If the charger is operated via the DC input (11 - 18 V/DC), disconnect the charger from the voltage/
power supply.
Then disconnect the connected rechargeable battery from the charger. Do not use the charger again -
bring it to a specialist workshop.
d) Operation
•
The charger may be operated either via the mains voltage (switchable 115 V/AC or 230 V/AC, 50/60 Hz)
or via a stabilised direct voltage of 11 - 18 V/DC (e.g. via an external vehicle lead battery or a suitable
mains adapter).
Use only one of the two connection types, but never both at once. This may damage the charger.
•
Do not wear any metal or conductive materials, such as jewellery (necklaces, bracelets, rings, etc.) while
you are working with the charger or batteries. A short-circuit at the rechargeable battery or charging
cable poses a danger of burns and explosion.
•
Do not operate the product unattended. Despite a considerable number of protective circuits, it is impos-
sible to exclude the possibility of malfunctions or problems during the charging process.
• Ensure that there is sufficient ventilation during operation. Never cover up the charger. Leave enough
of a distance (at least 20 cm) between charger and other objects. Overheating causes a danger of fire!
•
The charger must only be used to charge (or discharge) rechargeable batteries of types NiMH, NiCd,
LiIon/LiPo/LiFe and lead batteries. Never charge any other rechargeable battery types or non-recharge-
able batteries. There is great danger of fire or explosion!
• Always connect the charging cable to the charger first. Only then must the rechargeable battery be con
-
nected to the charging cable.
When disconnecting, proceed in reverse order - first disconnect the rechargeable battery from the charg
-
ing cable, then the charging cable from the charger.
If the order is chosen incorrectly, there may be a short-circuit of the charger plugs; there is a danger of
fire and explosion!
•
Never connect several charges to each other.
•
The charger has two charging channels that are independent of each other, so that up to two recharge-
able batteries/rechargeable battery packs can be charged (or discharged) at once. However, only con-
nect a single rechargeable battery/rechargeable battery pack to each of the two charging channels.
Never connect the charging channels to each other!
•
Only operate the product in moderate climate, never in tropical climate. For more information on accept-
able environmental conditions, see the chapter "Technical Data".
•
Never operate the device immediately after it was taken from a cold room to a warm room. The resulting
condensation may lead to malfunctions or damage!
Let the product reach room temperature before taking it into operation again. This may take several
hours!
• Avoid operation in direct proximity of strong magnetic or electromagnetic fields, transmitter aerials or HF
generators. This can affect the control electronics.
