Basic safety principles
Danger to life due to elec-
trical voltage!
There is a risk of injuries due to electric shock and/or
burns, possibly resulting in death.
eDuring all work, make sure at all times that
power to the system is switched o and secured
so it cannot inadvertently be switched on.
eDo not open the housing of the energy manager
under any circumstances.
Proper use
The energy manager is primarily used to safeguard
the electricity supply (overload protection) by pre-
venting the building's main fuse from tripping.
The following count as improper use:
–Carrying out your own modications or additions
to the energy manager
–Any other use of the energy manager not descri-
bed in these instructions
The energy manager is designed as a series instal-
lation device. Installation must be performed under
electrical and information-related conditions.
eIn electrotechnical terms, the energy manager
must be installed in a suitable distribution box.

Installation and connection
NOTICE
eMake sure that all materials that protect against
corrosion are removed from the current con-
verter.
eAdhere to the maximum permitted cable length
of 3.0 m for each current converter.
eSelect an installation location that allows cables
to be routed straight, and pay attention to the di-
rection of measurement (arrow pointing towards
the load) ((Fig.), yellow arrow).
eInsert the installation cable in the current con-
verter and close the converter cap ((Fig.14),
yellow arrow).
eMake sure that the current converter actually has
a higher rated current than the circuit breaker.
eFirst insert the current converter cables in the
connectors, then insert the connectors in the
sockets of the device.
Information
Make a note of the type of current converter, its
connection position in the energy manager, and the
phase (e.g. L1 or L2) to which the current converter
was attached. You will need this information for con-
guring the current converters in the Web Applica-
tion.
If you need to extend the measurement leads, use the
same type of lead if possible.
If the installation environment requires the use of
the optional wall-mounted distribution box, route the
leads into this distribution box via suitable cable
guide systems (empty conduits, cable ducts, etc.).
Fig.14: Installation example of current converter
Routing connecting cables
Before installing any equipment, route the connect-
ing cables inside the distribution cabinet in accord-
ance with local regulations, and protect all electrical
interfaces from contact.
eUse suitable installation cables in accordance
with local regulations.
eCut the installation cables to length to suit the
available space and installation locations.
eMake sure the installation cables comply with
the product-specic bending radii, to prevent
faults with cables and hardware.
Connection to the building installa-
tion
Incorrect phase assignment
Incorrectly assigned phases can lead to incorrect re-
sults and malfunctions.
With a multiphase power grid, make sure that a
phase in the domestic connection matches the phase
at the Porsche charger connection and, if applicable,
the inverter phase of the photovoltaic system. Phase
shis should not exist anywhere, as otherwise the
phase-individual charging functions will not work.
With this installation, you can assign current convert-
ers to power sources and current converter in the
Web Application in the normal phase sequence (e.g.
L1-L2-L3), as for the voltage measurement phases.
Connect all devices to the existing building installa-
tion in accordance with local regulations and stand-
ards.

15
Charging cable communication with the en-
ergy manager
–The intelligent charging cable features a multi-
phase connection (electrical socket or perma-
nently installed):
eMake sure that the phases of the energy man-
ager and the charging cable match.
–The intelligent charging cable features a single-
phase connection:
eWhen assigning phases in the Web Application,
use the phase to which the intelligent charging
cable is connected.
Connecting an external mains power supply
unit
eFollow the manufacturer's installation instruc-
tions.
gRefer to chapter "Applicable documents" on
page 3.
eConnect the DC output to the energy manager
using the terminal assignment of the connector
for the power supply (J102).
eConnect the mains power supply unit to the en-
ergy manager via cables. These cables must be
prepared by a qualied electrician.
Connecting RS485/CAN communication
Information
The soware (08/2019) does not cover the connec-
tion to RS485/ CAN. For future features, please pay
attention to information on new soware releases.
When connecting the energy manager to the building
installation, there is a risk of inserting the DC power
supply connector (J102) into the RS485/CAN port
by mistake. This can damage the energy manager.
By inserting the 6-pin connector without connecting
cable, included in the scope of supply (J1000), you
will avoid interchanging connectors.
eInsert the connector without connecting cable
into socket J1000 in the housing of the energy
manager.
Connecting relay channels
Information
The soware does not cover the connection to relay
channels. For future features, please pay attention to
information on new soware releases.
The energy manager scope of supply includes a suit-
able connector without connecting cable.
eInsert the connector without connecting cable
into socket J900/J901 in the housing of the
energy manager.
Connecting current and voltage measure-
ment
The current and voltage measurement channels are
connected via several plug connections. The required
connectors are included in the energy manager scope
of supply. If the current converters or voltage meas-
urement leads are not connected, or connected in-
correctly, function will be extremely restricted.

your device (PC, tablet or smartphone) and the en-
ergy manager must be in the home network (via WiFi,
PLC or Ethernet connection).
All the functions of the Web Application can be used
via the internet connection of the home network. The
network connection of the device via an Ethernet
cable is recommended. If there is no home network
available at the place of use, your device can log in to
the energy manager directly via its WiFi hotspot.
eThe Home Energy Manager operates exclusively
in the 2.4 GHz network (see gP.32)
eSelect the connection type suitable for the pre-
vailing signal strength and availability.
Connecting the WiFi antenna
You can connect a WiFi antenna to boost the WiFi
signal.

16
Installation and connection
1. Connect the WiFi antenna to the energy man-
ager via the plug-in/screw connections provided
for this purpose.
2. Secure the WiFi antenna to the outside of the
metal distribution cabinet by its magnetic base
(if the WiFi antenna is inside the metal distribu-
tion cabinet, it cannot receive a signal). Make
sure that the WiFi antenna is positioned cor-
rectly (e.g. at an angle of 90° to the router).
Checking the signal quality of the PLC net-
work
Information
The soware and Ethernet PLC converter described
in this section are not included in the scope of supply.
To check the connection quality of the PLC network,
you can determine the PLC data transfer rate through
the domestic electrical system using soware and
Ethernet PLC converters. For this purpose, connect
the converters to the mains supply at the installation
locations. Select the installation locations of the en-
ergy manager and the current consumers with PLC
functionality (such as the Porsche charger) as instal-
lation locations for this. The real data transfer rate
between the installation locations can be visually dis-
