Operation

Prior to start-up

3 Read the battery operating instructions before
connecting up the charger.
3 Observe the vehicle manufacturer's
recommendation if the battery is still
connected to the vehicle.
3 Clean the battery terminals. When doing so,
do not allow the dirt to come into contact
with your eyes or mouth.
3 Ensure adequate ventilation. Hydrogen gas
(electrolytic gas) may escape from the battery
during charging and trickle charging.

Connection

3 Connect the (+) terminal (red) (5) of the
charger to the (+) terminal of the battery.
3 Connect the (–) terminal (black) (6) of the
charger to the (–) terminal of the battery.
3 The (–) terminal (black) (6) can also be
connected to the car body, however well
away from fuel pipes.
Note: Make sure the (+) and (–) terminals are firm.
3 Only then is the power cord to be connected
to the mains current.

As soon as the charger has been connected to the
mains current, it switches automatically to standby
mode. The "Power" indicator will light up.
Note: The charger is provided with reverse
polarity protection. The LED (–)(+) (9) will light up
if the (+) and (–) terminals (5) (6) are interchanged
on connection.

Disconnection

3 Switch the charger to standby by pressing
the Mode selection button.
3 Always start by disconnecting the power cord
from the mains current.
3 Disconnect the (–) terminal (black) (6)
of the charger from the (–) terminal of the
battery.
3 Disconnect the (+) terminal (red) (5)
of the charger from the (+) terminal of the
battery.

Memory function

If the C7 charger is disconnected from the mains
during charging, the unit stores the mode imple-
mented. On re-connection to the mains and if the
battery is of the same type (12 V or 24 V), the unit
starts up automatically in the last mode. In the
case of a different type of battery (12 V and 24 V),
it switches to standby.
Caution: If mode 2 or 6 was last implemented
(cold battery or AGM battery) and a WET or GEL
battery is then connected, this may result in over-
charging and damage to the battery. In such cases
the mode is always to be set appropriately for
the battery to be charged. There is no memory
function with modes 3 and 4.
