[. . . ] Spread braid over the spigot until the end of the braid is up against the shoulder of the spigot. Position the clamping ring . C Remove the brass pot from the entry . Place the entry over the spigot Move the sub-assembly and up to meet the entry . Note: If the equipment has a threaded entry it may be advisable to screw the entry component into the equipment to prevent twisting of the cable after step D AI 373 - Issue B / Page 1 of 4 Sales (UK): 0870 606 0105 Sales: +44 (0) 161 830 6698 Technical (UK): 0870 458 9358 Technical: +44 (0) 161 830 6697 Fax: +44 (0) 161 830 6648 E-mail: sales@ehawke. com Safety First Hawke International is a division of Hubbell Ltd. [. . . ] Unscrew the sub-assembly and from the entry then remove any surplus compund from the gland components. IMPORTANT NOTE: The conductors must not be moved for a minimum of four hours. AI 373 - Issue B / Page 2 of 4 6 5 6 2 2 1 1 J Allow the compound to cure. 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. 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. 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. 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. 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.

If such vapours are likely to be present in the vicinity of the cable gland in service, suitable precautions may be necessary. (Contact Hawke's Technical Dept). 40 ºC 25 ºC 4 ºC The compound cures at a Shore D hardness of 85, when it can be handled. [. . . ] 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 373 - Issue B / 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.
