The following table specifies the rms values of the line currents which occur at the beginning of the precharging
process in the case of line supply voltages 400 V or 690 V. Where other line voltage values apply, the values must be
converted in proportion to the line voltage.
The specified precharging currents decay in accordance with an e-function until the precharging process is
completed after a period of typically 1 to 2 s. Due to the temperature rise in the precharging resistors during the
process, the minimum permissible interval for complete precharging of the DC link is 3 minutes.

8.6 Load side components
8.6.1 Line fuses
The use of combined fuses (3NE1..., class gS) is recommended in order to limit the extent of damage in the event of
a serious component defect in the converter. These fuses have the following properties:
· Quick-acting
· Low arc voltage
· Effective current limiting.
