lithium battery (LiFePO
4
) with BMS.
Rechargeable batteries with other voltages
cannot be charged!
Disconnect all consumers from the rechargeable battery.
If the rechargeable battery is built into a vehicle, switch off the ignition and all
consumers.
First, connect the charger to the power supply (220 – 240 V AC, 50/60 Hz).
Then, you may select from various functions by pressing the MODE button (8).
Please strictly observe the information of the manufacturer of the rechargeable
battery concerning permissible final charging voltage and maximum charging
current when selecting the correct operating mode.
