Note
If the objective is that an application is not to have a leading contact over the
complete power range of the infeed modules, then this can be implemented
using the following measures:
S
S
The I/R modules then operate as UI modules and can be operated with
additional loads connected to a switching element without leading contact.
Leading contact is
For the configurations that are now described, a leading contact for the switch-
absolutely ing element is absolutely necessary:

The following diagram shows two examples where a leading contact is abso-

Changing over from any present I/R modules to unregulated infeed (this is
generally the case for 480 V applications).
Deactivating the regenerative feedback if I/R modules are being used.
If one or more I/R modules are connected, together with other loads, through
a switching element.
If NE modules having different power classes are connected together to one
switching element. In this case, the restrictions, described on the following
page, must be carefully fulfilled.
