11.2 Storage instructions
11.2.1 Storage conditions
Generally, Bosch Rexroth recommends to store all components until they are
actually installed in the machine as follows:
● In their original package
● At a dry and dustfree location
● At room temperature
● Free from vibrations
● Protected against light or direct insolation
On delivery, protective sleeves and covers may be attached to our motors.
They must remain on the motor for transport and storage. Do not remove
these parts until shortly before assembly.
Based on EN 60721-3-1, the tables below specify classifications and limit
values which are allowed for our products while they are stored. Observe the
detailed description of the classifications to take all of the factors which are
specified in the particular classification into account.

For the sake of clarity, a few essential environmental factors of the
aforementioned classifications are presented below. Unless otherwise
specified, the values given 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 ambient factors.
