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