PROCEDURE IN CASE OF IRREGULARITY OR
INTERFERENCE AT OPERATION
In the event of irregularities or interference in the operation of the
device, immediately stop using the charging station and inform the
charging station operator of the situation by phone number located on
the housing or other place.
DESIGN CONSIDERATIONS
Special care has been put into selection of components and materials
and their compliance to requirements set in standards, technical
directives and rules of good practice.
The internal wiring was carefully designed, and the propriety of whole
assembly thoroughly evaluated. Basic design considerations include
voltage, insulating materials, time under voltage stress and degree of
pollution at the location. Creepage distances, clearance between circuits
and spacing to metal enclosures are important requirements for
insulation coordination. Thus, calculation and measurement of clearance
and creepage distances, in accordance with requirements, are one of the
significant parts in design of our products.
They are dimensioned to withstand the required impulse withstand
voltage and to withstand the long-term continuous operation. A
charging station operates with an RCD device, which is designed to
protect against the risks of electrocution and in addition offers
protection against fire caused by earth faults. It is a sensitive safety

5 | 18
Etrel Inch Lite | User Manual
|
device that switches off electricity automatically if there is a fault.
The ingress protection class of IP54 proves, that the enclosure of the
charging station is protecting the internals against ingress of solid
objects, permits only limited ingress of dust and is protected against
water splashes from all directions. Impact protection, of at least IK10
states, that the charging station can withstand impacts, equivalent to
5 kg dropped from height of 40 cm. As required, tests for the IK class
were performed before testing of IP class.
FIRE SAFETY MEASURES
At the location of car charging, the fire hazards and thus the threats are
increased during the process of charging. The overall design of our
products is made on the basis assumption that the fault could occur on
any element of the system. Either in the electrical wiring of power
supply, in wiring or inside of the charging station, or in the car.
The enclosure and the assembly design are made in such a way that the
contact of the user to hazardous parts is not possible. In the event of
fire, metal enclosure would constrain a fire and would not allow the
propagation outside of the enclosure. Regarding the fire safety in all
possible cases of installation, that are out of control of our company,
several recommendations are listed:
•The charger must be installed outside the hazardous area.
•The installation of the charging station can be performed only by
professional electrician and must comply with the installation
manual and local installation rules.
•Ensure that there is enough space to manoeuvre vehicles into
their designated charging areas and that in event of fire the
escape and rescue routes are not obstructed.
•No flammable or combustible material should be stored within
the charging area.
•Provision of suitable portable fire extinguisher at the location of
the charging station is proposed.
•When the charging station without integral RCD device is
installed, the proper RCD device should be installed in the main
electrical cabinet.
FIREFIGHTING MEASURES
In case of fire please follow these steps:
•In the event of a fire, immediately stop using the charging
station and call the appropriate services (fire brigade).

6 | 18
Etrel Inch Lite | User Manual
|
•If possible, disconnect the station from the power supply by
pressing the fire protection switch (if present) or another switch
responsible for cutting off the power supply to the station.
•Retreat from fire area.
•Extinguishing should be carried out with extinguishers intended
for extinguishing electrical devices up to 1000 V.
Do not extinguish live electrical installations and devices with water!
ENVIRONMENTAL SAFETY MEASURES
When implementing protection measures, environmental protection
must also be observed. For this reason, special care has been put into
selection of the components and their compliance with the Directive on
the restriction of the use of certain hazardous substances in electrical
and electronic equipment (RoHS). This directive restricts use of
hazardous materials in the manufacture of various types of electronic
and electrical equipment.
The substances banned under RoHS are heavy metals, lead (Pb),
mercury (Hg), cadmium (Cd), hexavalent chromium (CrVI),
polybrominated biphenyls (PBB), polybrominated diphenyl ethers
(PBDE), and four different phthalates (DEHP, BBP, DBP, DIBP). The
restricted materials are hazardous to the environment and pollute
landfills and are dangerous in terms of occupational exposure during
manufacturing and recycling.
Another example of use of environmentally friendly materials in our
products is compliance to REACH, which is a regulation of the European
Union, adopted to improve the protection of human health and the
environment from the risks that can be posed by chemicals. REACH
regulation also promotes alternative methods for the hazard assessment
of substances in order to reduce the number of tests on
animals. Packaging of our products is environmentally friendly and
materials degradable.
CORRECT DISPOSAL OF THIS PRODUCT (INFORMATION

