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

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.

2. FIRE CHARACTERISTICS AND ELECTRIC

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.

3. HANDLING

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.

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.

4. DISPOSAL

Incineration of certain materials may release

noxious or even oxid fumes.

5. APPLICATION

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.

Always use the correct application tools as specified

in the Data Sheet/Catalogue.

Do not permit untrained personnel to wire, assemble

or tramper with connectors.

For operation voltage please see appropriate national

regulations

IMPORTANT GENERAL INFORMATION.

1. Air and creepage paths/Operating voltage

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.

2. Temperature

All information given are temperature limits. The

operation temperature depends on the individual

application.

3. Other important information

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.

4. Harnessing and Assembly Instructions

If applicable, our special harnessing and/or assem-

bly instruction has to be adhered to. This is provid-

ed at request.
