Power sources that can be used

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.

Power sources

● 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.

mended.

● Rain-tight socket

When charging outdoors, connect the plug to a rain-tight socket, and ensure

that the plug remains waterproof while the plug is connected.

● Dedicated circuit

• To reduce the risk of fire, connect only to an at least 13A branch circuit

with an over-current protection.

• To reduce the risk of electric shock when working with the plug, connect

2

to a socket that has a Residual Current Circuit-Breaker (RCCB) installed.

● Remote switch
