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.
6.8.1 Converter applications
Converters involve equipment used on a professional basis, deployed in certain areas of
business and industry - and are not operated in the general public domain.
For an EMC-compliant installation, observe the information provided in the Configuration
manual:EMC installation guideline
(http://support.automation.siemens.com/WW/view/en/60612658).
The devices described there are intended for operation in the first and second environments.
Conditions for operation in the respective environment are subsequently listed.
