[. . . ] Again locate and hand tighten the sub-assembly and onto the entry To further locate and support the compound and brass pot assembly, while holding the middle nut with a spanner / wrench, tighten the backnut until the seal grips the cable to prevent movement of the cable gland. IMPORTANT NOTE: THE CONDUCTORS MUST NOT BE MOVED FOR A MINIMUM OF FOUR HOURS I Allow the compound to cure. Untighten firstly the backnut from and secondly the middle nut from the entry Check that compound has cured. [. . . ] Ensure that the middle nut does not rotate when tightening the backnut Ensure that the deluge seal is pulled 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 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. 2. 4 After completing 2. 1 to 2. 3 on each shielding or screen wire. 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. 40 ºC 25 ºC 4 ºC The compound cures at a Shore D hardness of 85, when it can be handled. The compound when fully cured is uitable for use at a temperature range of -50°C to +60°C. Fig. [. . . ] 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. When the gland is used with enclosures having plain (strikethrough/drilled) entry holes, a UL listed (QRCV) sealing washer must be employed and the gland must be secured to the enclosure using the locknut provided.
