THIS NOTE MUST BE READ IN CON-
JUNCTION WITH THE PRODUCT DATA
SHEET/CATALOG. FAILURE TO
OBSERVE THE ADVICE IN THIS INFOR-
MATION SHEET AND THE OPERATING
CONDITIONS SPECIFIED IN THE PROD-
UCT DATA SHEET/ CATALOG COULD
RESULT IN HAZARDOUS SITUATIONS.
1. MATERIAL CONTENT AND PHYSICAL
FORM
Electrical connectors do not usually con-
tain hazardous materials. They contain
conducting and non-conducting materi-
als 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 Reliabil-
ity 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 manu-
factured from either: Copper, copper
alloys, nickel, alumel, chromel or steel. In
special applications, other alloys may be
specified.
2. FIRE CHARACTERISTICS AND ELEC-
TRIC SHOCK HAZARD
There is no fire hazard when the connec-
tor 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 compo-
nent parts may cause electric shock or
burns. Live circuits must not be broken
by separating mated connectors as this
may cause arcing, ionization and burn-
ing. Heat dissipation is greater at maxi-
mum resistance in a circuit. Hot spots
may occur when resistance is raised
locally by damage, e.g. cracked or
deformed contacts, broken strands 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/Catalog are exceeded and can
cause breakdown of insulation and
hence electric shock. If heating is
allowed to continue it intensifies by fur-
ther increasing the local resistance
through loss of temper of spring con-
tacts, formation of oxide film on contacts
and wires and leakage currents through
carbonization of insulation and tracking
paths. Fire can then result in the pres-
ence of combustible materials and this
may release noxious fumes. Overheating
may not be visually apparent. Burns may
result from touching overheated compo-
nents.
3. HANDLING
Care must be taken to avoid damage
to any component parts of electrical con-
nectors during installation and use.
Although there are normally no sharp
edges, care must be taken when handling
certain components to avoid injury to fin-
gers. Electrical connectors may be dam-
aged in transit to the customers, and
damage may result in creation of haz-
ards. Products should therefore be exam-
ined prior to installation/use and rejected
if found to be damaged.
4. DISPOSAL
Incineration of certain materials may
release noxious or even toxic fumes.
5. APPLICATION
Connectors with exposed contacts
should not be selected for use on the
current supply side of an electrical cir-
cuit, 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 poten-
tially 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 or insulators, no solder
blobs, loose strands, conducting lubri-
cants, swarf, or any other undesired con-
ducting particles. Circuit resistance and
continuity check should be made to
make certain that there are no high resis-
tance joints or spurious conducting
paths. Always use the correct application
tools as specified in the Data Sheet/Cata-
log. Do not permit untrained personnel to
wire, assemble or tamper with connec-
tors. For operation voltage please see
appropriate national regulations.
IMPORTANT GENERAL INFORMATION
(i) Air and creepage paths/Operating volt-
age. The admissible operating voltages
depend on the individual applications
and the valid national and other applica-
ble safety regulations.
For this reason the air and creepage path
data are only reference values. Observe
reduction of air and creepage paths due
to PC board and/or harnessing.
(ii) Temperature
All information given are temperature
limits. The operation temperature
depends on the individual application.
(iii) Other important information
Cannon continuously endeavors to
improve their products. Therefore, Can-
non products may deviate from the
description, technical data and shape as
shown in this catalog and data sheets.
