Electromagnetic Compatibility (Emc); Ul Approval For The Us And Canada - Beckhoff AX8000 Series Manual

Guidelines and Standards
2.2

Electromagnetic compatibility (EMC)

Beckhoff Automation GmbH & Co. KG guarantees the conformity of the AX8000 multi-axis servo system to
the EMC Directive 2014/30/EU.
Applied harmonized standards:
• IEC / EN 61800-5-3
Installation of electrical systems and components
In order to be able to establish an effective protective earth conductor system, in addition to the protective
conductors and all electronic components all conductive components of a machine must be included in the
protective earth conductor system through equipotential bonding.
Attachment of the protective earth conductor!
When installing electrical systems and components, the protective earth conductors should
always be connected first and removed last. The specifications for the protective earth con-
ductor connections depend on the level of leakage currents:
• The minimum requirement for the protective earth conductor is a KU value
• The minimum requirement for leakage currents is I
1)
The KU value is a variable for the classification of safety-related types of failure for protection against
dangerous shock current and excessive heating. A value of KU = 4.5 in relation to interruption is attained:
• with a permanently attached protective earth conductor ≥ 1.5 mm²
• for protective earth conductor connections ≥ 2.5 mm² with connectors for industrial systems (IEC
60309-2).
KU = 6 in relation to interruption is attained with permanently connected conductors ≥ 10 mm², wherein the
type of connection and routing must comply with the standards applicable to PE conductors.

UL approval for the US and Canada

The German translation of this chapter is purely informative!
All statements made in the English version (AX8000 – System Manual Version 1.0) of this
chapter are binding!
The following components of the AX8000 multi-axis servo system are cULus-certified (E-number E195162):
Modules from the AX8000 series with UL certification
AX8620, AX8640, AX8108, AX8118, AX8206, AX8810
The above components are permitted to bear the certification logo on the type plate. If you wish to operate a
servo drive from the AX8000 series in the USA or Canadian economic areas, please check whether the
cULus sign appears on the type plate.
Below is a list of the relevant chapters that are amended with respect to the cULus approval. Furthermore,
UL-specific remarks are listed.
