CONNECTION TO WEB INTERFACE
Users can connect to the charging station web interface using the
charging station IP address. Default IP address can be found on the
information sticker on the inner part of the maintenance doors. IP of
the charging station can be manually changed. If you did this and
forgot the new created IP you can always revert back to the default
IP by resetting the charging station.
When IP address is written in the internet browser and the computer
is in the same local network you will be connected to the web
interface.
To determine if your computer is in the same network as charging
station ping the station using the CMD command ping with the IP of
the station. You can change computer network in the network
settings.
To ping the station connect to Command Prompt by searching for it
in windows search functionality.

4 RESETING THE CHARGING STATION
Charging station can be either soft or hard reset. This can be done by
opening the side maintenance doors either with key or hex
screwdriver depending on the maintenance door type and pressing
the button inside the maintenance opening.
If you hold the button from 3 s to 5 s the charging station will go
through the soft reset, which can be useful if you experience
problems with the operation of charger. If the problem is not serious
charging station may work normally after the soft reset.
Holding the button from 10 s to 15 s will activate the hard reset that
will revert all the charging station settings to the default ones
(username and password of the web interface, station’s IP and other
settings).

5 RESET AND TEST THE PROTECTION
ELEMENTS
RCD
To ensure that the RCD (if installed) is working properly RCD should
be tested, by pressing the ‘’Test’’ button at least once per month. By
doing this appropriate operation of RCD is guaranteed. If this is not

done the protected device can be dangerous to users and potential
malfunction can be life-threatening.
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. You have to change the device also when the fid was
tripped but you can’t move the switch back into active position. To
change the RCD please call the support number.
Figure 8: RCD test button
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 can’t returned to the active position
something is wrong with the protection and needs to be changed by
maintenance crew.
6 UPGRADING THE CHARGING STATION
Multiple elements in the charging station can be either changed or
upgraded, if for example owner wants additional functionalities
available.
CONNECTION ELEMENT
Charging station has space to include one protection element inside:
overcurrent protection, RCD protection or certified MID meter, used
to check the energy measurements. During the operation owners can
see that different protection is needed or that MID meter should be
installed and the protection elements can be included inside the
electrical cabinet.

FAN
Basic model of the Etrel Inch charging station comes without the fan.
Fan unit can be installed later if it is determined that is needed to
improve the charging station operation.
COMMUNICATION MODULE
Basic model of the charging station comes with the ethernet modul
for the communication. Owners can upgrade the charging station so
that communication can be established using PLC, GSM or through
Wi-Fi.
CABLE LOCKING MECHANISM
Cable locking mechanism is meant for public station to protect the
charging cable from theft. It is normally not instelled in the private
stations. If owner needs cable locking mechanism installed it can be
added on the request.
