Downgrade input
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
To reduce the charging current for each individual
charging point, an external 230 V control signal is
required for each charging point. The control signal
can be generated, for example, by an external load
shedding relay or an external time switch. As soon
as the 230 V control signal is applied to the down-
grade input, the charging current is reduced ac-
cording to the set configuration in the web inter-
face.
It is also possible to reduce the charging current for
the purpose of load management on the entire
charging point network. A detailed description can
be found on our website in the download section
for the selected product.
Installation
ATTENTION
Material damage due to improper installation
Improper installation can damage the product or
L1'
lead to malfunctions. Observe the following require-
L2'
ments during the installation:
L3'
u The control signal voltage must not exceed 230
N'
V.
PE'
u Select suitable cable routing to avoid interfer-
ence.
u Provide for secure separation of the remaining
installation from the highest occurring voltage.
1 Observe the circuit diagram.
Fig. 11: Downgrade input connection
Two external conductors (L) (230 V AC) and one
neutral conductor (N) are required for the connec-
tion.
u Strip the insulation on the cables.
u Strip the insulation on the conductors 8 mm.
u Connect the conductors to the switching input
(push-in connection).
