6.3.1 General description of inverter input terminals
Starting current limiting
When connecting inverters to a DC bus pay attention to the internal wiring of the
DCvoltageinputs!
Inverters that directly output the DC link bus to the DC terminals must be inte-
gratedintotheDCbusbywaythatthesupplyunit(s)limitthestartingcurrent.
The precharging must be completed within ten seconds.
Maximum DC link capacity
The maximum DC link capacity can be calculated by adding the DC link capaci-
ties of all inverters in the DC bus. A table for this can be found in the appendix.

value.
Terminals Description of terminals at KEB inverters
++, – – DC voltage input with starting current limiting; usable as output only if all
units supplied by the DC bus have a starting current limiting at the DC volt-
age input.
+(PA),- DC voltage output with starting current limiting; usable as input only if the
starting current is limited by the supply source.
PA, PB Connection for braking resistor; optionally only if a braking transistor is
installed
L1, L2, L3 Mains input 3-phase
