Warning: Mortal danger posed by improper installation. There is a risk of injury for persons per-
forming tasks for which they are neither qualified nor have received appropriate training.
• The device may only be installed by personnel which are familiar with the task, have been instructed
with regard to the associated hazards and who possess the necessary qualifications.
• Before installing, all safety requirements must be met.
Choice Of Location
Warning: Risk due to unsuitable environmental conditions / installation locations. Unsuitable ambient
conditions and installation locations may lead to dangerous situations when dealing with electricity.
Please observe the following points when selecting an installation location:
• Do not install in potentially explosive atmospheres (e.g. gas refueling stations).
• Do not install in flood-prone areas.
• Comply with local technical connection requirements and safety rules.
• For ambient conditions, see Chapter “Ambient conditions” on page 7.
• The charging system must be protected from direct exposure to water jets.
• The mounting surface must have sufficient strength to withstand the mechanical stresses. When
mounting on plasterboard walls they must have at least two layers.

Installing The Charger Station On The Wall
For installation on concrete, brick and wood walls, use the included installation hardware. For other sur-
faces, a suitable on-site mounting method must be chosen.
METRON recommends the installation of the charging station at a height (up to the top edge of the en-
closure) of approximately 1.50 meters above the finished floor.
1. Mark the mounting holes
2. Drill the holes in the wall
3. Secure the charging station to the wall by using dowels and screws
Check the charging station for firm and secure fit.

Voltage Supply / Supply Network Connection
Warning: Risk of death by electric shock! Components have voltage applied. Contact with current
conducting parts results in an electric shock, burns or death. When working with the electrical
system, the following points must be observed:
• Disconnect device from voltage
• Secure device from being turned back on
• Ensure that no voltage is applied
• Earth and short-circuit the unit
• Cover neighboring components that are under voltage and secure the danger area
Note the following points when connecting to the power supply:
• Observe the application national/local regulations;
• Ensure a clockwise rotating field for a three-phase connection.
Safeguarding And Personal Protection
Warning: Danger to life by electric shock. Residual current circuit breakers (type B) sensitive to
universal currents may be installed instead of residual current circuit breakers (type A) sensitive to
pulse currents. Depending on the equipment package, the charging stations are fitted with the
required safety equipment
Note the following points when connecting the charging station:
• Each charging station must be connected using a separate residual current circuit breaker (residual
current circuit breaker type A for single-phase versions, residual current circuit breaker type B for
three-phase versions).
• No other circuit may be connected to this residual current circuit breaker
• Design of the on-site circuit breaker
Warning: Fire hazard due to device overload.
Fire hazard due to device overload in case of wrong design of the on-site circuit breaker.
The normal current of the selected circuit breaker must not exceed the specifications on the
nameplate.

13Electrical connection
Electrical connection
Connecting The Supply Line
1. Strip the supply cable over a length of 370 mm and remove the core insulation over a length of 12 mm
2. Connect the cores of the supply cable to the RCCB ①and the earth core to the terminal ②
The protective earth conductor ③must be longer than all other conductors
3. Check that the individual cores are properly connected and that the screws are tightened
4. Turn the reset leaver ④to position 1 to power the system

14 Operation
Warning: Mortal danger posed by improper installation. There is a risk of injury for persons per-
forming tasks for which they are neither qualifies nor have received appropriate training.
Operation
Warning: Risk of injury
There is a risk of injury due to damage to the charging system.
If it appears that, the charging system cannot be operated safely:
• Take the charging system out of service.
• Determine and eliminate any faults / malfunctions.
• Contact your electrician, local dealer or direct factory help
Dynamic Power Control
This is an advanced function that protects the main
household fuse, which is installed on the phase
that your electric vehicle is using for charging. For
this to function you have to install a current sensor
on the line (L1, L2 or L3) that comes from the main
household fuse and then connect this sensor to
the charging station. The maximum length of the
current sensor connecting cable is 40 m. We rec-
ommend that you use shielded 8 core UTP cable
and use 4 wires as one wire.
The function of dynamic power control has three
groups of settings, which are set with the push but-
ton (see chapter “How to set the charging station
on page 15):
Caution: When the charging station receives power supply
(connection to the grid) the LED blinks 5 times.

15Operation
Operation
How To Set The Charging Station Part 1
1. Press and hold the push button (LED switches off
immediately)
2. After 5 seconds LED starts blinking slowly
3. Releasing the push button after a certain number
of blinks determines the setting (see example on
page 17)
Important: If after 5 or 8 blinks (depending on the charging station) you do not release the push
button for another 30 seconds, the system will take you to the next setting which enables you to set
the main household fuse type. The setting begins automatically when the LED starts to blink again.

2nd Group – Main Household Fuse Type
With this setting, you set the amperage of the main household fuse on which your car will be connected.
For more information on the type of the main household fuse, please contact your grid operator. The
default value is set to 16 A.
Number of blinks From 1 to 40 (each blink signals 1 Ampere)
Fuse type From 1 to 40 A
Caution: If after 40 blinks you do not release the push button for another 30 seconds, the system
will take you to the next setting which enables you to set the on board charger response time.
The setting begins automatically when the LED starts to blink again.
3rd Group – On-board Charger Response Time
This setting defines the on-board charger reaction time. Most of the chargers can change the current
every 2 seconds. This setting does not need to be changed since the default value is set to 2 seconds.
Warning: Risk of serious damage if done incorrectly. Performed only by expert who is qualified
and have received appropriate training.
How To Set The Charging Station Part 2
Since these settings are in consecutive order, the first setting you need to perform is the “On-board char-
ger response time” (not necessary). Once you do that, you have to start again to set the “Main household
fuse type” and at the end, you can set the desired “Charging current” (See example on the next page).

17Operation
Operation
1. Press and hold the push button (LED switches off immediately);
2. After steps:
• 5 LED blinks
• 30 seconds
• 40 blinks
• 30 seconds, you will enter in the 3rd Group;
3. Releasing the push button after 5th blink determines the setting.
STEP 2
Next is main household fuse type.
Example 1:
Let say we want the following specifications for our charging station:
• Current Setting = 16 A
• Main household fuse type = 32 A
• On-board charger response time = 5 seconds
STEP 1
First, you need to set the on-board charger response time.
1. Press and hold the push button (LED switches off immediately);
2. After steps:
• 5 LED blinks
• 30 seconds, you will enter in the 2rd Group;
3. Releasing the push button after 32nd blink determines the setting.

18 Operation
Operation
STEP 3
Next is main household fuse type.
1. Press and hold the push button (LED switches off immediately);
2. Releasing the push button after 5th blink determines the setting.
Example 2:
For this example, we want the following specifications for our charging station:
• Current Setting = 20 A
• Main household fuse type = 25 A
• On-board charger response time = 2 seconds
In this case we can skip the setting for “On-board charger response time” because the default setting
is already set to 2 seconds (unless you have changed it with previous setting).
STEP 1
Set the main household fuse type.
1. Press and hold the push button (LED switches off immediately)
2. After steps:
• 5 LED blinks
• 30 seconds, you will enter in the 2nd Group;
3. Releasing the push button after 25th blink determines the setting.
