4.4 Connecting the busbars
The busbars are located in the back of the cabinets. To access them, it might be necessary to take
out the drives. See the instructions in Chapter 5.3.
Join together the DC, AC and PE busbars by bolting them together with baying brackets. The
mounting bolts, nuts and washers are delivered in place.
The busbars, size of the nuts and bolts differ case-by-case. See the correct tightening torque values
for different size bolts and different types of connections in Chapter 4.7.
