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.

The power supply units can alternatively be used as an external supply for the control electronics of frequency and servo inverters. Through their use, parameterization and diagnostics can be carried out without mains supply. This helps during commissioning and when servicing the inverter. 
The E94AZ RFI and mains filters for the i700 cabinet inverters are used to ensure compliance with the EMC requirements of European Standard EN 61800-3 and are easy to use for categories C1 - C3. Mounting is done next to the inverter. 
The I0FAE RFI and mains filters for the i510 cabinet, i550 cabinet, and i950 cabinet inverters are used to ensure compliance with the EMC requirements of European Standard EN 61800-3 and are easy to use for categories C1 - C3. Mounting is done under or next to the inverter.
By using an EZAELN3 mains choke, harmonics at the mains input of a 3-phase inverter are smoothed. For large powers, the use of a mains choke is mandatory. 
By using an ELN1 mains choke, harmonics at the mains input of a 1-phase inverter are smoothed. For large powers, the use of a mains choke is mandatory. 
If the machine has to be braked or brought to a standstill in a short time, the motor at the inverter runs in regenerative mode. The resulting energy can be dissipated with a brake resistor.  The ERBU brake resistors are designed as metal cartridges and are mounted directly on the inverter. They are connected via a ready-made connecting cable and since they are intrinsically safe, no temperature monitoring is required.
