10.3.2 Common DC bus fusing
DC bus fusing is required in the following systems for both the Regen and motoring drives, and the rectifier if used as the external soft start circuit.
1. Single Regen, multiple motoring drives
2. Multiple Regen, multiple motoring drives
3. Unidrive M Regen brake resistor replacement
4. Regen systems using a rectifier
DC bus fuses as detailed following must be fitted in both the positive and negative branches of DC bus connections to each of the Regen and
motoring drives, and the rectifier if used as the external soft start circuit.
Ferraz have a range of DC fuses which could be used to provide the required protection, types (00 and 21) may be used.
00 - Fuse with no trip indicator fitted
21 - Fuse fitted with trip indicator
The DC bus voltage set-point on a Regen system (default) is set to 700 Vdc, this can be up to a maximum 800 Vdc. Therefore ensure the selected
DC bus fusing is of the correct voltage rating with regards to the DC bus voltage level (Pr 03.005 DC Bus Voltage Set-point).
