Installation and Assembly<br />
•= the minimum required screw-in depth and the tightening torque for the clamping<br />
bolts as given in the following table are observed. These differ depending on<br />
whether cable lugs or earth terminals are used:<br />
Table 3-3 Tightening torques of bolts (cable lug)<br />
Bolt Screw-in depth Tightening torque<br />
M12 x 25 > 16 mm 38 Nm<br />
M16 x 35 >20 mm 92 Nm<br />

3.5.4 Connecting the main circuit<br />
General<br />
Remove the insulation from the conductor ends, so that the remaining insulation is<br />
almost long enough to reach the cable lug. Insulate cable lug sleeves in order to<br />
maintain the clearances in air.<br />
Note<br />
The current-carrying capacity of the connection is guaranteed using the CuZn<br />
contact nuts. These nuts must not be replaced by parts manufactured out of<br />
different materials.<br />
Note<br />
Connection points are available on the bearing end shield for connecting a bonding<br />
jumper.<br />
Connection with cable lugs<br />
Select the cable lugs corresponding to the required cable cross-section and the<br />
specified dimensions of the clamping point (terminal size M16). The tightening<br />
torques for the contact and fastening nuts are 40 Nm.<br />
