2.4 Electromagnetic fields in electrical power engineering installations
Hot anti-condensation heating surface
When the temperature control limit value is reached the anti-condensation heating is switched
on. Once activated, the anti-condensation heating can generate a great deal of heat. Contact
can result in serious injury, such as skin burns.
Do not touch the anti-condensation heating.
Places that are difficult to access
If you do not use appropriate protective equipment when working in places that are difficult
to access you are at risk of injury. For example, sharp edges and splinters can cause injuries
to the head and skin. If you use unsuitable steps when working on the upper areas of the
drive, you can fall and injure yourself.
● Use appropriate protective equipment, especially a hard hat and gloves.
● In the upper areas of the drive, use suitable steps.
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.
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.
People with pacemakers are therefore not allowed to stay close to the drive.
