Product overview
Specifications
With the advancement of technology within Dyson products, more sensitive electronic components
are being used. Certain variants of Dyson products (
iinncclluuddiinngg DDCC1155
) contain Printed Circuit
Boards (PCBs) which are made from electronic components that are susceptible to damage by
electrostatic discharge.
Electrostatic Discharge or ESD is described as the rapid transfer of electricity from one object to
another. Static electrical charge is created by the contact and separation of different materials e.g.
the motion of walking can create static electricity, as shoes contact and then separate from the floor.
Static electricity is released when two charged objects make contact and this is when sensitive
electrical components can be irreversibly harmed.
The damage caused by ESD varies from a product not functioning to a depreciation of the life of a
product; therefore it isn’t always possible to detect ESD damage.
In order to protect relevant Dyson product and components/assemblies from ESD damage, the
following precautions must be taken when repairing or examining product:
Using a socket polarity tester, verify that there is an adequate earth. If there is not an adequate
earth, use an alternative adequately earthed socket.
All repair/investigation work must be carried out on an anti-static mat that is earthed via an earthing
plug.
All personnel repairing/investigating Dyson product must wear an anti-static wrist strap that is
connected to an earthed anti-static mat (see Fig.1, page 3).
