The frequency and servo inverters can be operated in a DC bus connection. The 400 V devices have a direct connection for this purpose. The fuses, busbars and accessories listed here are the complete set required for such operation.
A DC-bus connection can be used to balance the energy between the individual inverters. Especially in cyclic operation of several devices such an operation makes sense. The dimensioning of a DC-bus connection requires a very exact dimensioning of the energy requirements of the devices among each other.
