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 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).
- 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 ABOUT WEEE DIRECTIVE)

Energy supply|
YES
| 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.
Stored charges|
YES
| 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.
Arcs|
YES
| The use of suitable switching and protective devices ensures that possible
arcs are extinguished quickly and without causing damage.
Electric shock|
YES
| 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.
Burns|
YES
| Electrical burns and other injuries are prevented with use of appropriate
protective devices, properly designed insulation and prevention of arcs.
Protection against mechanical hazards
Instability|
YES
| 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 1K code (degree of
protection provided by enclosure) in combination with tests to determine IP
code (ingress protection).| EN 62262:2002, EN 60529:1991
Break-down during operation|
YES
| 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.
Ingress|
YES
| 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).
Falling or ejected objects|
NO
|
/
|
/
Sharp edges or corners and inadequate surfaces|
YES
| 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.| Directive
LVD 2006/95/ED (through April 19, 2016) and Directive 2015/30/EU (from April
20, 2016)
Moving parts, especially where there may be variations in the rotational speed
of parts|
YES
| 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.| IEC 60335
Vibration|
YES
| 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.| IEC 60335
Improper fitting of parts|
YES
| 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.| IEC 60335

Hazards arising from electric, magnetic, and electromagnetic fields, other ionizing and nonionizing radiation|
YES
| 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.| EMC Directive 2004/108/EC (through April 19,
2016) and EMC Directive 2014/30/EU (from April 20, 2016), EN 61000-6-1:2007,

Fire|
YES
| 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 as well.| EN 61439-1:2011, HD 60364-4-42:2011
Temperature|
YES
| Using the equipment beyond its environmental specifications may give rise to
temperature hazard. This is well mitigated with selection of appropriate
materials.| EN 61439-1:2011, IEC TS 61439-7:2018, HD 60364-4-42:2011, EN
60068-1:2014
Humidity|
YES
| 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.| EN
60068-1:2014

YES
| 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.| EN 61851
Connection to and interruption from power supply|
YES
| 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.| EN 61851

Before starting the station, it is absolutely necessary to read this manual and the technical specification of the device.
When the charging station is power up for the first time it can take several minutes for station to get ready to start using it to charge EV. Charging station is powered up automatically when it is connected to the electricity. In the table below, all possible events that can occur at the power up of the station are listed with the procedure what to do in case something is wrong.
STATUS LIGHT
| NORMAL OPERATION| PROBLEM|
SOLUTION
---|---|---|---
Fast blinking green light| Charging station’s backup batteries are charging.
At the first power, up it can take up to 10 min. If backup battery is full
green light will blink slowly. | If the light is blinking fast more than 10
min there might be a problem with the backup battery.| Inform the support
about the status of the charging station.
Slowly blinking green light| Heating system is trying to heat the electronics
before it is turned ON.| If the green light is blinking slowly for more than
10 minutes, there might be a problem with the hardware.| Support should be
called.
Steady glowing green light| Charging station is ready to be used.| /| /
No lights| /| If charging station is not responding after it is powered up,
something might be wrong with connection.| Check the protection elements if
either RCD or overcurrent protection has been tripped. Activate the
protection.
If nothing helps call the support or installer.
Green light is blinking | Charging station is ready to be used.| Charging
station is unresponsive.| Try resetting the charging station. If the problem
repeats there might be a problem with the software. Support should be called.
FIRST CHARGING SESSION
CHECK WHETHER THE CHARGING STATION IS WORKING PROPERLY AND SETTING OF MAXIMAL CHARGING CURRENT
- When the charging station has either overcurrent or RCD protection installed, check whether the protection element is in ON position.
- Connect charging station to the power supply in the electrical cabinet. Installation feeder should be turned on.
- The default value is 16 A and it can be set in range of 6 A to 32 A. Information of the current value is obtained with short press on the key. Number of short beeps represents information of set maximal charging current (number of beeps x 2 A).
- Settings can be accessed with key press for more than 5 s. After that, a long beep is a notification that the settings can be changed. Each short press on the key increments the maximal charging current by 2 A, from minimal value of 6 A. E.g., to set 24 A, the key should be pressed 9 times.
- To save the settings, press the key for more than 5 s. Long beep is a confirmation that settings were saved, two short beeps are a warning that settings were not saved.
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 reestablish 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.
Figure 6: Doors with keylock Figure 7: Doors with hex screw
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.
