WARNINGS AND SAFETY NOTES

• Please open the instruction file on the CD and read the complete instruction!

• This product is not designed for use by children under the age of 14; it is not a toy!

• Protect the charger from dust, damp, rain, heat (e.g. direct sunshine) and vibration. It should only be operated in dry

indoor conditions.

• The case slots serve to cool the charger, and must not be covered or enclosed; set up the charger with space round it,
so that cooling air can circulate unhindered.

•

The charger is designed to be powered by a 12 V DC car battery or power supply Order-No. 6460 or 6461. It is not

permissible to modify the charger in any way. You must not connect AC power to the DC input.

• The charger and the battery to be charged should be set up on a heat-resistant, non-inflammable and non-conductive
surface before use. Never place the charger directly on a car seat, carpet or similar. Keep all inflammable and volatile
materials well away from the charging area. Provide good ventilation. Defective batteries can explode or burn!

• Connect the charger ’s 12 V DC input directly to the car battery using the original cables and connectors supplied. The
car’s engine must be stopped all the time the ULTRA DUO PLUS 45 is connected to the car’s battery. Do not recharge

the car battery at any time when the ULTRA DUO PLUS 45 is connected to it.

• The charge output sockets and connecting leads must not be modified, and must not be inter-connected in any way.
There is a danger of short-circuit between the charge outputs and the vehicle’s bodywork when the charger is
connected to the car battery. The charge leads and connecting leads must not be coiled up when the charger is in use.
Avoid short-circuiting the charge output or the model battery with the car bodywork. For this reason the charger must
never be placed directly on the vehicle’s bodywork.

• Never leave the charger running or connected to the car battery unsupervised.

• Only one battery may be connected to the unit for charging at any one time.

• The following types of battery must not

be connected to the charger:

- Ni-Cd / Ni-MH batteries consisting of more than 18 cells, Lithium-Ion / Lithium-Manganese / Lithium-Polymer / LiFePO

4

(LiFe) batteries of more than 7 cells, or lead-acid batteries with a nominal voltage of more than 12V or 24V.

- Batteries which require a different charge method from Ni-Cd, Ni-MH, Lithium or lead-acid types.

- Faulty or damaged cells or batteries.

- Batteries consisting of parallel-wired cells, or cells of different types.

- Batteries consisting of old and new cells, or cells of different makes.

- Non-rechargeable batteries (dry cells). Caution: explosion hazard!

- Batteries which are not expressly stated by the manufacturer to be suitable for the currents which this unit delivers

during the charge process.

- Packs which are already fully charged or hot, or only partially discharged.

- Batteries or cells fitted with an integral charge circuit or charge termination circuit.

- Batteries installed in a device, or which are electrically connected to other components.

• To avoid short-circuits between the banana plugs fitted to the charge leads, please remember always to connect the
charge leads to the charger first, and only then to the battery to be charged. Reverse the sequence when disconnecting.

• As a basic rule always check that the charge quantity is approximately the same as you expected after

the charger has
indicated that the pack is fully charged. This is a simple method of detecting a problem reliably and in good time, should
the charge process be terminated prematurely for any reason. The likelihood of premature termination varies according
to many factors, but is at its highest with deep-discharged packs, low cell counts and particular cell types which are

known to cause problems.

• We recommend that you carry out a series of test charges to satisfy yourself that the automatic termination circuit is
working perfectly. This applies in particular when you are charging packs consisting of a small number of cells. If the
cells feature a poorly defined voltage peak, the charger may fail to detect the fully charged state.

• Before charging please check the following: have you selected the appropriate charge program for the battery?
Have you set the correct charge or discharge current? Have you set the important cut-off voltage when charging Ni-Cd
and Ni-MH packs? Are all connectors firmly inserted, or is there an intermittent contact at any point in the circuit? Please
bear in mind that it can be dangerous to fast-charge batteries. For example, if there is a brief interruption due to an
intermittent contact, the result is inevitably a malfunction such as a restart of the charge process, which would result in
the pack being massively overcharged.

• Be careful! Batteries may explode or burn if the charger develops a fault or if the user chooses the wrong
charging program and / or parameters.
