[. . . ] Pass the brass pot over the spigot and remove any surplus compound from the top of brass pot and the joint face as indicated. H Replace the entry over the brass pot ensuring that compound does not cover the end of . I Locate and hand tighten the sub-assembly and onto the entry . Unscrew the sub-assembly and from the entry then remove any surplus compound from the gland components. Again locate and hand tighten the sub-assembly and onto the entry . IMPORTANT: The conductors must not be moved for a minimum of four hours. AI 318 / AI 339 - Issue L / Page 2 of 4 6 5 6 2 2 1 1 J Allow the compound to cure. Untighten the sub-assembly and from the entry . Check that the compound has cured. K Hand tighten the sub-assembly and onto the entry and add half to three quarters of a turn with a spanner/wrench. Tighten the backnut to form a seal around the cable, then tighten a further full turn using a wrench/spanner. Ensure that the middle nut does not rotate when tightening the backnut. Ensure that the deluge seal is pulled down into position, if fitted. Locate the shroud over the cable gland, if applicable. The following instructions are the approved methods of passing drain wires etc. through the compound barrier and should be followed if permitted by cable installation specifications. UNINSULATED EARTH OR DRAIN WIRE PREPARATION 1. 0 INSULATING EARTH OR DRAIN WIRES WITH HEAT SHRINK OR COLD SHRINK TUBING 1. 1 Fold back the armour and bend it to right angles from the inner sheath. 1. 2 Remove foils and tape level with the outer sheath, exposing the uninsulated earth or drain wires and insulated conductors. Cut back a further 10mm of inner sheath. 1. 3 Pass 100mm length of heat shrink or cold shrink tubing over the uninsulated earth or drain wire until it comes into contact with the foils, then shrink the tubing evenly down onto the uninsulated earth or drain wire so that no air pockets occur. 1. 4 To insulate the joint between the foils and the tubing a suitable piece of 10mm long shrink tubing or neoprene stretch tubing or a 10mm wide lap of PVC tape may be used. 1. 5 After completing 1. 1 to 1. 4 on each earth or drain wire, lay the armour parallel to the cable, if applicable, then carry out instruction B. INDIVIDUAL SHIELDING OR SCREEN PREPARATION 2. 0 INSULATING SCREENS WITH HEAT SHRINK OR COLD SHRINK TUBING 2. 1 Fold back the armour and bend to right angles from the inner sheath. 2. 2 Remove a further 15mm of inner sheath (See Fig. 2. 3 Unravel one or two groups of wires from the individual shielding or screen wires, then remove the remainder of the individual shielding or screen wires (See Fig. 2) and twist the wires along their full length. 2. 4 Pass 100mm length of heat shrink or cold shrink tubing over the individual shielding or screen until it comes into contact with the foils, then shrink the tubing evenly down onto the individual shielding or screen so that no air pockets occur. 2. 5 To insulate the joint between the individual shielding or screen wires and the tubing, place one lap of PVC insulating tape over the exposed metallic joint. 2. 6 After completing 2. 1 to 2. 5 on each individual shielding or screen, lay the armour parallel to the cable. Then carry out instruction B. Armour Inner Sheath Shielding Screen Wires One or two groups of shielding screen wires Fig. [. . . ] A grounding / earth tag has been provided for use as a grounding point when the cable gland is used with plastic enclosures. This must be fitted to the wall of the enclosure using the threads of the gland and the locknut supplied. Note: Grounding must be carried out in accordance with National Electrical Code Article 250 and 505. 25. A correctly sized grounding conductor must be connected from the tag to the nearest internal connection point of the grounding circuit. [. . . ]
