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

Damage due to moisture and humidity!
NOTICE
Use coverings to protect the products from moisture.
Store them only in rainproof and dry rooms.
Before storage, discharge the liquid coolant from liquid-
cooled motors to avoid damage.
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.
