Connection Terminals Of The Power Circuit - KEB COMBIVERT R6-S Series Instruction Manual

4.3.2

Connection terminals of the power circuit

All terminal strips 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
standardization, the line side is always regarded as input and the DC voltage
side is always regarded as output.

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 !
