Enabling the charging process
After a successful self-test, press the button (1) to set the protection unit to ready and enable the charging process. The LED in the protection unit symbol (2) lights up green.
Ending the charging process
If you want to interrupt the high-voltage battery charging process before charging is completed, the charging process must be interrupted or ended on the vehicle
Checking the Ground Fault Circuit (GFI) of the 110 Volt outlet
The GFI should be checked once a month. Carry out this procedure with the charging cable connected to the 110 Volt outlet and the vehicle. The charging process has to be deactivated:
x Press the test button (3) on the control unit of the charging cable for at about 3 seconds.
x If the test was successful, the warning lights (1) and (2) will light up. Should these warning lights not light up or other lights should light up or flash, an error occurred while testing.
x After a successful test and if error occurred, you can start the charging process by pressing the rest button (6) for at least 3 seconds.

Temperature monitoring
During the charging process the charging cable can become slightly warmer. This is normal and no cause for concern
If the control unit or the charging cable becomes too hot, the charging current will automatically be reduced If the control unit or the charging cable continues to get hot even at the lowest charging current, the protection unit will be switched off, and will remain switched off until it has cooled down sufficiently.
If no other sources of heat, such as direct sunlight, can be identified as relevant, have the outlet checked by properly qualified and trained experts.
Charging cable for charging at charging stations (if equipped)
Keep the charging cable for charging at a charging station safely in its bag in the luggage compart-ment. Follow the operating manual for the charging station. Before using the charging cable, read the procedure for charging with alternating current
WARNING
Charging the high-voltage battery improperly, using improper or damaged outlets and charg-ing cables, improper handling of the high-voltage battery or failure to follow safe charging procedures can cause short circuits, electric shock, explosions, fire, burns, injuries and death.
x Always connect the charging cable to a properly functioning 110 Volt Ground Fault Circuit (GFI) wall outlet. The outlet must be properly protected from water, moisture and other fluids.
x Always check the fuse protection of the GFI outlet before connecting the charging cable.
x Never connect the charging cable to a conventional power outlet, regardless of whether the outlet is protected or not.
x Never use the charging cable with an extension cord of any kind.
x Never let plugs or connectors come into contact with water, moisture, or any other fluids.
x Never use any charging cable if it is damaged and never use the charging cable with a damaged GFI outlet.
x Never attempt to alter or repair cables or other electrical components.
x Never let anybody stay in the vehicle while the high-voltage battery is charging.
x Never do any kind of work on the outside or inside of the vehicle while the high-voltage battery is charging.
x Always disconnect the charging cable completely from the vehicle before starting the motor.
WARNING
If you are not familiar with the outlet or the electrical installation or it has not been checked by qualified experts, never use it for charging. Even very low charging currents can cause serious damage and in particular fires if the socket or electrical installation is in bad condi-tion. If necessary, get expert assistance from a qualified electrical installation specialist.
WARNING
If a 110 Volt outlet is being used for charging, never charge 2 or more vehicles on outlets of the same fuse at the same time. Use a different fuse circuit for charging another vehicle. Al-ways comply with the maximum load for the fuse circuit used. If necessary, get expert assis-tance.
