2 Preparing the battery charger for use
The charger is designed for maintenance-free lead-cell drive batteries with a nominal
voltage of either 24 V or 36 V (see rating plate) and a rating of 160 ... 180 Ah. The battery
is optimally charged according to a IUIa curve with equalising charge corresponding to
the specifications of the battery manufacturer. The battery charger is already correctly
installed in the cleaning unit.
First connect the charger to the batteries to be charged. The coded charging plug
prevents wrong polarity. Then connect the charger to an earthed socket in the 230 V
mains network. For this the following mains-side fusing is to be provided: blow-out fuse
minimum 10 A gL or safety cut-out with minimum 10 A (B or C characteristic). The
charging process begins automatically.
The battery charger is equipped with 4 LED displays.
