Servicing Of Double-Insulated Products - Knoll Stroke 665/420 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.
