Operating & Safety Instructions
Attention should also be given to the use of extension cables as power leads. Excessive cable
lengths from the supply point to the battery charger will result in significant voltage drop, leading to
a reduction in the chargers efficiency. In addition, inadequate sized cable cores will have a limiting
effect on its current carrying capacity, which will again lead to a reduction in the chargers efficiency.
Both of these can result in over-heating of the cable with an increased risk of fire, short circuits, or
damage to the components themselves.
The charger requires a minimum battery voltage of 1.5 volts per battery (overall for two batteries 3
volts, for 4 batteries 6 volts for 8 batteries 12 volts and 18V for 72V). If the voltage is below these
values then the charger will not function (Charger will not detect batteries to begin charge.) If the
batteries have fallen to such a poor state they will have to be removed from the machine and charged
individually with an independent charger until the optimum voltage has been reached. This is best
performed at very low currents to 'recover' the batteries if sulphation has already started i.e. a 'trickle'
charger. This can take several hours, possibly days. Careful monitoring of the rise of battery voltage
will indicate when recovery has been achieved.
TOPPING UP
The batteries installed on this machine are Maintenance Free, therefore DO NOT REFILL with
de-ionised water. Irreparable damage will occur.
