Connection To The Building Installation - Porsche 9Y0.915.686 Manual

Laying connection cables
The connection cables must be laid inside the distrib-
utor cabinet before installation of any devices in ac-
cordance with the locally applicable regulations and
all electrical interfaces must be protected against
contact.
e
Use suitable installation cables that comply with
the locally applicable regulations.
e
Cut the installation cables to length to suit the
space available and the installation position.
e
Observe the product-specific bending radii of
the installation cables to prevent damage to ca-
bles and hardware.
Connection to the building installa-
tion
NOTICE
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
one phase of the domestic connection corresponds
to the phase at the Porsche charger connection and,
if required, the phase of an inverter of a photovoltaic
system. At no point should there be a phase shift, as
otherwise the phase-specific charging functions will
not work. With this installation, current sensors can
be assigned to the power sources and electrical loads
in the Web Application in the normal phase sequence
(e.g. L1-L2-L3), which corresponds to the phases of
voltage measurement.
The connection of all devices to the existing building
installation must take place in accordance with the
locally applicable regulations and standards.
Communication between the charging cable
and energy manager
– The intelligent charging cable has a multi-phase
connection (electrical socket or permanently
mounted):
e
Make sure that the phases at the energy man-
ager correspond to those of the charging cable.
– The intelligent charging cable has a single-phase
connection:
e
When assigning phases in the Web Application,
use the phase to which the intelligent charging
cable is connected.
Connecting an external power pack
e
Follow the installation instructions of the manu-
facturer.
g Refer to chapter "Referenced Documents" on
page 5.
e
Connect the DC output in accordance with the
terminal assignment of the plug connector for
the power supply (J102) to the energy manager.
e
The power pack is connected to the energy man-
ager via cable. This cable must be prepared by a
qualified electrician.
Connecting RS485/CAN communication
Information
No application for the connection to RS485/CAN in
the software (08/2019). For future functions, please
note the release information on the new software
versions.
When connecting the energy manager to the building
installation, there is the risk that the plug for the DC
power supply (J102) will be inadvertently plugged
into the port for RS485/CAN. This can cause damage
to the energy manager. By plugging in the six-pin
plug connector without connection cable (J1000),
which is included with the items supplied, you will
exclude the possibility of the connections being con-
fused.
e
Insert the plug connector without connection
cable into the J1000 connection in the energy
manager housing.
Connecting the relay channels
Information
No application for the connection to relay channels in
the software (08/2019). For future functions, please
note the release information on the new software
versions.
The scope of supply of the energy manager includes
a corresponding plug connector without connection
cable.
e
Insert the plug connector without connection ca-
ble into the J900/J901 connection in the energy
manager housing.
