Classification Of Emc Behavior - Siemens SINAMICS S120 Manual

Compliance with the EMC Directive of the EC is ensured by taking the measures described
in the Configuration Manual "EMC Installation Guideline" (article number 6FC5297-0AD30-
0.P.).
For installation of components in cabinets, the following conditions must additionally be
fulfilled for compliance with the EMC Directive:
● Operation on TN and TT line supply systems with grounded neutral point
● Observance of information about cable shielding and equipotential bonding
● Use of the recommended power and signal cables from Siemens.
● Only use Siemens cables for the DRIVE-CLiQ connections.
Note
EMC requirements for Safety Integrated
In order to meet the requirements for interference immunity of IEC 61800-5-2 (2nd Ed.,
2016), Annex E, the drive systems are permitted to be operated only after installation in a
control cabinet.
6.3.2

Classification of EMC behavior

The EMC environments and EMC categories are defined in the EMC product standard
IEC 61800-3 as follows:
Environments
First environment (public systems)
An environment that includes domestic premises and establishments that are connected
directly to a public low-voltage line supply without the use of an intermediate transformer.
Examples: houses, apartments, commercial premises or offices in residential buildings.
Second environment (industrial systems)
An environment that includes all other establishments that are not connected directly to a
public low-voltage line supply.
Examples: industrial and technical areas of buildings fed from a dedicated transformer.
Categories
Category C1
Drive systems with a rated voltage < 1000 V that are intended for unrestricted use in the first
environment.
Category C2
Stationary drive systems with a rated voltage < 1000 V for operation in the second
environment.
