2-2. Charging
Connect to an AC 220 V - 240 V
socket with a Residual Current
Circuit-Breaker (RCCB) and a
circuit breaker. Use of a 13A indi-
vidual circuit is strongly recom-
mended to ensure AC charging
cable will operate 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 Cur-
rent 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) opera-
tion before its use is recom-
mended.
• Check whether there are any local
BEV-charging regulations in place,
and adhere to them.
*: For detailed information, consult an
electrician.
■The charging environment
For safe charging, the following charging equipment and settings are recommended.
●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
to a socket that has a Residual Cur- rent Circuit-Breaker (RCCB) installed.
●Remote switch
Allows the electricity from the socket to
be interrupted by operating a switch,
thus allowing safe removal and insertion
of the plug on rainy days.
