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

10.6

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.
Precondition
1. The laws for protection from electromagnetic fields in force in individual EU member states
can go beyond the minimum requirements of the EMF Directive 2013/35/EU and always
take precedence.
2. The ICNIRP 2010 limits for the workplace are the basis for the assessment.
3. The 26th BImSchV (German Federal Emission Protection Regulation) defines 100 μT (RMS)
for the assessment of active implants. According to Directive 2013/35/EU, 500 μT (RMS) at
50 Hz is applicable here.
4. Compliance with the limit values was assessed for the following frequencies:
– Line frequency 47 Hz to 63 Hz
– Pulse frequency, for example 4/8/16 kHz and multiples thereof, assessed up to a
5. The routing of power cables has a significant impact on the electromagnetic fields that
occur. Install and operate the components inside metallic cabinets in compliance with the
documentation and use shielded motor cables.
Description
The following information regarding electromagnetic fields relates solely to converters
supplied by Siemens.
The converters are normally used in machines. The assessment and testing is based on DIN
EN 12198.
The indicated minimum distances apply to the head and complete torso of the human body.
Shorter distances are possible for extremities.
