DC bus
Please observe the following information during installation:
Permissible cable lengths
•
Wiring shielding
•
Permissible fuses
•
Minimum capacities in the DC bus
•
The regenerative module is decoupled in the energy flow to the DC-bus connection. The
energy can only flow from the DC-bus connection to the regenerative module.
Switching operations in the DC-bus connection do not affect the regenerative module.
The DC bus in the regenerative module is charged on the DC or AC side via an internal
precharging circuit.

Preparation

The structure in the control cabinet must support the EMC-compliant installation with
•
shielded cables.
EMC requirements may need the use of shielded cables for wiring the DC bus.
•
The following serves to achieve a conductive support of a shielded cable on the shield
•
connection sheet:
Metal cable ties, e. g. EZAMBKBM/M
-
Shield mounting with EMC wire clamps
