Protecting Persons From Electromagnetic Fields - Siemens SINAMICS G115D Operating Instructions Manual

Technical data
11.5 Protecting persons from electromagnetic fields
• Shielded motor cable with low capacitance
• Shielded external braking resistor cable with low capacitance
• Pulse frequency ≤ factory setting
• Converters with integrated C2 line filter
Note
The SINAMICS G115D converter is designed for operation in the second environment (industrial
area) and may not be used in the first environment (residential area) unless the appropriate
noise suppression measures have been adopted.
Note
A power drive system consisting of multiple units connected together in daisy-chain may require
further measures to meet EMC requirements.

Protecting persons from electromagnetic fields

Overview
Protection of workers from electromagnetic fields is specified in the European EMF Directive
2013/35/EU. This directive is implemented in national law in the European Economic Area (EEA).
Employers are obligated to design workplaces in such a way that workers are protected from
impermissibly strong electromagnetic fields.
To this end, assessments and/or measurements must be performed for workplaces.
