■
Condensation drain hole
Condensation can accumulate inside the motor as the result of
environmental effects. This can result in corrosion and lower
clearances and creepage distances.
The condensation is drained to the outside through the conden-
sation drain hole. Depending on the mounting position, the drain
holes are located at the DE and/or NDE of the motor.
For gearbox F.29, a condensation drain hole is not possible for
mounting position M3.
For gearbox Z19, a condensation drain hole is only possible for
mounting position M2.

Internal motor corrosion protection
The outer surfaces of the geared motors have a high quality
paint finish.
For special applications, it may be necessary to apply a protec-
tive coating to the inner surfaces of the motor as well.
