7.2.1 If the module contains a field wiring terminal block, it shall be rated for the appropriate voltage and current for the application and constructed in compliance with the requirements of IEC 60947-1 .
7.2.2 If the module alternately contains wiring terminals integral to the construction of the terminal enclosure, they shall comply with the following requirements:
7.2.2.1 Screws and nuts which clamp external conductors shall have a thread conforming with ISO 261 or ISO 262, or a thread comparable in pitch and mechanical strength (e.g.standard threads). The screws and nuts used for field wiring shall not serve to fix any other component. These connections are also permitted to clamp internal conductors provided that the internal conductors are so arranged that they will not be displaced when fitting the external conductors.
7.2.2.2 Terminal screws shall have minimum sizes as shown in Table 2. Stud terminals shall be provided with nuts and washers.
7.2.2.3 Terminals shall be so designed that they clamp the conductor between metal surfaces with sufficient contact pressure and without damage to the conductor. Terminals shall be so designed or located that the conductor cannot slip out when the clamping screws or nuts are tightened. Terminals shall be so fixed that, when the means of clamping the conductor is tightened or loosened:
a) the terminal itself does not work loose,
b) internal wiring is not subjected to stress,
c) creepage distances and clearances are not reduced below the values specified in Clause 9.
7.3.1 A connector intended for use in the output circuit of a module shall be rated for the appropriate voltage and current, as per the requirements of the IEC 601 30 series. In addition, the connector shall comply with the requirements of Clause 5, with respect to flammability, comparative tracking index and relative thermal index for the support of live parts.
7.3.2 Unless a connector is appropriately evaluated for disconnect overload performance, the connector shall be assumed to be suitable for assembly only and not reliable as a disconnect means. See Clause 11.
