[. . . ] c) If an optional Breather/Drain as listed on the enclosure certificate is fitted the enclosure must be sited such that the Breather/Drain is pointing vertically downwards from the bottom of the box, and the IP rating of the selected Breather/Drain shall match the IP rating of the enclosure. d) The enclosure may be ready supplied with cable entries. Where the customer drills cable entries they must be installed in accordance with the component certificates 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). g) When document pocket is fixed to the inside of the lid, care must be taken by installer / end-user to prevent static build-up i. e. plastic wallets must not be used to contain documents. 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/EN 61241-0 and IEC/EN 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. A parallel shaft screwdriver of the correct size should be used. D9160 terminal schedule may be incorporated in the box. The installer must ensure that the conditions of use for the terminals outlined are complied with. g) All terminal screws used and unused shall be fully tightened down. [. . . ] Note : There is an integral connection from the internal earth connection through to the external of the box.
