4.3.2 Connection terminals of the power circuit
All terminal blcoks meet the requirements on EN 60947-7-1 (IEC 60947-7-1)
View of power supply and regenerative units
The terminals of a power supply and regenerative unit can be input or output dependent on the actual
operating status (power supply or regeneration). For the standardization of the view the line side is always
regarded as input and the DC voltage side is always regarded as output.

Terminals Description of terminals at KEB inverters
++, – – DC voltage output with starting current limiting for loading the connected inverters; usable as input
for regenerative operation. If inverters with mains supply of type A1 or A2 (see 4.3.1) are available
in the DC bus, these may be switched to mains only after loading the DC bus. Note the maximum
DC link capacity or decoupling diodes !
L1.2, L2.2, L3.2 Mains input 3-phase coming from the commutation choke
