2.6 Electromagnetic compatibility
Electromagnetic compatibility
This machine is designed in accordance with IEC/EN 60034, and when used as specified, it
complies with the requirements of European Directive 2014/30/EU regarding Electromagnetic
Compatibility.
2.7 Interference immunity
By selecting suitable signal cables and evaluation units, ensure that the interference
immunity of the machine is not diminished.
2.8 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.
2.9 Interference voltages when operating the converter
Interference voltages when operating the converter
When a converter is in operation, the emitted interference varies in strength depending on
the converter (manufacturer, type, interference suppression measures undertaken). On
machines with integrated sensors (e.g. PTC thermistors), interference voltages caused by the
converter may occur on the sensor lead. This can cause faults which can result in eventual or
immediate death, serious injury or material damage.
•Comply with the EMC information provided by the manufacturer of the converter. This is
how you prevent the limit values stipulated by IEC/EN 61000-6-2 .... IEC/EN 61000-6-4 for
the drive system (consisting of the machine and converter) from being exceeded.
•You must put appropriate EMC measures in place.
2.10 Special designs and construction versions
Before carry out any work on the machine, determine the machine version.
If there are any deviations or uncertainty, contact the manufacturer, specifying the type
designation and serial number (see the rating plate), or contact the Service Center
(Page 123).

3.1 Area of application
The rotating electrical motors of this series are used as industrial drives. They are designed for
a wide range of drive applications both for line operation as well as in conjunction with
frequency converters.
They are characterized by their high power density, extreme robustness, long service life and
outstanding reliability.
Correct and intended use of the machines
These machines are intended for industrial installations. They comply with the harmonized
standards of the series EN / IEC 60034 (VDE 0530). It is prohibited to use these motors in
hazardous zones if the marking on the motor rating plate does not explicitly permit line or
converter operation. If other/more wide-ranging demands (e.g. protection so that they
cannot be touched by children) are made in special cases – i.e. use in non-industrial
installations – these conditions must be ensured by the customer.
