A 10 A-fuse is incorporated in the auxiliary power modules to protect the 24 V DC-auxiliary
voltage. The order number for this fuse as a spare part is 6SL3760-0BG00-0AA0.
Fuse type: TAC ATO flat plug-in fuse according to DIN 72581-3, UL 248 Special Purpose
Fuses, 10 A, 58 V, manufacturer: Littlefuse
Table 4- 7 Voltage assignment for connecting cables
4-phase
Line voltage:
• 380 to 480 V 2 ph. AC
• 500 to 690 V 2 ph. AC (max. 759 V AC)
2
230 V 1 ph. AC (max. 265 V AC)
2-phase 1 24 V DC for the electronics power supply (max. 30 V DC)
The cable marked "1" must be connected to terminal 5 on the terminal block. The cable
marked "2" must be connected to terminal 6 on the terminal block.

Risk of death due to hazardous voltage resulting from incorrect voltage assignment
Incorrect voltage assignment on the auxiliary power supply system may result in high
voltages on components not suited for them, thereby damaging or destroying these
components. Touching these high voltage may result in death or serious injury.
• When carrying out any connection work to the auxiliary power supply system, avoid
confusing the poles of the voltage supply.
