For a better overview, some essential environmental influencing variables of
the previously mentioned classifications are listed. Unless otherwise speci‐
fied, the specified values are the values of the particular class. However,
Bosch Rexroth reserves the right to adjust these values at any time based on
future experiences or changed environmental factors.

Before re-storage, empty the liquid coolant from the liquid-cooled
BA1N energy storage device to avoid frost damage.
BA1N energy storage device stor‐
age times
Irrespective of the storage duration - which can exceed the warranty period of
our products - the function is retained provided additional measures are taken
into account and carried out during commissioning. However, this does not
entail any additional warranty claims.
Storage time Measures for commissioning
1 ... 5 years
● Check the electric contacts to verify that they are free from
corrosion
● After a storage period of more than 2 years, the hybrid
bearings must be re-lubricated before commissioning (see
chapter 7.7.3 "Re-lubrication of the hybrid bearings" on
page 32).
● Let the BA1N energy storage device run in without load for
one hour at 800 ... 1000 rpm.
> 5 years
Send the BA1N energy storage device back to the Bosch
Rexroth service for overhaul (e.g. bearing or encoder replace‐
ment).
