[. . . ] Untighten firstly the backnut from and with a spanner / wrench, tighten the backnut secondly the middle nut from the entry . until the seal grips the cable to prevent movement Check that compound has cured. of the cable gland. IMPORTANT: The conductors must not be moved for a minimum of four hours. AI 391 - Issue A / Page 2 of 4 I Hand tighten the sub-assembly and to the entry and add half a turn to with a spanner / wrench. Tighten the backnut to form a seal around the cable, then tighten a further half to full turn using a spanner / wrench. Ensure that the middle nut does not rotate when tightening the backnut . 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 Remove foils and tape level with the inner sheath, exposing the uninsulated earth or drain wires and insulated conductors. 1. 2 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. 3 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. 4 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 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. 2 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. 3 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. 4 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.

[. . . ] 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. The maximum constructional gap (Ic) of the cylindrical flamepaths are less than that required by Table 2 of IEC 60079-1 : 2003 (EN 60079-1 : 2004) as follows: 0. 083mm between compound pot and entry component bore. AI 391 - Issue A / Page 4 of 4 ACCESSORIES: Before cable gland assembly or stripping of the cable gland assembly, consideration should be given to any cable gland accessories that may be required, such as: Shroud, to offer additional corrosion protection.
