NOTE!
The voltage must be compatible to the rectifier rated voltage. Refer to item 3.4.6.4 Control Connections
on page 3-18 for the configuration of the UR11 rated operation voltage.
The fastening of the UR11 output connections is done with four M12 x 25 bolts (tightening torque: 60 N.m.), as
presented at
Figure 3.14 on page 3-14 . Refer to item 3.4.2 Cables/Bus Bars on page 3-6 for more information.

Figure 3.14 - UR11 output bus bar, DC connections (mm [in])
The input connections at the internal reactances are done by means of twelve M12 x 30 bolts (tightening torque:
60 N.m.), each reactor uses 6 bolts, 2 bolts per phase. The bus bars are of 40 x 10 mm (1.57 x 0.39 in) and
the fastening is done through M12 nuts inserted into the bar, as presented at
Figure 3.15 on page 3-15 .
