3.4.3Supply via the DC bus

A single or multiple drives can be supplied directly via the DC bus.

The supply is provided by a correspondingly sized drive or by a DC power supply unit.

In the case of supply via the DC bus, DC bus fuses must be used. The DC bus fuses must be suitable for 600 Vdc.

The number of DC bus fuses depends on the total maximum continu- ous current on the DC bus of all drives connected via the common DC bus.
