Connection To The Building Installation - Porsche Home Energy Manager Manual

Installation and Connection
f Please see chapter "Overview" on page 4.
e Adhere to the maximum permitted cable length
US
of 9.8 ft. (3 m) per current sensor.
e Select an installation location with straight-
FC
routed cables and observe the direction of
measurement (arrow pointing towards the
electrical load) (Fig. 15, white arrow).
ESM
e Insert the installation cable into the current
sensor and close the cap of the current sensor
PTB
(Fig. 15, yellow arrow).
e Make sure that the rated current of the current
sensor is actually higher than that of the circuit
TR
breaker.
e Current sensor cables should be inserted into the
RU
plug connector first and only then should the plug
connecter be inserted into the device interfaces.
UK
Information
Note the current sensor type, the connection position
on the energy manager and the phase to which the
VIE
current sensor was attached. You will require this
information to configure the current sensors in the
HE
web application.
If measurement cables must be extended, use the
AR
same cable type where possible.
If the installation environment requires the use of an
optional wall-mounted distributor, the cables must
JPN
be guided through suitable cable routing systems
(cable ducts, channels etc.) into the wall-mounted
distributor.

Laying connection cables
The connection cables must be laid inside the
distributor cabinet before installation of any devices
in accordance 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 cables
and hardware.
Connection to the Building
Installation
Incorrect assignment of
NOTICE
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 manager
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
manufacturer.
f Please see chapter "Referenced Documents"
on page 3.
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
manager via cable. This cable must be prepared
by an electrically skilled person.
