Instruction Manual PERCEDOS

Function description:
PERCEDOS
®
is a portable protective system (IC-RCD*) including communication
interface to the electrical vehicle and intended for use on the charging cable in
mode 2. The device checks the power supply for proper function and only allows
current to be drawn from a safe power source.
The charger of the electrical vehicle controls the charging procedure of the bat-
teries and prompts the PERCEDOS
®
to switch the charging procedure on or off
by means of the communication connection. In order to activate the charging
procedure, the PERCEDOS
®
must be activated. An inactive PERCEDOS
®
status
is the equivalent of a standby function. Without PERCEDOS
®
, it is impossible to
charge the vehicle in mode 2.
When connected to an outlet, the device automatically recognizes whether
mains voltage is present at the feed point. It is not necessary to manually switch
on the PERCEDOS
®
If mains voltage is recognized, the device automatically starts the protective
ground monitoring. This monitoring function is constantly active as long as the
device is operated with mains voltage and monitors the protective ground con-
nection between PERCEDOS
®
and the outlet for the presence of the protective
ground wire and its freedom from faults.
So that the PERCEDOS
®
can detect external voltage on the protective ground,
the device must be connected to the electrical vehicle. The function external
voltage detection is also automatically activated as soon as the plug connection
to the vehicle has been created and detected.
As soon as the PERCEDOS
®
finds one of these faults, the charging procedure is
immediately interrupted or a beginning of the charging procedure is prevented
The fault current circuit breaker integrated into the device additionally protects
the user against an electrical accident in case of a system defect.
Sequence of the charging procedure:
1. Check the maximum possible charging current of the outlet and reparame-
terize the charging current of the PERCEDOS
®
after connection to the mains
voltage, if necessary.
2. Connect PERCEDOS
®
to outlet (mains voltage) and to vehicle.
3. PERCEDOS
®
automatically starts its test sequence; (outlet and connection
cables) are checked for proper function.
4. After the test sequence and if no malfunctions have been determined, the
PERCEDOS
®
is ready to activate the charging procedure.
5. For this, the PERCEDOS
®
must be activated in operating status.
6. Check operating status and switch to active if necessary
7. The charging current of the PERCEDOS
®
may need to be reparameterized.
8. The vehicle electronics switch the PERCEDOS
®
on and off for the charging
procedure.
