34 | Battery and charger
6.3 Intended use
This charger charges the 28V Li-ion battery of the M 28/V28 system delivered with the battery-
powered devices. This device must be used only as specified and intended.
6.4 Power line connection
Only connect to single-phase AC current and only to the line voltage specified on the type
plate. Connection to power sockets without an earthing contact is possible, because this is a
protection class II design.
6.5 Li-Ion battery
For safety reasons (air transport regulations), the batteries are delivered uncharged. Before first
use, the battery must be completely charged.
LED charge status display Figure 1
If the battery is not used for a prolonged period of time, the battery switches to standby mode.
To use again, the battery must be reactivated (recharged).
The charge status can be called up by pressing the button on the battery
(see Fig 1). To do this, the battery can remain in the battery-powered device, but it must
be switched off at least 1 minute beforehand (otherwise the display will not be accurate). The
number of glowing LEDs indicates the charge status.
The basic principle is: If the battery-powered device does not function after the battery is
inserted, put the battery onto the charger for testing. The displays on the battery and charger
give information about the battery charge status.
At low temperatures, the work can be still be carried out with lower performance.
For best operational readiness, the batteries must be fully charged after use.
