Climatic environmental conditions are defined according to different classes
as specified in DIN EN 60721-3-3, Table 1. They are based on long-term ex‐
periences and take all influencing variables into account, e.g., air temperature
and air humidity.
BA1N energy storage devices may be continuously operated within the limit
ranges of class 3K4. The following table provides extracts of this class.
Environmental influences
Low air temperature
High air temperature
Low rel. air humidity
High rel. air humidity
Low absolute air humidity
High absolute air humidity
Temperature change rate
1)
The lowest air temperature allowed by Rexroth is 0°C.

Classification of climatic ambient conditions according to DIN EN
60721-3-3, Table 1
Vibrations are sinusoidal oscillations in stationary use, which vary in their ef‐
fect on the resistance of the energy storage devices depending on their inten‐
sity. The resistance of the overall system is determined by the weakest com‐
ponent.
Based on DIN EN 60721-3-3 and DIN EN 60068-2-6 , the following values
are allowed for BA1N energy storage devices:
Direction
Axial
Radial
Tab. 9-2:
Maximum values for sinusoidal vibrations
The construction and effectiveness of vibration-absorbing or vibration-decou‐
pling attachments depends on the application and must be tested using
measurements. Rexroth shall not be held responsible for this measurement.
