Servicing Of Double-Insulated Products - Knoll 400 User Manual

4.4 Servicing of double-insulated
products
In a double-insulated product, two systems of insulation
are provided instead of grounding. No grounding means
is provided on a double-insulated product, nor is a
means for grounding to be added to the product.
Servicing a double-insulated product requires extreme
care and knowledge of the system, and is to be done
only by qualified service personnel.
Replacement parts for a double-insulated product
must be identical to the parts they replace. A double
insulated product is marked with the words "DOUBLE
INSULATION" or "DOUBLE INSULATED". The symbol
(square within a square) is also able to be marked on the
product.
