Connections shall be made in a manner consistent with the type of terminal,
type of protection and not introduce undue stress on the connections.
If multi-stranded and, in particular, fine-stranded conductors are employed,
the ends shall be protected against separation of the strands, e.g., by means
of cable lugs, core-end sleeves or by the type of terminal, but not by soldering
alone.
Unused cores
The hazardous area end of each unused core in multi-core cables shall either
be connected to earth or be adequately insulated by means of terminations
suitable for the type of protection.
The external circuit breaker must be provided by the customer as
part of the equipment installation and shall meet the relevant
requirements of IEC 60947-1 and IEC. This switch or breaker
must be suitably located and easily reached (within 3 meters).
Insulation of multi-core cables by tape alone is not permitted.
The creepage distances and clearances shall not be reduced by
the method in which the conductors are connected to the
terminals.
