II. Start charging:
a) Plug in the power cable into the power socket.
b) Switch on the charger with the On/Off Switch (2)
The charging process starts automatically and runs through the following three charging phases:
1. charging phase: constant current (CC)
This charging step is indicated by the
red charge-control LED
(8).
During the constant current phase, the battery is being charged to 80% of its capacity.
2. charging phase: constant voltage (CV)
This charging step is indicated by the
yellow charge-control LED
(7).
During the constant voltage phase the battery is being charged to its maximum capacity.
3. charging phase: float charge / battery is fully charged
This charging step is indicated by the
green charge control LED
(6).
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 disconnection the charger) 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) Switch off the charger or 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, the charge current will be in-
terrupted immediately. In that case please disconnect the charger from the mains supply. For starting a new
charging process please comply with the relevant points (see pt.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).
