Product Safety Information
THIS NOTE SHOULD BE READ IN CON-JUNCTION
WITH THE PRODUCT DATA SHEET/CATALOGUE.
FAILURE TO OB-SERVE THE ADVICE IN THIS INFOR-
MATION SHEET AND THE OPERATING CONDITIONS
SPECIFIED IN THE PRODUCT DATA SHEET/
CATALOGUE COULD RESULT IN HAZAR-DUOUS
SITUATIONS.
1. MATERIAL CONTENT AND PHYSICAL
2. FIRE CHARACTERISTICS AND ELECTRIC
3. HANDLING
FORM
Electrical connectors do not usually contain
hazardous materials. They contain conducting and
non-conducting materials and can be divided into
two groups.
a) Printed circuit types and low cost audio types
which employ all plastic insulators and casings.
b) Rugged, Fire Barrier and High Reliability types
with metal casings and either natural rubber,
synthetic rubber, plastic or glass insulating
materials.
Contact materials vary with type of connector and
also application and are usually manufactured from
either copper, alloys, nickel, alumel, chromel or
steel. In special applications, other alloys may be
specified.
SHOCK HAZARD
There is no fire hazard when the connector is
correctly wired and used within the specified
parameters.
Incorrect wiring or assembly of the connector or
careless use of metal tools or conductive fluids,
or transit damage to any of the component parts
may cause electric shock or burns. Live circuits
must be broken by separating mated connectors
as this may cause arcing, ionisation and burning.
Heat dissipation is greater at maximum resistance
in a circuit. Hot spots may occur when resistance
is raised locally by damage, e.g. cracked or
deformed contacts, broken strangs of wire. Local
overheating may also result from the use of the
incorrect application tools or from poor quality
soldering or slack screw terminals. Overheating may
occur if the ratings in the Product Data Sheet/
Catalogue are exceeded and can cause breakdown
of insulation and hence electric shock.
If heating is allowed to continue it intensifies by
further increasing the local resistance through loss
of temper of spring contacts, formation of oxide
film on contacts and wires, and leakage currents
through carbonisation of insulation and tracking
paths. Fire can then result in the presence of
combustible materials and this may release noxious
fumes. Overheating may not be visually apparent.
Burns may result from touching overheated
components.
Care must be taken to avoid damage to any
component parts of electrical connectors during
installation and use. Although there are normally
no sharp edges, care must be taken when handling
certain components to avoid injury to fingers.
4. DISPOSAL
5. APPLICATION
Electrical connectors may be damaged in transit to
the customers, and damage may result in creation
of hazards. Products should therefore be examined
prior to installation/use and rejected if found to be
damaged.
Incineration of certain materials may release
noxious or even oxid fumes.
Connectors with exposed contacts should not be
selected for use on the current supply side of an
electrical circuit, because an electric shock could
result from touching exposed contacts on an
unmated connector. Voltages in excess of 30 V ac
or 42.5 V dc are potentially hazardous and care
should be taken to ensure that such voltages can
not be transmitted in any way to exposed metal parts
of the connector body. The connector and wiring
should be checked, before making live, to have no
damage to metal parts of insulators, no solder blobs,
loose strands, conducting lubricants, swarf, or any
other undersired conducting particles. Insulation
resistance should be checked to make certain that
no low resistance joints or spurious conducting path
are existing between contacts and exposed metal
parts of the connector body. Further the contact
resistance of the connectors should be measured
within the electrical circuit in order to identify high
resistances which result in excessive connector
heating.

IMPORTANT GENERAL INFORMATION.
1. Air and creepage paths/Operating voltage
2. Temperature
3. Other important information
4. Harnessing and Assembly Instructions
The admissible operating voltages depend on the
individual applications and the valid national and
other applicable safety regulations.
For this reason the air and creepage path date
are only reference values. Observe reduction of air
and creepage paths due to PC board and/or harnes-
sing.
All information given are temperature limits. The
operation temperature depends on the individual
application.
Cannon continuously endeavours to improve their
products. Therefore, Cannon products may deviate
from the description, technical data and shape as
shown in this catalogue and data sheets.
If applicable, our special harnessing and/or assem-
bly instruction has to be adhered to. This is provid-
ed at request.
