Combivert R6-S - KEB Combivert R6-S Instruction Manual

Connection Power Unit R6-S
4.4.3 Power supply and regeneration at inverter currents ≥inverter current of one COMBIV-
ERT R6-S

1) If the inverter current > inverter current of the COMBIVERT R6-S, it must be wired at an external termi-
nal (6).
2) The cable cross-section may not be smaller than 10 mm². It must be dimensioned for the DC rated
current of the load. Otherwise appropriate fuses in the DC bus (7) are required. The indicated maximum
protection for the connected drive controllers must be observed !
3) In case of parallel connection of R6-S the total power can be smaller up to 10 % caused by production
tolerances of the commutation reactor. The impedance voltages uk of the commutation reactors must
be the same in case of parallel connection of R6-S with different sizes.
4) Mains and DC fuses must be monitored.
5) If R6 devices without internal DC-fusing are used, fuses in accordance with annex B.1.2 must be used
to be conform according to UL. The specified fuses there refer to a maximum fusing of the R6 devices.
Lower fuse protection according to the connected inverter can be done with fuses of the same type.
When connecting the devices absolutely pay attention to correct phasing !
A load draw from the DC circuit may be done only if the ready signal is active.

Parallel operation
When connecting in parallel operation, the parameter default set must be
changed. See application instructions R6-S under "Special functions for parallel
connection".
