CAUTION
Deionized water
Deionized water is harmful to eyes and skin and can damage surfaces.
● Therefore, use appropriate protective clothing for all work on the drive. However, if your
eyes or skin do come into contact with deionized water, rinse the affected area thoroughly
with tap water as soon as possible.
● If deionized water leaks out, eliminate the source of the problem and remove the liquid
from the surfaces affected.
NOTICE
Unsuitable residual current monitoring device
If you operate the drive together with a residual current monitoring device (RCD), it is possible
the residual current monitoring device will trip in error (nuisance trip). The drive 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.
2.5 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.
WARNING
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 converter.
NOTICE
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.
Nominated persons in control of electrical installations can find further information on
electromagnetic fields under "Information for persons responsible for plants and systems."
