Safety instructions
2.4 Safe handling
Risk of burns due to hot component surfaces
Certain components (e.g. heat sinks and reactors) can become very hot during operation.
These components can remain hot for a long time after operation. Contact can result in serious
injury, such as skin burns.
● After the device has been shut down, do not touch any hot components.
Risk of burns due to 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.
● Ensure that the anti-condensation heating cannot be touched.
● Ensure that the anti-condensation heating is switched off before carrying out any repair or
Risk of injury at 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 carry out work in the upper section using unsuitable ladders or similar,
you can fall and injure yourself.
● Use appropriate protective equipment, especially a hard hat and gloves.
● Use suitable steps or ladders when working in the upper area.
Eye and skin injuries caused by 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
● If deionized water leaks out, eliminate the source of the problem and remove the liquid from
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.
