[. . . ] No more than one single or multi-stranded lead shall be connected to either side of any terminal unless multiple conductors have been joined in a suitable manner e. g. two conductors into a single insulated bootlace ferrule, or any method indicated on the terminal schedule. Terminals shall be installed in such a manner that the creepage and clearance distances between the terminal and adjacent components, enclosure walls and covers comply with the requirements of IEC 60079 for the rated voltage of the equipment. Terminal temperatures must not exceed the operating range specified on the component certificate. All terminals and accessories such as cross-connectors shall be installed in accordance with the terminal manufacturer's instructions. The maximum voltage, current and dissipated power shown on the rating label must not be exceeded. When connecting conductors of cross-section below the maximum allowed for the particular terminal then the maximum amps per pole must be reduced in line with the maximum amps permitted for a terminal equivalent to the conductor size fitted e. g. if a terminal that can take a 10mm² conductor at 40 amps is fitted with a 4mm² conductor then the current shall be reduced to a maximum of 22 amps or the rating marked on the apparatus label whichever is the lower. When label fixing is by screws complete with Nyloc nuts, then the ingress protection is IP66. Carefully remove the lid ensuring the gasket is not displaced or damaged. TO CLOSE THE LID: 1. Check that the gasket is correctly located in the groove in the underside of the lid and undamaged. EARTHING: a) Junction boxes shall be earthed in accordance with the relevant code of practice e. g. ii) The PJB 1 box may be supplied fitted with or without an internal earth continuity plate. Note : An optional internal / external earth stud is available. ENCLOSURE INSTALLATION (EI) a) The IP rating of the enclosure must be maintained for the area of use (e. g. IP6* for Zone 21 dust environment) by the use of correct arrangement of cable/gland/sealing arrangements and in accordance with the installation codes as detailed in IEC/EN 60079-14, IEC/EN 61241-14 and these installation instructions. Where the customer drills cable entries they must be installed in accordance with the component certificate and enclosure limitations, these specify a maximum clearance on the entry thread of 0. 7mm for plain holes and where adjacent cable entries are installed sufficient clearance must be maintained to allow for the fitting of sealing/retaining washers and the rotation of the cable gland hexagons, and leave a minimum of material between adjacent holes in line with the above certificate number(s). TERMINAL WIRING (TW) a) All wiring must be carried out in accordance with the relevant code of practice and/or instructions e. g. [. . . ] The terminal cap of each terminal, used and unused, shall be fully tightened down by the end user. Conductors of different sizes and configurations shall not be inserted into the same terminal throat/slot except for the specific combinations listed in Tables 1 & 2. When installed in an enclosure the creepage and clearance distances between the terminals, adjacent equipment and enclosure walls must comply with the requirements of IEC/EN 60079-7. [. . . ]
