The mains supply unit is a special switching power supply unit that can replace the rechargeable battery
on an electric tool where a mains supply is available. This is a low voltage source and together with its
parameters corresponds to the 18V rechargeable battery. The mains supply unit was designed for
powering an electric tool employed in intermittent operation and a capacity of up to 400W and displays
its current status by means of an LED indicator.

Short-circuit protection

The protection system is triggered in the event that
the device is exposed to a load of more than 45A
(short circuit). The electric circuit is interrupted and
completed again after approx. 1 seconds. In case
of a sustained short circuit the cycle (test) in a
period of 1 s repeated appeals to the thermal
protection.

Temperature protection

NTC thermistors serve as temperature probes. They
protect the transistors and rectifier diodes against
any excessive temperature. The device is shut
down if the temperature of these components
reaches critical values (diode 95°C, transistor
60°C). The device is ready for service again after 1
– 4 minutes.
LED explanation
1. The device is ready for operation if the red LED
is continuously illuminated.
2. A flashing LED indicates that the device has
been switched off. There can be 3 reasons for
this:
There has been an excessive rise in
temperature (temperature protection)
There has been a short circuit (short-circuit
protection).
transistor:................... 60°C +/-10% max.
rectifier diode............. 95°C +/-10% max.
ENGLISH
The device is faulty.
Disposal
Components of the unit are recyclable material
and should be put to recycling.
For this purpose registered and certified recycling
companies are available. For an environmental-
friendly disposal of the non-recyclable parts (e.g.
electronic waste) please contact your local waste
disposal authority.
For EU countries only:
Do not dispose of electric tools with
domestic waste. In accordance with
European Directive 2002/96/EC on
waste electrical and electronic
equipment and its implementation as national law,
electric tools that are no longer serviceable must be
collected separately and utilised for
environmentally compatible recycling.
Used removable batteries must not be thrown in
fire or in the household rubbish.
