According to DIN EN 60721-3-3, Tab. 6, edition 1994, IndraDyn T motors can
be operated in stationary weather-protected locations under the following con‐
ditions:
Direction
axial
radial

●
Ensure that the maximum values specified in and for storage,
transport, and operation of the motors are not exceeded.
●
The construction and effectiveness of shock-absorbing or
shock-decoupling attachments depends on the application
and must be tested using measurements. This does not lie
within the area of responsibility of the motor manufacturer.
Modifications of the motor construction result in nullification of
the warranty.
Climatic environmental conditions are defined into different classes according
to DIN EN 60721-3-3, Table 1. They are based on observations made over long
periods of time throughout the world and take into account all influencing quan‐
tities that could have an effect, such as the air temperature and humidity.
Based on this table, Rexroth recommends class 3K4 for continuous use of the
motors.
This class is excerpted in the following table.
