Power sources that can be used
●Connect to an AC 220 V - 240 V socket with a Residual Current Cir-
cuit-Breaker (RCCB) and a circuit breaker. Use of a 13A individual
circuit is strongly recommended to ensure charging cable will oper-
ate properly.
● We strongly recommend that you use an exclusive connection from
the junction box for charging.
If you connect on a socket that is on a shared circuit, and other
electrical appliances are used on other sockets on the same circuit,
then the circuit breaker might trip.*
● Ensure that the junction box is equipped with a Residual Current
Circuit-Breaker (RCCB). If it is not, have one installed by a duly
qualified professional.
● When charging outdoors, make sure to connect to a rain-tight
socket that is certified for outdoor use.
Checking Residual Current Circuit-Breaker (RCCB) operation
before its use is recommended.
● Check whether there are any local EV-charging regulations in
place, and adhere to them.
*: For detailed information, consult an electrician.
An external power source that fulfills the following criteria is
necessary for charging this vehicle. Confirm this before
charging.
WARNING
■ Warnings for electrical faults
Make sure to observe the precautions in this Owner’s Manual when
charging the vehicle.
Failure to use a power source that fulfills the requirements, or failure to
observe regulations while charging could lead to an accident, possibly
resulting in death or serious injury.
