Installation and connection
Laying connecting cables
Before installation of all devices, the connecting ca-
bles must be laid inside the distributor cabinet in
accordance with the locally applicable regulations
and all electrical interfaces must be protected from
contact.
e
Use suitable installation cables that comply with
the locally applicable regulations.
e
Cut the installation cables to length in accord-
ance with the space and installation positions.
e
Observe the product-specific bending radii of
the installation lines to avoid defects in lines and
hardware.
Connection to the building installa-
tion
NOTE
Incorrect assignment of the phases
Incorrectly assigned phases can lead to false results
and malfunctions.
In the case of a multi-phase power grid, ensure that
there is one phase at the house connection that
corresponds to the phase at the Porsche charger
connection and, if necessary, to the phase of an in-
verter of a photovoltaic system. There should be no
phase shift at any point, otherwise the phase-specific
charging functions will not work. With this installa-
tion, current converters can be assigned to the power
sources and power consumers inWeb Application in
normal phase sequence (e.g. L1-L2-L3) correspond-
ing to the phases of the voltage measurement.

All devices must be connected to the existing build-
ing installation in accordance with the locally applica-
ble regulations and standards.
Communication between the charging cable
and the energy manager
– The smart charging cable is multi-phase con-
nected (socket or fixed):
e
Make sure that the phases on the energy man-
ager and charging cable match.
–
The smart charging cable is single-phase con-
nected:
e
When assigning phases in theWeb Application,
use the phase to which the smart charging cable
is connected.
Connecting the external power supply unit
e
Follow the manufacturer's installation instruc-
tions.
g Refer to chapter "Applicable documents" on
page 4.
e
Connect the DC output to the energy manager
according to the terminal assignment of the con-
nector for the power supply (J102).
e
The power supply unit is connected to the en-
ergy manager with cables. Wiring the cables
must be done by a qualified electrician.
Connecting RS485/CAN communication
Information
No application for connection to RS485/ CAN in
the software (08/2019). For future functions, please
refer to the release information accompanying new
software versions.
When connecting the energy manager to the build-
ing installation, there is a risk that the DC power
supply connector (J102) will be accidentally inserted
into the port for RS485/CAN. This can damage the
energy manager. By plugging in the six-pin connec-
tor without the connecting cable (J1000), which is
included in the kit, you eliminate the possibility of
confusing the connections.
e
Plug the connector without connecting cable
into the J1000 connection in the energy man-
ager housing.
Connecting relay channels
Information
Does not have an application for connection to relay
channels in the software. For future functions, please
refer to the release information accompanying new
software versions.
The energy manager's scope of delivery includes a
corresponding plug connector without connecting
cable.
e
Insert the plug connector without connection
line into the connection J900/J901 in the hous-
ing of the energy manager.
