The assessment of operating risks and local operating conditions and the necessary
monitoring methods must be clarified and made binding by the system operator in
consultation with the responsible supervisory authority. The required measures must be
adhered to at all times. The machine manufacturer cannot provide any generally applicable
recommendations. Please observe the information in these operating instructions.
Note
The basic requirements relating to the assessment of ignition hazards arising from electrical
equipment and their operation in hazardous
zones are specified in the 2014/34/EU and
1999/92/EC directives as well as in the IEC/EN
60079 series of standards.

Electrostatic sensitive devices
Material damage due to electrostatic discharge
Electronic modules contain components that can be destroyed by electrostatic discharge.
These components can be damaged or destroyed if they are not handled correctly. To
protect equipment against damage, follow the instructions given below.
●Only touch electronic modules if you absolutely have to work on them.
●The body of the person concerned must have been electrostatically discharged and
grounded immediately before any electronic modules are touched.

Risk of explosion due to electrostatic discharge
Electrostatic discharge poses a potential ignition source. Dangerous electrostatic charges
can occur, for example as a result of mechanical friction, flowing air that contains particles -
or persons that are not appropriately grounded, e.g. when carrying out maintenance or
cleaning work.
In an explosive atmosphere, there is a risk of an explosion. This can result in death, serious
injury or material damage.
●Avoid carrying out work specified above on non-metallic parts, e.g. foam rubber for noise
dampeners/attenuators.
●Please comply with ESD protective measures.

2.8
Electromagnetic compatibility
This machine is designed in accordance with IEC/EN 60034, and when used as prescribed it
satisfies the requirements of European Directive 2014/30/EU on Electromagnetic
Compatibility.
2.9
Interference immunity
By selecting suitable signal cables and evaluation units, companies operating complete
plants and systems must ensure that the interference immunity of the machine is not
diminished.
2.10
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.
2.11
Interference voltages when operating the converter
WARNING
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 61000-6-3 for the drive system
(consisting of the machine and converter) from being exceeded.
•You must put appropriate EMC measures in place.
