Fuses
It is recommended the use of fuses suitable for operation with direct current at the UP11 DC supply. The
maximum bus voltage at the 400 V line is 800 Vdc, at the other lines it is 1200 Vdc (IGBT overvoltage trip level).
Fuses used in AC lines can be used; however, a derating in the AC voltage must be applied. Consult the fuse
manufacturer in order to obtain the derating factor.
Fuses examples:
Line 400 V 10URD73TTF1000 (FERRAZ)
Line 600 V 12URD73TTF900 (FERRAZ)

UP11 Connections
The installation of the input connections of the UP11 is done with 4 screws M12X25 (recommended torque: 60
Nm); see Figure 2.11.
Figure 2.11:
Input links of the UP11; DC input connection [mm(in)]
The output connections in the internal reactance are done by means of 6 screws M12X30 (recommended
torque: 60 N.m); 2 screws are used for each phase. The links are 40X10 mm and the fastening is done
through
nut M12 inserted in the link, refer to Figure 2.1.
