Warning - risk due to the electrical current!
The engine voltage system should only be charged with a 24-volt charging device!
: 24-volt charging device
1 Four 12-volt batteries ➔ Engine voltage 48 volts
2 One 12-volt battery ➔ Control voltage 12 volts
3 One 24-volt charging device
4 Two charging devices, each with 24 volts
Two 24-volt (4) charging devices must be connected to the battery terminals of the
48-volt engine voltage (1) as in the figure above.
Alternatively, the network with 48-volt engine voltage (1) can be charged in two
steps with a 24-volt charging device (3).
The 24-volt charging device (3) should NOT be used to charge the control voltage!
