Page 9: Mounting Optional Accessories
5 Mounting optional accessories 5.1 Mechanical or inductive limit switches For details regarding the technical characteristics of the limit switches please see the catalogue. Ensure that the cable is laid in a safe way. Avoid damages to the cable e. g. due to small radiuses; this may lead to failure of the system. The cable must not enter the travelling path of the linear system. -
Page 10: Mounting Coupling
5.3 Mounting coupling There are two methods to install the motor, either without gears or with a planetary gear. The manufacturing tolerance are very low, therefore we recommend buying the adapter directly from Bahr Modultechnik. Angular misalignments and misalignments with respect to the centre of the adapter can lead to serious damages at the coupling and the bearings. -
