a) Choose the correct charging current via selector switch
b) Plug in the charger into the power socket.
The charging process starts automatically and runs through the following three charging phases:
1. Charging step: constant current (CC)
This charging step is indicated by the
red charge-control LED
(5).
During the constant current phase, the battery is being charged to 80% of its capacity.
2. Charging step: constant voltage (CV)
This charging step is indicated by the
yellow charge-control LED
(4).
During the constant voltage phase the battery is being charged to its maximum capacity.
3. Charging step: float charge (battery is fully charged)
This charging step is indicated by the
green charge control LED
(3).
As soon as the battery has reached its full capacity, the charger switches into float-charge mode. The charger can
now be disconnected from the battery (see pt. III ) or remain at the battery in float- charge mode. This guarantees
a full battery at any time and therefore an instant operational readiness.
III. Disconnect the charger from the battery:
a) Disconnect the charger from the mains supply;
b) Disconnect the charger from the battery;
Charging advice:
If the charger will be disconnected from the battery during the charging process, please disconnect the
charger from the mains supply immediately. For starting a new charging process please comply with the rele-
vant points (see point I)
For increasing the lifetime of a battery please do not stop a charging process before the automatic switching
to float charge mode (3
rd
charging step).
