Product Safety Information
Fire can then result in the presence of
combustiblematerialsandthismay release
noxious fumes. Overheating may not be
visually apparent. Burns may result from
touching overheated components.
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
resultincreationofhazards.Productsshould
therefore be examined prior to installation/
use and rejected if found to be damaged.
DISPOSAL
Incinerationofcertainmaterialsmayrelease
noxious or even toxic fumes.
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
exposedcontactsonanunmatedconnector.
Voltages in excess of 30 V ac. or 42.5 V dc
are potentially hazardous and care should
betakentoensurethatsuchvoltagescannot
betransmittedinanywaytoexposedmetal
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.
Insulation resistance should be checked to
make certain that no low resistance joints
or spurious conducting paths 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 tamper with connectors.
For operation voltage please see
appropriate national regulations.
IMPORTANT GENERAL INFORMATION
(i) 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 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
ITT Industries continuously endeavours to
improve their products. Therefore, ITT
Industries products may deviate from the
description,technicaldataandshapeasshown
in this catalog and data sheets.
(iv) Harnessing and Assembly Instructions
If applicable, our special harnessing and/or
assembly instruction has to be adhered to.
This is provided on request.

MATERIAL CONTENT AND PHYSICAL FORM
Electricalconnectorsdonotusuallycontain
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,FireBarrierandHighReliability
types withmetalcasingsandeithernatural
rubber, synthetic rubber, plastic or glass

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.
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 not 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
whenresistanceisraisedlocallybydamage,
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.
Ifheatingisallowedtocontinueitintensifies
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.
