and designed to ensure a good ground connection. The glands used must be firmly
attached to, and in good electrical contact with, a metal structure grounded in accordance
with these recommendations.
Electrical continuity must be ensured along the entire length of all cable coverings,
particularly at joints and splices. In no case should the shielding of cables be used as the
only means of grounding cables or units.
Cable connections
All cable connections are shown on the applicable cable plan and interconnection
diagrams.
Where the cable plan shows cable connections outside an equipment box outline, the
connections are to be made to a plug or socket which matches the plug or socket on
that particular item of equipment.
Where two cables are connected in series via a junction box or terminal block, the
screens of both cables must be connected together but not grounded.
Cable terminations
Care must be taken to ensure that the correct terminations are used for all cable
conductors. All cable work has to be done according to IPC 620 standard or similar
standards.
Cable identification
Cable identification codes corresponding to the cable number shown in the cable plan
must be attached to each of the external cables. These identification codes should be
positioned on the cable in such a way that they are readily visible after all panels have
been fitted. In addition, each cable conductor should be marked with the terminal board
number or socket to which it is connected.
