oec NOTE 1 At ambient temperature equal to ULT, the available temperature rise due to current flow is zero, thus the current carrying capacity of the connector is zero.
It may also provide other functions such as earthing, bonding, insulation, cable guarding, strain relief or a combination of these. In the case of contact elements, a mating pair of the intended coupling elements 3. Values for these characteristics shall be specified in conjunction with mechanical and environmental conditions given in the detail specification or in the manufacturer’s specification, where no detail specification exists.
Compliance with this requirement is verified by the specified tests of this 619984. Markings a and b of 6. All markings of 6.
Examples of markings for rated current, rated ief, rated impulse voltage and pollution degree: Marking of the first contact and first row by a letter, number or another clear symbol is sufficient. This requirement does not apply to a connector in which contact identification is ensured in the end-use product. Relevant information shall be given in the technical documentation of the manufacturer.
Marking of protective earthing 16984 shall apply the symbol or PE. This requirement is not necessary for non rewirable connectors. Marking shall not be applied to screws or other removable parts. Symbols are given in IEC The symbol is reserved for end-use-equipment. The protection class of components is dependent upon the equipment in which they are used.
ief Therefore, components shall not be marked with the symbol. Compliance is checked by a polarisation test. All parts which are necessary to ensure protection against electric shock shall only be removable by the aid of a tool.
This requirement does not apply to a connector in which protection against electric shock is ensured by its mounting provisions or by the use of safety extra-low voltage SELV, according to IEC in the end-use product. NOTE For an unenclosed connector, the protection against electric shock is provided by the enclosure of the equipment in which the connector is mounted, in accordance with the applicable product safety standard.
If protection is claimed by the manufacturer, the requirements of 6. Compliance is checked in accordance with Clause 5 of IEC NOTE If accessible metal parts are screened from live parts by metal parts which are connected to an earthing terminal or earthing contact, or if they are separated from live parts by double or reinforced insulation, they are not, for lec purpose of this requirement, regarded as likely to become live in the event of an insulation fault.
Compliance is checked by the test of 7. Table 2 — Compliant 69184 and connection methods Ref. Table 3 — Tests on connections and terminations Ref.

The dimensional test is carried out according to IEC The compliance check of dimensions is the verification of the safety of the connection according iwc IEC If the dimensions do not comply with the specification, the test is not met. Flat, quick-connect terminations, which are definitely not designed according to IEC can be used if the test iwc according to IEC is met.
Electrical and thermal tests on lec shall be carried out in conjunction with the test 6198 the connector. Other terminations and connection methods have to be tested in accordance with the relevant standards.
On the basis of the tests according to IEC or IEC of Table 3, insulation piercing connections are excluded from the above requirement. NOTE If pilot contacts last make, first break contacts are used for the electrical interlock, these can be live when disengaged if the pilot contacts are protected against indirect contact with live parts.
This requirement does not apply to connectors for example two-part connectors for printed boards and rack-and-panel connectors where mismating is prevented by their mounting provisions or by additional accessories, if necessary and available. Besides the termination of the conductor, care shall be taken that no damage of the insulation is possible, e.

NOTE 2 Connectors with non-rewirable terminations e. If this cannot be granted by the design or manufacturing process itself, the in-process test 6198 according to 7. The connector shall withstand the test voltage specified in Table 8, in accordance with 7.
Compliance shall be checked by the test of 7. Tensile and torsion requirements shall be as specified in Table 6. Loose parts inserted to obtain clamping of the cable are permitted if they are fixed in the connector in the assembled state.
The cable clamp can be made of insulating material or metal. If it consists of metal, it shall meet one of the following requirements: Clearances through slots and openings in enclosures of insulating material shall meet the values of case A of Table F.
If the rated voltage is not derived from the nominal voltage of the supply system see Table F. For the relationship between creepage distance and clearances see 5. For a connector with a degree of protection IP54 or higher according to IECthe insulating parts inside the enclosure may be dimensioned for a lower pollution degree.
This lower pollution degree also applies to mated connectors where the enclosure is ensured by the connector housing and which may only be disengaged for test and maintenance purposes.
NOTE The pollution degree strongly influences the rated insulation voltage of a connector. Therefore, the rated insulation voltage for a connector with creepage distances fixed by design should be reconsidered for each pollution degree separately. If the height of the ribs is at least 2 mm the creepage distances may be dimensioned in accordance with one insulating material group level lower.
If the associated clearance, measured on the component, is less than 3 mm, the minimum groove width may be reduced to one-third of this clearance. In all other cases, the groove walls shall not be 6194 into account. Methods of measuring clearances and creepage distances are given in 6. It shall not be possible to remove the supplementary insulation without using a tool. For double insulation, where basic and supplementary insulation cannot be tested separately, the insulation system shall be considered as reinforced insulation.
The creepage distances shall be doubled in comparison with the basic insulation. For each test group, a separate set of 69184 specimens shall be used.
