These notes are intended to be used in conjunction with the Product
Catalogue and Product Specification. Products may be safely used in the
applications for which they have been designed and within the specified
ratings and environments. If products are exposed to conditions outside
the performance ratings or specified environments they may constitute a
hazard. In particular it should be noted that:
1 . Material Content
Circular Connectors generally use metalwork parts made of brass,
aluminium, phosphor-bronze or steel, which, dependent on the particular
application, may be passivated and protected with cadmium or zinc plate
- in conjunction with chromated or anodised surface finishes. The
insulating materials can either be natural or synthetic rubber, together
with plastic or glass-filled plastic moulded parts. Contact materials
vary but are usually made of brass, phosphor-bronze, alumel or chromel.
2. Electric Shock, Burns and Fire
Hazard can occur if the product is used outside the specified parameters
or if the product is damaged, wrongly wired or poorly assembled, or
poorly integrated into larger equipments, or contaminated with
conductive fluids. Live circuit terminations must be protected and live
circuits never broken by disconnecting products.
Hot spots may be created when resistance is increased due to damage or
incorrect integration particularly soldering, or loose terminations.
Overheating can cause breakdown of insulation, electric shock, burns or,
ultimately, fire. In the event of fire noxious and/or toxic fumes may be
released and, in these circumstances, any fire involving the product
should be dealt with by personnel properly equipped. Connectors with
exposed terminations or contacts should not be used on the current
supply side of a circuit with exposed contacts on an unmated product.
Before making a circuit live, the product and wiring should be checked
to ensure there is no electrically conducting debris present. Circuit
resistance checks should also be conducted before making the circuit
live. Always ensure that connectors are assembled and wired by properly
trained personnel. .
3. Use, Transport and Storage of
Products
Care must be exercised to avoid damage to any part of the products
during transporting, storage or use. Abnormal transit or storage
conditions and abuse during installation can give rise to damage.
Products should not be used in a damaged condition.
Improper storage (particularly of damaged products) can give rise to
additional hazards particularly corrosion. Your attention is
specifically drawn to the need for proper storage of products containing
cadmium and you are advised to see the Guidance Note from the Health and
Safety Executive on Cadmium - Health and Safety Precautions.
4. Disposal of Products
Products should not be burnt.
SAFETY RULES
1. FOLLOW THE GUIDELINES GIVEN.
2. ALWAYS PROTECT LIVE CIRCUITS AND NEVER DISCONNECT A LIVE CONNECTOR.
3. NEVER USE A DAMAGED CONNECTOR.
4. NEVER BURN DISCARDED CONNECTORS.
