01 C30 ELECTRIC

Control unit
The charging cable's control unit
has an integrated ground fault
breaker. Adjacent to the unit's ON
button (1) is an indicator lamp - it
can have the following meanings:
Lamp Information
On The charging cable is routing
electricity and the car's batter-
ies are being recharged.
Off The ground fault breaker has
triggered - there may be a fault
in the charging cable or in the
car's electrical system.
Off The 230 V AC mains circuit's
fuse may have been tripped -
check the mains fuse.
Lamp Information
Off The 230 V AC mains circuit's
fuse may have been tripped -
check that the mains fuse value
is programmed into the car's
electrical system (see next sec-
tion "Charging current").
Off The electric socket has no
ground connection - connect
the charging cable into a
grounded electrical socket.
WARNING
In the event of malfunctioning or the slight-
est doubt about a function - contact the
Volvo workshop that was specified when
the car was delivered (see page 4).
•
Never carry out fault diagnosis or
repairs yourself.
Charging current
Before the car's electrical system is connected
to a grounded 230 V AC mains circuit it is
important that the car receives correct infor-
mation about the current intensity that the
230 V system has. The setting is made with the
left-hand stalk switch thumbwheel:
•
Select 6, 8, 10 or 16 A from the menu. (For
more information, see page 30.)
IMPORTANT
Ensure that the correct fuse value
(6/8/10/16 A) is specified for the car's bat-
tery charging.
Tip
Not all 230 V sockets state their level of fuse
protection. If the socket's capacity is unknown,
choose one of the lower alternatives - 6 A or
8 A - to avoid the risk that the mains fuse is
tripped after a short time. It is better that the
batteries receive low and slow charging than
no charging at all.
The following example explains the logic:
Example 1
If the car is connected to 230 V/10 A and the
control program is set at 16 A, the car will
attempt to draw 16 A from the 230 V mains cir-
cuit - after a while the overloaded 10 A fuse will
be tripped and battery charging stopped.
Example 2
If the car is connected to 230 V/10 A but the
control program is set at 10 A, the car will draw
10 A from the mains circuit - if further consum-
ers are connected to the same socket then
there is a risk that the fuse will be overloaded
