Voltage Drop
The maximum allowable voltage drop for an installation can vary from country to country. Typically,
the requirement is to keep the voltage drop below 4% (or sometimes below 5%). The length of the
conductors, their material, and the charging current are important factors in determining the
appropriate cross-section of cables. However, it's important to note that voltage drop can also occur
in other components and devices. Therefore, it is advisable to consider some additional reserve when
selecting the cross-section of cables to account for these factors.

Continuity Test for Earthing Conductor
To ensure proper safety measures, it is important to perform a continuity measurement on the
protective conductors, including those in the main and additional equipotential. This measurement
involves checking the connection between the PE terminal of the charging station's socket and the
inlet PE conductor. If the charging station is equipped with a cable, the measurement should be
made between the PE conductor of the cable plug and the inlet PE conductor.
Before conducting these measurements, it is crucial to switch off the charging station or the main
power supply to eliminate any potential hazards.
For accurate results, the continuity measurement should be performed with a current equal to or
greater than 200 mA. The open circuit test voltage should range between 4 and 24V, whether AC or
DC. The measuring range should cover values from 0.2 Ω to 2 Ω, with a maximum permissible
operating uncertainty of +- 30%. Digital equipment used for measurement should have a resolution
of at least 0.1 Ω.
Using an instrument with the capability to measure at higher currents than 200 mA can enhance the
accuracy of the measurement. The figure below illustrates the method of conducting the continuity
measurement.

6
Figure 2: Continuity Measurement
To meet the continuity requirement, the connection resistance should not exceed 2 Ω.

ELECTRICAL INSTALLATION REQUIREMENTS
Earthing System
The earthing system in an electrical installation serves a crucial role in ensuring electrical safety and
protecting against potential hazards. It primarily focuses on mitigating risks associated with static
buildup and safeguarding against power surges induced by lightning strikes or switching events.
PublicBox is designed to be compatible with multiple earthing systems, including TN-C-S, TN-S, and
TT. These systems provide reliable grounding solutions that are widely adopted and recognized for
their effectiveness in maintaining a safe electrical environment. By supporting these earthing
systems, PublicBox ensures enhanced safety and compatibility for a variety of installation scenarios.

Figure 5: TT
Electrical Cables
Power Supply: The electrical infrastructure must be able to support the charging station's
power output.
Cable Requirements: The charging station requires a 5-wire, 3-phase, neutral wire + ground
cable. The cable must have a minimum size of 16 mm2(6 AWG) and be capable of handling a
maximum continuous current of 64A. And communication ETH cable (2 x ETH cable, directly
from the switch or 1 x ETH cable, which is connected with a Y splitter on the switch side and
split with a Y splitter on the side of the charging station).
Grounding: Proper grounding is essential for the safe operation of the charging station.
Ensure that the charging station is properly grounded and that all electrical connections are
secure.
Circuit Breaker: The charging station must be protected by a properly rated circuit breaker.
The circuit breaker should be installed in accordance with local electrical codes and
regulations.
Electrical Safety: The charging station must be installed by a licensed electrician or certified
installer in accordance with local electrical codes and regulations. Do not attempt to modify
or repair the charging station's electrical components unless you are qualified to do so.
Mounting with Anchor
To prepare for the installation of the charger, follow the steps below:
1. To install the PublicBox on the ground, we recommend using an anchor. The anchor needs to
be concreted into the ground. PublicBox then mounts the four screws on the anchor. For pre-
installation it’s important to prepare the spot for the charger. If you are using an anchor,
prepare the hole and pour concrete to secure the anchor into the ground. Allow enough
space for the cables to pass through the concrete and anchor. Make sure to leave
approximately 1 meter of space around the anchor to allow for installation and maintenance
purposes.
2. Ensure that the anchor is installed on a solid and stable surface, and that it is securely fixed
to the ground.
3. Make sure that the anchor is leveled so the PublicBox has a leveled surface.
4. Cables come from the ground through the hole on the bottom of the PublicBox.

Network
For the PublicBox Platinum to be connected to a network, you will need to prepare an Ethernet
cable. The Ethernet cable should be of sufficient length to reach the desired location of the charging
station and should be properly rated for outdoor use if the charging station will be installed
outdoors. It is recommended to use a shielded Ethernet cable to minimize the risk of interference.
When running the Ethernet cable, care should be taken to avoid sharp bends or kinks, as this can
cause damage to the cable and affect the network connection. Additionally, the Ethernet cable
should be kept away from sources of electromagnetic interference, such as power cables or electrical
equipment, to ensure a stable network connection.
Overall, it is important to ensure that the Ethernet cable used for network connection meets the
necessary requirements for length, rating, and shielding, and that it is installed properly to ensure
reliable network connectivity for the charging station.
DHCP or Static IP
By default, the PublicBox Platinum is set to use DHCP for obtaining an IP address from the network.
However, if the customer wishes to use a static IP address for the charging station, they should
prepare a working IP address in advance. This will allow for a quick and smooth installation process.
When configuring a static IP address for the charging station, it is important to ensure that the IP
address, subnet mask, default gateway, and DNS server settings are set correctly. The customer
should obtain these network settings from their network administrator or Internet Service Provider
(ISP) to ensure that the charging station is properly configured and can communicate with other
devices on the network.
Once the static IP address has been obtained and the network settings have been configured, the
customer can easily set the charging station to use the static IP address during installation. This can
be done through the charging station's configuration menu or via a web browser interface (check
configuration manual).

13
Load Management
For DLM to work you will need internet connection to charger and Energy Meter.
To enable Dynamic Load Management (DLM) functionality on your charging stations, they must be
daisy-chained together using an Ethernet cable. This allows them to communicate with each other
and share information about the available power supply, which enables them to adjust their charging
rates accordingly to prevent overloading the electrical infrastructure.
Daisy-chaining is a method of connecting multiple charging stations in a series using a single Ethernet
cable. In this configuration, the first charging station is connected to the Ethernet switch or router via
the ETH0 port, and then the cable runs from the ETH1 port of the first charging station to the ETH0
port of the next charging station, and so on.
Figure 9: Daisy Chaining
When planning the installation of multiple charging stations, it is important to consider the space
required for the Ethernet cable that will be used for daisy-chaining, the cable will run between the
chargers. The length of the Ethernet cable required will depend on the number of charging stations
connected to and the distance between them. For outdoor installations, it is recommended to use a
shielded Ethernet cable and to avoid sharp bends or kinks when running the cable to prevent
damage.
For Energy Meter connection you need:
oEthernet connection: Energy meter must be connected to the ethernet cable, the
communication between charger and meter takes place via IP address. So it’s important to
prepare an ethernet cable to the energy meter device. Once the charging stations are
properly daisy-chained and connected to the energy meter via IP, the DLM system can be
configured and activated to allow for optimal charging rates and efficient use of the available
power supply. We recommend consulting with a qualified electrician or installer to ensure

14
that the installation is done safely and in compliance with local electrical codes and
regulations.
oPower: To prepare for energy meter, you will need to ensure that there is adequate space in
your electrical cabinet. If space is limited, an additional electrical cabinet can be installed.
The energy meter should be mounted in a way that allows for the three phases to run
through it. Additionally, you will need to connect a neutral wire to the energy meter. Please
note that the energy meter should be mounted before all other consumers.
