[. . . ] Tighten the screw through the hole in the lid to prevent accidental lid closure. Unscrew the lid prop screw until it clears the hole in the lid. Lift the lid and swing the lid prop back inside the box. Disconnect power (isolate all circuits). [. . . ] Where the customer drills cable entries they must be installed in accordance with the component certificate Baseefa 08ATEX0363U & IECEx BAS 08. 0124U 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. e) Unused entry holes shall be fitted with stopping plugs as specified in the empty enclosure certificate Baseefa08ATEX0363U. The operating temperature range of the enclosure is limited to that of the stopping plug fitted. 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 used under dust layers, the maximum depth should be no greater than 50mm. TERMINAL WIRING (TW) a) All wiring must be carried out in accordance with the relevant code of practice and/or instructions e. g. 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) 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 certification. 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. h) 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). Caution: Ensure that wiring does not interfere with the enclosure lid during opening and closing. i) Terminals shall be installed in such a manner that the creepage and clearance distances between the terminal and adjacent components, enclosure walls and covers complying with the requirements of EN 60079-7:2007 for the rated voltage of the equipment. AI 280 - Issue J / Page 2 of 3 j) Terminal temperatures must not exceed the operating range specified on the component certificate. k) All terminals and accessories such as cross-connectors, shall be installed in accordance with the terminal manufacturers instructions.
