Fig. 9-3: Maximum values for shock load
⇒ Ensure that the maximum values for storage, transport and operation
of motors as specified in Figs. 9-4 and 9-5 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.
Ambient Climatic Conditions
Ambient climatic 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 quantities 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.
