Warnings And Safety Notes - GRAUPNER SWITCHING POWER SUPPLY 5-15V 0-40A Manual

WARNINGS AND SAFETY NOTES

• This product isn't designed for use by children under the age of 14, it isn't a toy! This
appliance is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instruction concerning use of the appliance by a person responsible for
their safety. Children should be supervised to ensure that they do not play with the
appliance.
• 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 220~240V AC main socket only. 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!
• 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 at each output at any one time.
• The following types of battery must not be connected to the charger:
• Ni-Cd / Ni-MH batteries, lead-acid batteries with a nominal voltage of more than 12V
or less than 6V, Lithium-Ion / Li-Mn / Lithium-Polymer / LiFePO 4 (LiFe) batteries
with less than 2 cells and more than 3 cells (4 cells for LiFePO 4) .
• Batteries which require a different charge method from CC/CV 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 always
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.
