User manual HAWKE 711 EXT D ASSEMBLY

[. . . ] Tighten the middle nut onto the entry component with a spanner/wrench until the grounding ring assembly grips the metal clad sheath. Then tighten the middle nut an extra half turn with a spanner/wrench. Connection Solutions Hawke International is a division of Hubbell Ltd. Registered Office: Mitre House, 160 Aldersgate Street, London EC1A 4DD. [. . . ] Should any compound come into contact with the skin it should be cleaned off with skin cleaner and not allowed to dry on the skin. The mixing and installation of the compound at an ambient temperature below 5°C is not recommended due to extended curing periods. J Hand tighten the sub-assembly and onto the entry and add full 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 metal armour, 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 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 uninsulated earth or drain wire, then carry out instruction B. INDIVIDUAL SHIELDING OR SCREEN PREPARATION 2. 0 INSULATING SHIELDING OR SCREENS WITH HEAT SHRINK OR COLD SHRINK TUBING 2. 1 Unravel one or two groups of wires from the shielding or screen wires, then remove the remainder of the screen wires (See Fig. 2. 2 Pass 100mm length of heat shrink or cold shrink tubing over the shielding or screen until it comes into contact with the foils, then shrink the tubing evenly down onto the drain wire so that no air pockets occur. 2. 3 To insulate the joint between the shielding or screen wires and the tubing, place one lap of PVC insulating tape over the exposed metallic joint. 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. The compound cures at a Shore D hardness of 85, when it can be handled. The compound when fully cured is suitable for use at a temperature range of -60°C to +80°C. Fig. [. . . ] 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 389 - 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.
