61800-3 standard takes
precedence over all generic or previously applicable product family EMC 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.
Depending on the location of the drive, the standards define four categories distributed in two
environments.
•
First Environment: First Environment includes domestic premises. It also includes
establishments directly connected without an intermediate transformer to a low-voltage power
supply network, which supplies buildings used for domestic purposes such as shopping malls,
cinemas, hospitals…
•
Second environment : Industrial use. Second Environment includes all establishments other
than those directly connected to a low-voltage power supply network, which supplies buildings
used for domestic purposes. E.g. factories and those other premises supplied by their own
dedicated transformer.
