AKD-C/N Safety Notes | 3 Approvals
3.2 Conformance with EC Low Voltage and EMC Directives
EU Declarations of Conformity can be found on the
Conformance with the EC EMC Directive 2014/30/EU and the Low Voltage Directive
2014/35/EU is mandatory for the supply of drives within the European Community.
The devices have been tested by an authorized testing laboratory in a defined configuration,
using the system components that are described in this documentation. Any divergence from
the configuration and installation described in this documentation means that the user will be
responsible for carrying out new measurements to ensure conformance with regulatory
requirements.
Kollmorgen declares the conformity of the product series AKD-C/N with the following dir-
ectives:
EC Directive 2006/42/EU, Machinery Directive
Used harmonized standard EN13849-1 (2008)
EC Directive 2014/35/EU, Low Voltage Directive
Used harmonized standard EN61800-5-1 (2007)
EC Directive 2014/30/EU, EMC Directive
Used harmonized standard EN 61800-3 (2004)
The AKD-C/N meet the noise immunity requirements to the 2nd environmental category
(industrial environment). For noise emission the AKD-C/N meet the requirement to a product
of the Category C2.
These devices can cause high-frequency interferences in non industrial environments and
may require measures for interference suppression (such as additional external EMC fil-
ters).
3.3 Conformance with EC Machinery Directive, Functional Safety
Conformance with the EC Machinery Directive 2006/42/EU is mandatory for the supply of
safety components within the European Community. The STO safety implementation on the
AKD is certified by TÜV. The safety circuit implementation used for the safety function "Safe
Torque Off" in the drives is suited for SIL 2 according to IEC 62061 and PLd / CAT3 accord-
ing to ISO 13849-1.
