Important
information
• Installation and servicing of the device must
be performed by qualied and authorized
persons, and repairs may only be carried out
by the manufacturer or entities authorized by
the manufacturer.
• Tampering with the mechanical, electrical
and electronic components and the device
software is forbidden and shall result in the
nullication of the warranty. The exceptions
include operations described herein and those
agreed in writing with the manufacturer.
• The manufacturer is not responsible for
damage to property resulting from the
forbidden interference in the product.
• The electrical installation to be used by the
device during its operation must meet the
conditions described in the installation manual.
The manufacturer is not responsible for
incorrect assembly and/or protection of the
electrical installation to which the device is
connected.
• The manufacturer is not responsible for the
malfunction of the electrical installation to
which the device is connected.
• The electrical installation to be used by the
device during its operation must comply with
the legal standards in force in the place of
assembly and the operation of the device.
• The manufacturer is not liable for any damage
caused by an electrical installation that does
not meet legal standards.
• The device does not have a built-in switch.
• The device activates when the supply voltage
is applied. The power supply cut off function
must be provided by the appropriate electrical
installation devices described in the assembly
manual. Except in emergencies, the device
must not be turned off during the charging
process.
• It is forbidden to supply the power to the
device when the device casing remains open.
• The manufacturer is not responsible for loss
of health or life by any persons resulting from
failure to comply with the above-mentioned
recommendations.
• The AC charger station to which the Energy
Guard will be connected, must be updated to
the latest software version and DLB function
activation it is required, which is described in
this manual.
General provisions:
Safety instructions
• All operations described in this manual should
be performed only after making sure that there
is no voltage in the power cord.
• Outdoor installation should not be carried out
during precipitation or strong wind, if there is a
risk of water or dirt getting into the device.

General
informations
ENELION ENERGY GUARD 3.0 (EEG 3.0) is
an intelligent energy meter that connects to
the ENELION LUMINA charger to optimize
the utilization of available electrical power in a
home. ENELION ENERGY GUARD measures
real-time power consumption at the electrical
connection point and sends measurement re-
sults to the ENELION LUMINA charger, allowing
the charger to limit its charging power to avoid
exceeding the maximum power supplied by the
connection. Current measurement is per-
formed using current transformers, signicantly
simplifying the installation.

ENERGY GUARD 3.0 in the network

Example of installing ENELION ENERGY
GUARD 3.0 in the network: ENELION ENERGY
GUARD 3.0 communicates wirelessly with ENE-
LION LUMINA chargers using Wi-Fi Mesh. The
connection conguration is described in the
‘Connecting ENELION ENERGY GUARD to the
ENELION charger network’ chapter on page 18.
Normally, ENELION ENERGY GUARD comes
with a set of current transformers selected at
the time of ordering. One current transformer
is allocated for each phase. Using current trans-
formers with different parameters will result in
incorrect measurements.
Current transformers are available in various
measuring ranges, from 50 A to even 3000 A.
Current transformers with a maximum input
current of 100 A and 300 A have a hole diame-
ter of 26 mm, while those with 500 A or 1000 A
have a diameter of 36 mm.
General information
Fig. 2: Sample current transformer
It is possible to order only the EEG 3.0
from Enelion and purchase the appropriate
current transformers separately. When
purchasing current transformers individually,
the following requirements must be met:
• Secondary current: 5 A,
• Accuracy class no worse than 1.

Electrical
Connection
Recommendation
01
ENELION ENERGY GUARD 3.0 is designed for
supplying power in both ve or three-wire con-
gurations (excluding the protective PE wire)
and is compatible with TN-S, TN-C, TN-C-S,
and TT network types.
The ENELION ENERGY GUARD device
can operate in either a 3-phase or 1-phase
setup. This manual is based on the three-
phase version. All connections should be
made considering the number of phases.
02 Location
Selection
Criteria
The device is designed for installation inside a
distribution board, near the power cables where
measurement transformers should be applied.
Installation of the device in easily accessible
locations is prohibited
!

9
The device should not be placed in areas of
direct sunlight that could cause overheating of
the device.
Do not install the device near heat sources or in
locations exposed to high humidity.
Installation of the device in explosion hazard
zones is prohibited. Before installation, ensure
that the mounting space inside the distribution
board for the device is sufcient.
Design guidelines for installation
There is the option to choose the installation
location for the measurement transformers.
They can be installed on the power cables
supplying the building’s load along with the
charging stations [Figure 3] or on the power
cables supplying only the building’s load
[Figure 4].
i
Selection of the measuring point – the location
of current transformers installation. Current
transformers can be installed in the distribution
board in two ways.
The rst method is to install them on the main
incoming power cables to the distribution
board. As a result, EEG will measure the current
for the entire connection [Figure 3].
The second option is to install them on the pow-
er cables supplying other loads (excluding the
ENELION LUMINA charging station) [Figure 4].
This information is crucial when conguring
DLB in the charging station. More information
about DLB conguration can be found in the
‚Conguring DLB in the Charging Station’
chapter on page 17.
The manufacturer is not responsible for
damages resulting from non-compliance
with the above recommendations.
