Residual current device
The standard version of your vehicle is equipped with a residual cur-
rent device that will interrupt the electric circuit in case of a possible
residual current. Should there be a power failure, the fault current
circuitbreaker('fastinterrupt' =FIswitch) willinterrupt theentire
230Velectriccircuit.
After putting the electric system into operation, the function of the re-
sidual current device must be checked. After voltage has been applied
to the switch

. The rocker switch

(p. 70)jumpsdown;
after it has successfully been checked it must be switched back up
to the "On" setting.
This check should be carried out at least once a month to ensure that
the residual current device functions perfectly in case there should be
a fault in the current.
Repairs must not be carried out on the residual
current device.
A residual current device does not guarantee any
protection against the danger from an electric
shock. It does not protect against possible electrical
accidents.
