minutes! The time required for cooling down is approximately five times
the thermal time constant specified in the technical data.
● After switching chokes, supply units and drive controllers off, wait 15 mi‐
nutes to allow them to cool down before touching them.
● Wear safety gloves or do not work at hot surfaces.
● For certain applications, and in accordance with the respective safety
regulations, the manufacturer of the machine or installation must take
measures to avoid injuries caused by burns in the final application.
These measures can be, for example: Warnings at the machine or in‐
stallation, guards (shieldings or barriers) or safety instructions in the ap‐
plication documentation.

3.3.7 Protection against pressurized systems
According to the information given in the Project Planning Manuals, motors
and components cooled with liquids and compressed air can be partially sup‐
plied with externally fed, pressurized media, such as compressed air, hy‐
