Use cases

6.2.1 Downgrade

The tasks described in this section may only
be carried out by a qualified electrician.
By using the downgrade input, it is possible to re-
duce the grid connection charging current that is
not available at its maximum level under certain cir-
cumstances or at certain times. For example, the
downgrade input can be controlled by the following
criteria or control systems:
n Electricity rate
n Clock position
n Load shedding
n Manual control
n External load management
In the delivery state, the downgrade input is con-
trolled as follows:
Switching contact Downgrade status
status
open Downgrade active
closed Downgrade inactive
The configuration tool is required to change the lo-
gic of the downgrade input.
