Project Planning Manual | Rexroth MKE Synchronous Motors Electric Drivesand Controls| Bosch Rexroth AG 99/131Installation11 Installation11.1 SafetyWARNINGInjuries due to live parts! Lifting of heavy loads!⇒ Install the motors only when they are de-energized and not connected electrically.⇒ Use suitable tackles, protective equipment and protective clothing duringtransport.⇒ Observe the notes regarding safety found in previous chapters.11.2 Skilled PersonnelCarry out all working steps especially carefully. In this way, you minimize therisk of accidents and damage.Any work on the system and on the drives or in their vicinity may be carried outonly by appropriately trained technical personnel.Please make sure that all persons carrying out●●●Installation workMaintenance, orOperational activitieson the system are adequately familiar with the contents of this documentationas 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 electriccircuits and equipment according to the technical safety regulations. Qualifiedtechnical personnel must possess appropriate safety equipment and have beentrained in first aid.11.3 Mechanical Mounting – Motor Assembly11.3.1 Flange ConnectionTo attach the motors correctly and safely to the machine, Bosch Rexroth recommendsthe following screws and washers for motor mounting.The screwed connections must be able to take up both the forcedue to the weight of the motor and the forces acting during operation.For standard case, use pan-head machine screw DIN 912 - M... x ... - 8.8 andrelated washers according to DIN EN 28738. In case of several motors, theintegration of washers is not required, see table.If the screws and washers used do not comply with this recommdation,the stability class of the screws and the hardness class mustbe equivalent in order to transmit the required tightening torques(see Fig. 11-1).