Overload and short-circuit protection is ensured with use of suitable MCB. Additional surge protective device could
be required by national legislation. Protective devices can be installed either in charger, or in an installation
upstream. Coordination and selectivity of protection devices with upstream devices should be ensured, so that
only the protection device, the closest to the fault, operates.
Electrical burns and other injuries are prevented with use of appropriate protective devices, properly designed
insulation and prevention of arcs.
To prevent leakage currents, the suitable RCD protection device is used either in charging station, or in an
installation. Each socket must be protected by individual RCD. The power supply was selected to have a negligible
leakage current.
The use of quality housing with use of additional structural supports ensures high resistance on mechanical stress.
The proper installation of mounting anchor ensures that the charger is rigidly supported and can not turn over.
Our charging stations are tested to determine the IK code (degree of protection provided by enclosure) in
combination with tests to determine IP code (ingress protection).
The use of quality housing with use of sealing foam and filters ensures high resistance to ingress of particles. Our
charging stations are tested to determine the IP code (ingress protection) in combination with tests to determine IK
code (degree of protection provided by enclosure).
The only moving part representing the hazard is the opening and closing of the doors. The doors should be closed
only if there is nothing blocking them (either mechanical object, or human hand). This risk is also mitigated with the
explanation in the user and installation manual.
There is a possibility that sharp edges occur during the production process during the cutting and assembly of the
housing. For this reason, possible sharp edges that could harm a person, were identified and are grinded away
after the assembly. The wires are also protected so that they do not come into contact with the remaining sharp
edges. Proper processing, finishing and coloring procedures of the surfaces ensure high quality product.
The components are dimensioned in such a way that they cannot cause a charge that would be hazardous to
human health. In case of vehicle malfunction, the possible hazard of stored charge is mitigated by the use of RCD.
The major concern with vibrations is the loosening of electrical connections. For this reason, special care is made
during the production process to use the optimum torque and tightening sequence for fasteners with use of tools
with settable screwing torque.
Moving parts, especially where
there may be variations in the
rotational speed of parts
The tolerances of parts are high enough to not represent a problem during the manufacturing process. In addition,
the manufacturing instructions are covering all possible improper fittings of connectors and other components. All
charging stations are put on the testing line after assembly where possible improper fitting would be identified.
Basic protection is provided with selection of appropriate insulation of all components and in addition live parts
are not accessible during charging. Fault protection is achieved with earthing of all exposed conductive parts and
with automatic disconnection of the supply in case of a fault. Additional protection is also provided, with use of
high sensitivity RCD's.
The use of suitable switching and protective devices ensures that possible arcs are extinguished quickly and
without causing damage.

Charging station complies to all requirements of the standards of the EN 61851 family, to all parts relevant to AC
conductive charging and is compliant to all versions, current and old. This family of standards covers requirements
for charging stations from all aspects, however some details are covered in other standards, as listed in this table.
Charger construction ensures that break-down during operation is not possible in normal conditions. This would
be possible only with high enough external force, e.g. vehicle collision. For this reason the recommendation for
public charging stations is to use protective bollards.

Our charging stations are subjected to tests and certification to ensure safe operation from the view of
electromagnetic compatibility (EMC) and electromagnetic interference (EMI). The compliance with EMC limits
ensures that the charging station is not emmiting electromagnetic fields that could affect other devices and
compliance with EMI limits ensures immunity of the charging station and safe operation when subjected to
electromagnetic fields that could occur in the vicinity of the charging station. In addition the charging station are
tested and certified in accordance with radio equipment directive (RED) when applicable. The certification proves
that the electromagnetic fields generated by the charger are limited to the extend neccessary for the operation.
In the event of fire, metal enclosure would constrain a fire and would not allow the propagation outside of the
enclosure. Used materials are resistant to ignition and spread of fire. External parts of insulating material and
insulating parts are resistant to abnormal heat and to fire. Installed RCD device protects against fire aswell.
Using the equipment beyond its environmental specifications may give rise to temperature hazard. This is well
mitigated with selection of appropriate materials.
Charging station design was made in accordance with all major international standards that are considered in
scope of e-mobility and is designed and constructed to be safe and reliable to prevent hazards arising and
withstand normal use in foreseeable environmental conditions, misuse and errors in logic.

