General description of inverter input terminals

Starting current limiting
When connecting inverters to a DC bus pay attention to the internal wiring of the
DC voltage inputs !
Inverters that directly output the DC link bus to the DC terminals must be inte-
grated into the DC bus by way that the supply unit(s) limit the starting current.
The precharging must be completed within two seconds.
Maximum DC link capacity
The maximum DC link capacity can be calculated by adding the DC link capac-
ities of all inverters in the DC bus. A table for this can be found in the appendix.
The supply source (rectifier module or inverter with AC input) must be suitable
for this value.

Description of terminals at KEB inverters
DC voltage input with starting current limiting; usable as output only if all
devices supplied by the DC bus have a starting current limiting at the DC
voltage input.
DC voltage output with starting current limiting; usable as input only if the
starting current is limited by the supply source.
Connection for braking resistor; optionally only if a braking transistor is
installed
Mains input 3-phase
