pack power corresponds to the voltage on the rating
plate. Also make sure that the voltage of your charger
corresponds to that of your mains.
Your DEWALT charger is double
insulated in accordance with AS/NZS 60335.
Using an extension cable
An extension cord should not be used unless absolutely
necessary. Use an approved extension cable suitable for
the power input of your charger (see technical data). The
minimum conductor size is 1 mm2; the maximum length
is 30 m.
