CHARGING THE BATTERIES
As the IMPULSE S (8 A) charger aligns the charge curve with the AGM batteries' charge level, you
can recharge your wheelchair after each use. This avoids any aggressive battery charging and the
"memory effect".
Recharge the wheelchair, at the latest, when the charge indicator on the steering unit goes into the red
zone. If, despite this, you continue driving, eventually only the last red diode lights up and flashes
continually, indicating that the batteries are nearly flat. If you disregard this warning signal, too, an
error message will shortly appear indicating that the batteries can no longer provide power for driving.
The batteries should therefore be charged before these error messages appear, using the supplied
battery charger IMPULSE S (8 A). Avoid the batteries becoming drained, in any case.

SETTING UP THE CHARGER
When setting up the charger, ensure that it is well-ventilated on all sides. A minimum of 10 cm space
should be left free around the unit for this purpose. If the charger is insufficiently ventilated so that the
unit heats up, the charging rate will fall which will extend the charging time. If the charger overheats (>
+50° C), it will stop charging.
The charger should only be used from a wall socket with a voltage of 230V – 50/60Hz and in well-
ventilated, dry areas.

FIRST USE
First put the plug into the wall socket. After an LED combination has lit up, the charger switches to
STANDBY. Both LEDs (green and yellow) are active.
Next, connect the charger cable with the three-pin plug to the loader socket on the electric
wheelchair's steering unit. Once connected to the batteries, the charger automatically begins charging.
Now only the yellow LED is active.
When charging is complete, the yellow LED goes out and the green LED comes on. Now remove the
charger cable from the steering unit. The charger switches back to STAND-BY mode (yellow and
green LEDs active).
