● When commissioning the system, with reference to the rated voltage UN of the winding
insulation, carefully ensure that no converter-related overvoltages with a peak value
exceeding (1.1 · √2 · UN) occur at the terminals of the electric motor.
● If the motor is equipped with anti-condensation heating, using an interlock circuit, ensure
that the anti-condensation heating can only be operated when the motor is shut down.

● Once the motor has been shut down, the anti-condensation heating may only be switched
on after a specified wait time has elapsed. The information provided in the Operating
Instructions must be strictly complied with.
● If the motor is equipped with a separately driven fan, using an interlock circuit, ensure that
the motor can only be operated when the separately drive fan is switched on.
2.6 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.
● Electronic modules should not be brought into contact with electrically insulating materials,
such as:
– Plastic film
– Plastic parts
– Insulating table supports
– Clothing made of synthetic fibers
● Always place electrostatic sensitive devices on conductive bases.
● Always pack, store and transport electronic modules or components in conductive
packaging, such as:
– Metallized plastic or metal containers
– Conductive foam material
– Domestic aluminum foil

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.
2.7 Processes that generate high levels of electrostatic charge
Processes that generate high levels of electrostatic charge
Processes that generate high levels of electrostatic charge, which are far higher than those
generated through manual rubbing, include the following:
● Operation of high-voltage electrodes and ionizers
● Presence of high-speed particles on surfaces, e.g. sprayed charges (electron and ion flows)
in electrostatic coating processes
● Pneumatically conveyed dusts and bulk goods
● Flowing or hydraulically conveyed liquids and drops
● Belts, brushes and foils etc. moved by machines

Risk of explosion as a result of processes with high levels of electrostatic charging
Processes with high levels of electrostatic charging can result in propagating brush discharge/
brushing discharge and explosion
This can result in death, serious injury or material damage.
● Avoid all of these processes in areas where there is risk of gas and dust explosions at non-
metallic exposed components, e.g. paint finishes. These discharge types are not addressed
in current standards.
● The non-metallic exposed components, e.g. paint finishes are subject to an electrostatic
suitability test. When supplied, the motor has its original paint finish.
2.8 Electromagnetic fields when operating electrical power engineering
installations
Electrical power equipment generate electromagnetic fields during operation. Potentially lethal
malfunctions can occur in medical implants, e.g. pacemakers, in the vicinity of electrical power
equipment. Data may be lost on magnetic or electronic data carriers.
● Protect the personnel working in the plant by taking appropriate measures, such as erecting
identifying markings, safety barriers and warning signs and giving safety talks.
● Observe the nationally applicable health and safety regulations.
● It is forbidden for people with pacemakers to be close to the machine.
● Do not carry any magnetic or electronic data media.
