2.9 System configuration

Figure 2-16 shows a typical water-cooled common DC bus drive system.
The water-cooled rectifier module converts AC voltage to DC voltage, and the DC voltage is distributed to all
inverter modules through the DC bus, then the water-cooled inverter modules convert the DC voltage to AC
voltage to drive the motor to rotate. An external DC fuse is required for the connection between each
inverter module and DC bus.

2.10 Electrical model selection

2.10.1 AC fuse

An AC fuse protects the rectifier unit in case of short circuit, avoiding thermal overload. The same brand
replacement principle should be followed. See the following table for selection.
