[. . . ] Where the customer drills cable entries they must be installed in accordance with the component certificates BAS01ATEX2105U, Baseefa 08ATEX0207U or IEC Ex BAS 08. 0064U 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 inline with the above certificate number(s). e) All unused entry apertures must be sealed using a stopping plug as listed on the enclosure certificate and also the IP rating of the junction box shall be maintained for the zone of use. f) The apparatus must not be modified in anyway without reference to Hawke, as this will invalidate the certification, except for EI d) and e) and TW j) and k). TERMINAL WIRING (TW) a) All wiring must be carried out in accordance with the relevant code of practice and/or instructions e. g. IEC/EN 60079-14, IEC 60079-14, EN61241-0, EN 61241-1, IEC 61241-0 and IEC 61241-1. b) The voltage and current and maximum dissipated power shown on the label must not be exceeded. c) When used as a general purpose junction box or marshalling box the circuits carrying currents 1A shall be individually protected against over current such that the protective device operates effectively at no more than 1. 45 times the current carrying capacity of the smallest conductor used in that circuit. d) Where a major portion of the terminals are carrying maximum rate current the temperature at the branching point of the conductors may exceed 70°C. Under these circumstances the installer must ensure that the limiting temperature for the cable insulation used is acceptable e. g. e) Not more than one single or multiple stranded lead shall be connected into either side of the terminals, unless the relevant component certificate allows more, or unless the multiple conductors have been previously joined in a suitable manner (for example with an insulated crimped boot lace ferrule, mounted in a vertical position) such that they form a single cohesive item for insertion into the terminal way. The installer must ensure that the conditions of use for the terminals outlined are complied with. h) The installer shall ensure creepage and clearance distances are not reduced, especially between intrinsically safe (is) and non-is circuits (e. g. i) The use of any cross connection devices between adjacent terminal ways shall be in accordance with the requirements of the relevant component certificate listed on Drg. j) Use of the terminal box at ambient temperatures below ­20°C is dependant upon the minimum service temperature of the terminals. k) When connecting a terminal with a conductor that is below the maximum cross section area shown for the terminal, then the maximum amps / pole must be reduced in line with the maximum amps indicated for a terminal equivalent to the conductor size being fitted e. g. for a terminal that can take a maximum conductor size of 10mm² at 40 Amps, but is fitted with a 4mm² conductor then the current shall be reduced to a maximum a 22 Amps, or the rating on the junction box lid label (whichever is the lowest).
