NOTICE
Dust deposits prevent heat radiation
Dust deposits prevent heat radiation and cause a high housing temperature.
Keep the gearbox free from dirt, dust, etc.
The gearbox does not normally require additional cooling. The generously dimensioned
housing surface is sufficient for dissipating heat losses where there is free convection. If the
housing temperature exceeds a value of +80 °C, please contact Technical Support.
2.4 Rating plate
The rating plate on the gearbox or geared motor is of coated aluminum foil. The rating plate
is glued using a special masking film. The film ensures permanent resistance to UV radiation
and media of all kinds, such as oils, greases, salt water and cleaning agents.
The adhesive and the material ensure firm adhesion and long-term legibility within the
operating temperature ranges from -40 °C to +155 °C.
The edges of the rating plate are paint-finished to match the color of the gearbox or motor to
which it is affixed.
