Always change out the mains adapters in a dry place.

The adapters are connected and disconnected via the
JUICE CONNECTOR safety connection:
1 JUICE CONNECTOR safety connector. (Connects to
the JUICE BOOSTER 2)
2 Plug and press together until an audible click is heard.
Important: Ensure that you hear and feel the connection
snap into place!
3 Mechanical guides only allow connection in the correct
position (orange dots provide orientation for correct
alignment).
4 Disconnect the connectors by pulling back the retain-
ing ring on the JUICE CONNECTOR safety coupling. This
safety coupling is part of the mains adapter.
5 Protective end caps (always fit the caps in place when
the device is not in use, as they protect against ingress of
dust, moisture and other harmful substances). The JUICE
CONNECTOR is only watertight when fully plugged in.
Charging from domestic or industrial
power outlets
1 Select the fitting mains adaptor.
2 Connect the JUICE CONNECTOR of the JUICE
BOOSTER 2 to the JUICE CONNECTOR of the mains
adapter, as described above.
3 Plug the mains connector into the power source socket
All the LEDs flash yellow while the BOOSTER 2
performs its self-test.
4 The device is ready for operation within approx. 3
seconds.
The detected charging current intensity (AM-
PERE) is displayed in green.
The set operating mode (MODE) is displayed for
30 seconds by flashing yellow LED.

If the ampere charge value and the operating
mode are in the same position, the LEDs flash
yellow and green alternately.
5 Check, if the charge current intensity is correct.
6 Note: The charge intensity can be reduced within the
first 30 seconds after connecting the BOOSTER 2 to the
vehicle by pressing the SELECT button.
7 Plug the vehicle-end coupling into the vehicle's charg-
ing connection socket.
8 The charging process begins automatically.
The sequential flashing orange LEDs indicate
that charging is in progress.
A green LED continues to display the set charge intensity.
9 The charge process ends.
If only the green LED displaying the charge
intensity is lit, the vehicle has properly ended the
charge process.
If charging at first fails to start automatically, it's possible
that a setting in the vehicle has scheduled charging for a
certain specific time of day.
Changing the charge intensity (AMPERE)
Press the SELECT button (before plugging the vehi-
·
cle-end connector into the vehicle charging socket, or
within 30 seconds after plugging it in).
The green LED begins to flash, indicating
that the device is ready to change the charge
intensity.
Press the SELECT button as many times as necessary
until the LED is at the desired amperage.
Pressing the button again after position 6 amperes
·
causes the LED to jump back to the maximum value
defined by the given adapter in use.
Reducing the charge intensity is always recommended
·
for old installations and continuous operation. This may
also be necessary if multiple e-cars are being charged at
outlets that share fuses, or where the outlets are fused
for and specifically state lower amperage values.
For safety reasons, the charge intensity cannot be
·
increased beyond the charge intensity determined by
the JUICE BOOSTER 2.
The selected setting will be saved automatically after
·
approx. 5 seconds.
