6.3.5 Connection with cable lugs
1. To connect the cables to the main terminals, select cable lugs that match the necessary
cable cross-section and appropriate screw size.
The connectable cable cross section is determined by the cable lug size for example.
– Cable lug in accordance with DIN 46234 from 35 mm

,
– Cable lug in accordance with DIN 46235 from 35 mm

.
Observe the possible outer diameter of the connecting cable in the chapter entitled
"Electrical connection data".
Connect only one conductor per cable lug.
2. Remove the insulation from the conductor ends so that the remaining insulation is almost
long enough to reach the cable lug.
