Electromagnetic compatibility

This machine is designed in accordance with IEC/EN 60034 and, when used as prescribed, it
satisfies the requirements of European Directive 2004/108/EC - from April 20, 2016 of the
European directive 2014/30/EU on Electromagnetic Compatibility.
2.7

Interference immunity

The machine fulfills the requirements regarding interference immunity in conformity with IEC/
EN 61000‑6‑2.
On machines with integrated sensors (e.g. PTC thermistors), the manufacturer of the overall
system must himself ensure sufficient interference immunity by selecting suitable sensor signal
leads and evaluation units.

Influence on the line power supply through a strongly irregular torque

A strongly irregular torque, for example with the drive of a reciprocating motor, forces a non-
sinusoidal motor current. The emerging harmonics can have an impermissible influence on
the line power supply via the connection lines.
