11.3.2 Preparation
Prepare the motor assembly as follows:
1. Procure tools, supplies, measuring and test equipment.
2. Check all components for visible damaged. Defective components may
not be mounted.
3. Make sure that dimensions and tolerances on the system side are suitable
for motor attachment (for details, see the dimension sheet).
4. Check whether all components, assembly surfaces and threads are clean.
5. Make sure that the assembly can be carried out in a dry and clean envi‐
ronment.
6. Make sure that the holder for the motor flange is deburred.
7. Remove the protective sleeve of the motor drive shaft and keep it for fur‐
ther use.
8. Only for motors with holding brake
Check whether the motor holding brake reaches the holding torque speci‐
fied in the data sheet. Should the brake fail to reach the torque specified,
first grind in the holding brake as described in the Chapter9.11.5 .
11.3.3 Assembly
Please observe the following points during assembly:
1. Avoid pinching or jamming the centering bundle on the motor side.
2. Avoid damage to the insertion fitting on the system side.
3. Check the fit and precision of the connection before you proceed.
After proper mechanical assembly, make the electrical connections.
11.4 Electrical Connection
11.4.1 Notes Regarding Safety
It is recommended that you use ready-made Rexroth connection cables. These
cables provide a number of advantages, such as UL/CSA authorization, ex‐
treme load capability and resistance as well as a design suitable for EMC.