High humidity inside of charging station can damage the electrical components. To avoid the risk, during the
installation, the base of charging station should be covered with polyurethane foam or similar filling. The charging
station has vents to enable natural ventilation. The finishing of the external surfaces offers high protection against
environmental conditions and prevents the corrosion and rust. Additional measures can be the addition of silica
gel or similar hygroscopic material. Also, the option to install a small heater preventing condensation inside of
charger is provided.

Functional safety and reliability
The charging station does not connect EV to the electrical grid under full load. Firstly, the connection to the electric
vehicle is made only after security checks and mitigation between charger and vehicle. The charging current is then
gradually increased to full allowed current. Thusly, the connection of the load does not represent a "spike" in
consumed power. In case of interruption the charging station shuts down gracefully to not damage any
components. The proper earthing also promotes the quick discharge of possible built-up charge.
After the starting of charging process no additional inputs are needed as charging stations are designed to be able
to charge without supervision. The implemented protection measures would operate independently of human
presence.

4 REGULAR MAINTENANCE
Etrel charging station does not require any periodic maintenance.
However, it is recommended to perform a visual check and test of the
protection elements once per year.
Detailed descriptions of security checks and their intervals are included
in the service manual.
RESET AND TEST THE PROTECTION ELEMENTS
OVERCURRENT PROTECTION
Check the overcurrent protection (if installed) once a year for any visible
damages on the surface. If the overcurrent protection is tripped and the
switches cannot return to the active position something is wrong with
the protection and needs to be changed by maintenance crew.
SURGE AND OVERVOLTAGE PROTECTION
Check the surge and overvoltage protection (if installed) once a year for
any visible damages on the surface. If the surge and overvoltage
protection is tripped it needs to be changed by maintenance crew.
RCD
The regulations require that residual current protective device (RCD) is
tested regularly, and an audit log should also be kept. The test button on
the RCD unit allows user to verify the correct operation of the device by
passing a small current through the RCD unit. This simulates a fault by
creating an imbalance in the sense coil. If the RCD does not trip when
this button is pressed, then the device must be replaced by licensed
electrician. The device must be changed also when the RCD was tripped
but the switch cannot be moved back into active position. RCD testing
must be completed every three months and documented.

5 TROUBLESHOOTING
Errors dangerous to device users:
Dangerous voltage present on enclosure or device under fire. In this case
the device should be turned off immediately. Switch off device power
supply of device in the distribution board from where device is supplied
and not on device itself. Do not touch device. If vehicle is connected at
that moment, disconnect plug from the vehicle and not from the
charging station, but only after the power supply was switched off. In
the case of fire use fire extinguisher appropriate for electrical fire.
Faults occurred because of external conditions:
Undervoltage, overvoltage, short and long power supply outages or
wrong vehicle behaviour. In these cases, no action is needed to re-
establish normal operating conditions. Once fault is gone, normal
operation conditions will be established automatically. If temporary fault
was caused by vehicle, user will have to reinitiate charging session.
Device hardware failure preventing normal operation:
Example: Broken socket, electronics failure. If after restart device does
not start normally, contact supplier support.
Charging station software failure:
Check that latest version of firmware is running on the charging station.
If the latest version is installed and problem persist, then check if
problem is caused by the charged vehicle. To check this, the charging
could be tried on another charging station. If problem is not in the
vehicle send diagnostic logs to the supplier.
ACCESS TO THE MAINTENANCE AREA
Etrel INCH LITE charging station provides quick access to the side
maintenance area to execute basic troubleshooting and to reset the
charging station in case there are some problems.
Side maintenance area is protected by the side maintenance doors.
Depending on the type of Etrel INCH LITE charging station, two different
doors are available. One with the regular key lock and one with hex
screw (2.5 mm). To access the area, either key or a hex screwdriver is
needed.

There is a sticker on the inside of maintenance doors, with technical
information including basic charging station information, model type
and serial number. When support is contacted it is important that the
charging station model type is known so the support can quickly help
solve the issue.
RESETING THE CHARGING STATION
Charging station can be reset by opening the side maintenance doors
and pressing the button inside the maintenance opening.
After holding the button for 4 s, the charging station will respond with
the beep after which the options on the screen to check the IP address
of the station or to reset the station will be presented. Basic reset and
factory reset, which will restore charging station’s factory settings
(username, password, default IP and other settings) can be made.
