11 Installation
11.1 Safety
WARNING
Injuries due to live parts! Lifting of heavy loads!
⇒ Install the motors only when they are de-energized and not connected elec‐
trically.
⇒ Use suitable tackles, protective equipment and protective clothing during
transport.
⇒ Observe the notes regarding safety found in previous chapters.
Carry out all working steps especially carefully. In this way, you minimize the
risk of accidents and damage.
11.2 Skilled Personnel
Any work on the system and on the drives or in their vicinity may be carried out
only by appropriately trained technical personnel.
Please make sure that all persons carrying out
● Installation work
● Maintenance, or
● Operational activities
on the system are adequately familiar with the contents of this documentation
as well as with all warnings and precautionary measures contained therein.
Qualified skilled personnel are defined as those who have been trained,
instructed or are authorized to activate and deactivate, ground and mark electric
circuits and equipment according to the technical safety regulations. Qualified
technical personnel must possess appropriate safety equipment and have been
trained in first aid.
11.3 Mechanical Mounting – Motor Assembly
11.3.1 Flange Connection
To attach the motors correctly and safely to the machine, Bosch Rexroth rec‐
ommends the following screws and washers for motor mounting.
The screwed connections must be able to take up both the force
due to the weight of the motor and the forces acting during opera‐
tion.
For standard case, use pan-head machine screw DIN 912 - M... x ... - 8.8 and
related washers according to DIN EN 28738. In case of several motors, the
integration of washers is not required, see table.
If the screws and washers used do not comply with this recomm‐
dation, the stability class of the screws and the hardness class must
be equivalent in order to transmit the required tightening torques
(see Fig. 11-1).
