Servicing double-insulated products
(230V-240V)
In a double-insulated product, two systems of insulation are provided instead of
grounding. No grounding means are provided on a double-insulated product nor should
a means for grounding be added to the product. Servicing a double-insulated product
requires extreme care and should only be done by qualified service personnel with
knowledge of the system under his or her responsibility. Replacement parts for a double-
insulated product must be identical to those parts in the product. The symbol is marked
on the double-insulated product.
