Operation
Start-up
Connecting the charger to the mains (see figure A)
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the charger. Chargers marked 230 V can
also be operated at 220 V.
Plug the device connector (3) of the power cable into the
device socket (2) on the charger.
Connect the power cable (country-specific) to the mains.
Charging the removed battery (see figure B)
Switch the battery off and remove it from its holder on the
eBike. When doing so, read and observe the operating in-
structions of the battery.
Ensure the battery is placed on clean surfaces only.
u
Avoid getting dirt, e.g. sand or soil, in the charging socket
and contacts in particular.

There is a risk of fire due to the charger heating up
u
during charging. Ensure the battery on the bike is
V~ 220 ... 240
completely dry and placed on a fireproof surface be-
Hz 50 ... 60
fore charging. If this is not possible, remove the battery
V= 36
from the holder and charge it in a more suitable location.

Charging process
h 3.5 The charging process begins as soon as the charger is con-
nected to the battery or charging socket on the bike and to
the mains.
°C 0 to 40
Note: The charging process is only possible when the tem-
°C 10 to 40
perature of the eBike battery is within the permitted char-
kg 0.7
ging temperature range.
IP40
Note: The drive unit is deactivated during the charging pro-
cess.
The battery can be charged with and without the on-board
computer. When charging without the on-board computer,
the charging procedure can be observed on the battery
charge indicator.
When the on-board computer is connected, a charging noti-
fication appears on the display.
The state of charge is displayed by the battery charge indic-
ator (8) on the battery and by the bars on the on-board com-
puter.
The LEDs on the battery charge indicator (8) flash during the
charging process. Each solid illuminated LED represents ap-
proximately 20 % of the charging capacity. The flashing LED
indicates the next 20 % currently charging.
Once the eBike battery is fully charged, the LEDs go out im-
mediately and the on-board computer is switched off. The
charging process is terminated. The state of charge can be
displayed for 5 seconds by pressing the on/off button (9) on
the eBike battery.
Disconnect the charger from the mains and the battery from
the charger.
When the battery is disconnected from the charger, the bat-
tery is automatically switched off.
Note: If you have charged the battery on the bike, carefully
close the charging socket (6) with the cover (7) after char-
ging, so that no dirt or water can get in.
If the charger is not disconnected from the battery after
charging, after a few hours the charger will switch itself back
on, check the state of charge of the battery and begin the
charging procedure again if necessary.
