The battery pack is not charged in the factory. The battery pack must be charged
before it is used the first time. A new battery pack or a battery pack which has not
been used for a longer time attains full capacity after several charge/ discharge
cycles.
1. Connect the AC adapter (24 V, 3 A) to the AC power, using the power cable
supplied with the option.
2. Connect the output of the AC adapter to the POWER SUPPLY 24 V connector.
The output of the battery pack is automatically switched off if the AC adapter is
connected.
The charging state is indicated by the LED named "CHARGE":
Charging
The LED is on. Charging is in progress.
The LED is off. Charging is completed.
Fault
The LED flashes. The battery temperature is outside the permissible range or the
battery voltage is too low (battery deeply discharged or defective).
Note:
After charging has been completed (LED is off), trickle charging is performed at a
reduced current.
Charging is terminated by an evaluation of the battery voltage (-
V procedure) and
the battery temperature (dT/dt procedure). It is limited in addition to approx. 6 h by
a timer.
3. Disconnect the AC adapter. The battery pack is ready for operation.
Charging should be performed at a constant ambient temperature as temperature
variations may cause the charger to be switched off too early.
