SETTING THE DESIRED CHARGING CURRENT / POWER without WiFi connection
METRON EV charging stations allow users to set desired charging current / power before being plugged in the electric vehicle. Procedure is simple:
• Press and hold the push button: STATUS LED O-ring switches off immediately.
• After 5 seconds STATUS LED O-ring starts blinking slowly.
• Releasing the push button after a certain number of LED O-ring blinks determines charging current / power as follows:
New charging current / power setting is stored in the memory and it stays the same (even after the power supply is not present anymore)
until the next setting change is performed.
GET STARTED
When no electric vehicle is connected the blue LED STATUS O-ring around station’s black push button(s) glows constantly indicating standby / ready status. When
you plug in the vehicle the STATUS LED O-ring starts blinking slowly what means the vehicle is charging. When your electric vehicle is fully charged the LED O-ring
glows constantly again.
If hardwired or wireless Metron Dynamic Power Control system that offers smart charging is installed the charging power is dynamically controlled in order to not
blow main house fuses; this system is also smartly taking into account the solar / wind / hydro power plant if house has it installed (see chapter “METRON Hardwired
or Wireless Dynamic Power Control” for more info). Users can also via WiFi connect to built-in Metron Charge Control application which offers possibility to change
charging power, delay charging start, monitor real-time charging&house&solar power & energy, activate solar SURPLUS charging and much more (see chapter
“USING THE WiFi METRON Charge Control application” for more info).
If the station is configured in the way authorization is needed for charging start the STATUS LED O-ring shortly blinks every 2 seconds but after successful authorization
(RFID, AutoCharge, OCPP backend, Metron Charge Control app, etc) the STATUS LED O-ring behaves normally.
• Check the EV charging station before use. Do not use the EV charging station if damaged!
• Socket will provide a high voltage (230 / 400 V)!
• Never draw more than maximum specified charging current from the EV charging station!
• Do not use the EV charging station if the socket and plug are wet.
• Only connect undamaged, designated and labelled plugs & cables to the EV charging station.
• Avoid using multiple adapter / power strips as they can lead to overload.
• Don’t unplug during charging process.
• Always operate in the specified order of steps.

REMOTE CHARGE PORT OPEN & PLUG UNLOCK for TESLA electric vehicles
Metron charging stations with built-in charging cables can be equipped with TESLA remote charge port open & plug unlock electronics. Pressing a “2-function” button
on the vehicle Type 2 plug sends a remote-control signal to your TESLA vehicle charge port which then opens. Signal range is usually between 3 and 15 meters. This
feature eliminates user “touching” the smart phone or Tesla central screen in order to open the charge port. Remote-control signal also wakes-up the Tesla vehicle
from sleep - sometimes the button needs to be pressed several times to wake-up the vehicle.
To unplug while still charging or when charging completed press and hold the “2-function” button for a second. The car will unlock the vehicle plug (only if car is
unlocked / owner nearby!) and then you can unplug it. Plug unlock function works even if the charging station is not powered (manually turned off, grid power
outage, etc).
This feature once again eliminates the need for user “touching” the smart phone or Tesla central screen in order to unlock the charging plug from Tesla charge port.

USING THE WiFi METRON Charge Control application (SMART »+« charging stations only)
Smart EV charging stations marked with “+” have a built-in WiFi access point with web server what enables users to connect to it wirelessly by any smart phone, tablet
or laptop PC. As there is a web server inside with preloaded METRON Charge Control application you don’t need to install any additional program / application on
your device because the METRON Charge Control simply runs in your favorite web browser (Google Chrome, Microsoft Edge, Mozilla Firefox…) on any operating
system (Google Android, Apple iOS, Microsoft Windows, Huawei HarmonyOS, Linux…) you have on your smart phone, tablet or laptop PC.
Using the web-based METRON Charge Control application user can:
•Disconnect the station from power, press the “Push Button” and keep it pressed.
•Connect the station to power.
•The blue STATUS LED O-ring starts blinking 2 times.
• After 30 seconds the STATUS LED O-ring will turn-on for 3 seconds and then turn-of.
•Release the “Push Button” and WiFi name (ssid) & password are reset to default values.
To connect to the WiFi METRON Charge Control application you need to do the following:
•
•
•
•
•
Make sure the charging station is energized (connected to power).
Go to WiFi menu in your smart phone, tablet or laptop PC and search for WiFi networks.
Find “METRON Station 1” (default) network and connect to it; enter the WiFi password 12345678 (this is default - it is
recommended that you change it in the METRON Charge Control application).
Scan QR code you find on the station and follow the link (it will open your default web browser and launch the
Metron Charge Control automatically); OR open your favorite web browser and type in the following IP address:
http://192.168.4.4
The METRON Charge Control application will be loaded immediately. Up to 5 users (devices) at a time can be
wirelessly connected to the station and all connected devices will automatically receive all the latest data; for

METRON Hardwired and Wireless Dynamic Power Control
(SMART »+« charging stations only)
Smart “+” marked EV charging stations can be equipped with Hardwired (1 station per main fuse) or Wireless Dynamic Power Control system (up to 150 charging
stations fer main fuse) that is always monitoring the load at house main fuse with electric current sensors and dynamically adjusting (lowering or rising) the charging
current/power of your electric vehicle in the way the main house fuse never gets overloaded (never blows-up). If the house has a solar (or wind/hydro) power plant
installed this system allows higher current/power charging than would be allowed by the main fuse and it also enables the possibility of user activated solar SURPLUS
charging what means the vehicle will be charged only with excess solar power without taking any energy from the grid. METRON Wireless Dynamic Power Control
system is designed to work with 1-phase and 3-phase power systems. To be short, METRON Dynamic Power Control system enables users to charge their electric
vehicle without worrying about the load other household appliances might draw from the in-house grid.
For 1-station Hardwired Dynamic Power Control the installer needs only to place clamp-on current sensors to main house power inlet and solar power plant (if
present). In case of dynamically controlling 2 or more charging stations this can be done wirelessly only as this greatly reduces laying cables and thus cost. For
METRON Wireless Dynamic Power Control all you need is 1 pcs METRON Dynamic EV Charging Unit (model 3FD-3) with clamp-on current sensors. This way up to 150
Metron wall-mounted, floor mounted or even METRON smart portable EV charging stations can be controlled and main fuses with rated currents up to 1000A are
supported.
Note: Wireless signal has an open-air space range of 500m with built-in antenna and up to 2000m with additional antennas on the METRON Dynamic EV Charging
Unit (model 3FD-3). If the system is installed within one house usually no additional antenna is needed.

RCCB is an acronym for Residual Current Circuit Breaker - sometimes it can be called also Earth Leakage Circuit Breaker or Safety Switch. Its purpose is to prevent you
from getting a fatal electric shock if you touch live part, such as a bare copper wire under high voltage. RCCBs offer a level of personal protection that ordinary fuses/-
circuit-breakers cannot provide. RCCB constantly monitors the electric current flowing through one or more circuits which it protects. If it detects electricity flowing
down an unintended path, such as through a person who has touched a live part, the RCCB will switch the circuit off very quickly, significantly reducing the risk of
death or serious injury. Every charging station has integrated Type A 30mA AC + 6mA DC or Type B RCCB what ensures maximum possible level of personal protection
as it protects users from AC, pulsating DC and pure DC leakage currents.
WHAT IS RCCB AND HOW DOES IT WORK?
