Technical data
11.9 Electromagnetic compatibility of the converter
The driven machine is not part of the drive system.
Note
PDS as component of machines or systems
When you install PDS into machines or systems, additional measures may be required so that the
product standards of these machines or systems is complied with. The machine or system
builder is responsible for taking these measures.
Environments and categories
Environments
IEC/EN 61800-3 makes a distinction between the "first environment" and "second
environment" - and defines different requirements for these environments.
• First environment:
Residential buildings or locations at which the PDS is directly connected to a public low-
voltage supply without intermediate transformer.
• Second environment:
All industrial plant/systems or locations that are connected to the public grid through their
own, dedicated transformer.
Categories
IEC/EN 61800-3 makes a distinction between four drive system categories:
• Category C1:
Drive systems for rated voltages < 1000 V for unrestricted use in the "first environment"
• Category C2:
Stationary PDS for rated voltages < 1000 V for operation in the "second environment".
Appropriately qualified personnel are required to install the PDS. An appropriately trained
and qualified person has the necessary experience for installing and commissioning a PDS,
including the associated EMC aspects.
Additional measures are required for operation in the "first environment".
• Category C3:
PDS for rated voltages < 1000 V - only for operation in the "second environment".
• Category C4:
PDS for IT line supplies for operation in complex systems in the "second environment".
An EMC plan is required.
Second environment - category C4
An unfiltered converter corresponds to category C4.
EMC measures in the "second environment", category C4, are implemented on the basis of
an EMC plan at the system level.
