Warnings And Safety Notes, Please Read And Observe - GRAUPNER ULTRA TRIO PLUS 16 Operating Manual

 This product isn't designed for use by children under the age of 14, it isn't 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 or 100~240V AC main
socket only. It is not permissible to modify the charger in any way. Never use both inputs AC and DC at the
same time!
 The charger and the battery to be charged should be set up on a heat-resistant, non-infl ammable and
non-conductive surface before use. Never place the charger directly on a car seat, carpet or similar. Keep
all infl ammable and volatile materials well away from the charging area. Provide good ventilation. Defective
batteries can explode or burn!
 Connect the charger 12DC input directly to the car battery using the original cables and connectors sup-
plied. The car's engine must be stopped all the time the charger is connected to the car's battery. Do not
recharge the car battery at any time when the charger is connected to it.
 The charge output sockets and connecting leads must not be modifi ed, 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 14 cells, Lithium-Ion / Li-Mn / Lithium-Polymer / LiFePO
(LiFe) batteries of more than 6 cells, or lead-acid batteries with a nominal voltage of more than 12V.
- 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 fi tted 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 fi tted to the charge leads, please always connect the
charge leads to the charger fi rst, 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 has a poorly defi ned voltage peak, the charger may fail to detect the fully
charged state.
 Before charging please check: 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 connections fi rm, 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.
