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 12.4.3 "Re-lubrication of the hybrid bearings" on
page 60 ).
● 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).
