FAILURE

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 contain

hazardous materials. They contain conduct-

ing 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,

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 component

parts may cause electric shock or burns.

Live circuits must not be broken by sepa-

rating mated connectors as this may

cause arcing, ionization 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

strands of wire. Local overheating may also

result from the use of the incorrect applica-

tion 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 further increasing the local

resistance through loss of temper of spring

contacts, formation of oxide film on contacts

and wires and leakage currents through car-

bonization of insulation and tracking paths.

Fire can then result in the presence of com-

bustible materials and this may release nox-

ious fumes. Overheating may not be visually

apparent. Burns may result from touching

overheated components.

3. HANDLING

Care must be taken to avoid damage

to any component parts of electrical connec-

tors during installation and use. Although

there are normally no sharp edges, care

must be taken when handling certain compo-

nents to avoid injury to fingers. Electrical

connectors may be damaged in transit to the

customers, and damage may result in cre-

ation of hazards. Products should therefore

be examined 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 circuit, because an elec-

tric 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 cannot be trans-

mitted 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 lubricants, swarf, or any other

undesired conducting particles. Circuit resist-

ance and continuity check should be made to

make certain that there are no high resist-

ance joints or spurious conducting paths.

Always use the correct application tools as

specified in the Data Sheet/Catalog. Do not

permit untrained personnel to wire, assemble

or tamper with connectors. For operation

voltage please see appropriate national reg-

ulations.

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 applicable 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, Cannon products

may deviate from the description, technical

data and shape as shown in this catalog and

data sheets.
