Classification Of Emc Behavior - Siemens SINAMICS S120 Manual

Conformance with the EMC Directive of the EC is ensured by following the measures
described in the Configuration Manual, "EMC installation guideline".
When installing components in cabinets, in order to fulfill the EMC Directive, the following
conditions must be additionally observed:
● Operation on TN and TT line supply systems with grounded neutral point or grounded
protective conductor as well as on IT line supply systems
● Observance of information about cable shielding and equipotential bonding
● Use of the recommended power and signal cables from Siemens.
● Only use cables from Siemens for the DRIVE-CLiQ connections (see Chapter DRIVE-
CLiQ signal cables (Page 704))

Classification of EMC behavior

The EMC environments and categories are defined in the EMC Product Standard
EN 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, which are intended for unrestricted use in the
first environment.
Category C2
Stationary drive systems with rated voltages < 1000 V for operation in the second
environment.
Drive systems, Category C2 may only be used in the first environment when they are
installed and commissioned by appropriately trained professionals, and the limit values for
harmonic currents are complied with.
