Shutdown as a result of an incorrect residual current monitoring device
If you use a residual current monitoring device (RCD), it is possible that the residual current
monitoring device will trip in error (nuisance trip). The converter may be switched off as a result
of the protection device tripping in error.
● To minimize the risk of faulty trips, use a type-B RCD.

Electromagnetic fields in electrical power engineering installations
Electromagnetic fields are generated during operation of electrical power engineering
installations. Electromagnetic fields can interfere with electronic devices, These devices can
malfunction if electromagnetic fields are present.
Interference with pacemakers
The functioning of cardiac pacemakers could be impaired by electromagnetic fields. Death or
serious physical injury can result.
● It is therefore not permissible for people with pacemakers to stand close to the device.
Data loss
Electromagnetic fields can cause data loss to magnetic or electronic data storage media.
● Therefore, do not carry magnetic or electronic data storage media with you.
Persons responsible for plants and systems can find additional information on electromagnetic
fields under "Information for persons responsible for plants and systems (Page 20)."
2.6
Components that can be destroyed by electrostatic discharge (ESD)
ESD guidelines
Material damage caused by electrostatic discharge.
Electronic components can be destroyed in the event of improper handling, transport, storage,
and shipping.
Pack the electronic components in appropriate ESD packaging; e.g. ESD foam, ESD
packaging bags and ESD transport containers.
To protect your equipment against damage, follow the instructions given below.
● Avoid physical contact with electronic components. If it is essential that you perform work on
● Do not place electronic components close to data terminals, monitors or televisions.
SINAMICS SM150 6SL3815-7NP41-0AA1
Operating Instructions Rev.201910281301 EXAMPLE
2.6 Components that can be destroyed by electrostatic discharge (ESD)
these components, you must wear one of the following pieces of protective gear:
– Grounded ESD wrist strap
– ESD shoes or ESD shoe grounding strips if there is also an ESD floor.
Maintain a minimum clearance to the screen (> 10 cm).
