[. . . ] UK www. ehawke. com 6 6 4 Compound 4 3 2 2 2 1 D Unless already screwed into the equipment hold the entry in position with a spanner/wrench to prevent rotation. Hand tighten the middle nut onto the entry and turn a further half to three quarters of a turn with a spanner/wrench. E Unscrew the middle nut and visually inspect that the braid has been successfully clamped between the spigot and the clamping ring . If braid is not clamped repeat assembly. F Remove the entry spread out the cable cores and the individual strands of uninsulated conductors for the compound packing. Pack the compound between the cores and strands shown. [. . . ] 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 / braid 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 / braid 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 / braid 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 / braid parallel to the cable. Then carry out instruction B. Armour / braid Inner Sheath Shielding Screen Wires One or two groups of shielding screen wires Fig. 2 Armour / braid Inner Sheath Foils Outer Sheath Fig. 3 10mm Earth or Drain Wire or Twisted Screen Fig. 4 Insulated Earth Drain Wire or Twisted Screen Fig. 5 Sleeving AI 373 - Issue B / Page 3 of 4 Epoxy Compound Cure Time Vs. [. . . ] During periodic inspections the cable glands should be checked externally for tightness and visually inspected for any harmful corrosion. Cable gland installation work should not be carried out on live circuits. SCHEDULE OF LIMITATIONS: 1. The cable glands shall only be used where the temperature at the point of entry, is between -60°C to +80°C or -50°C to +60°C (as marked on the product). The entry thread shall be suitably sealed, in accordance with the applicable installation code of practice, to ensure that the ingress protection and restricted breathing sealing standards are maintained.
