Electromagnetic compatibility

Electromagnetic compatibility
This machine is designed in accordance with IEC/EN 60034, and when used as specified it
satisfies the requirements of European Directive 2014/30/EU on Electromagnetic Compatibility.
2.8

Interference immunity

By selecting suitable signal cables and evaluation units, ensure that the interference immunity
of the machine is not diminished.
2.9
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.
