[. . . ] Pass the rubber pot over pot cap and remove any surplus compound from the top of rubber pot and joint faces as indicated. 5 4 3 2 2 1 1 1 5 2 G To further locate and support the compound and rubber 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. H Allow the compound to cure. Untighten firstly the backnut from and secondly the middle nut from the entry . The rubber pot may be removed for inspection to ensure that the packing is satisfactory. [. . . ] 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. Only compound for immediate terminations should be mixed. The mixing and installation of the compound at an ambient temperature below 4°C is not recommended due to extended curing period The following instructions are the various BASEEFA approved methods of passing drain wires etc. through the compound barrier and should be followed if permitted by cable installation specifications. DRAIN WIRE PREPARATION 1. 0 INSULATING 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 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 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. 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 drain wire, lay the armour / braid parallel to the cable, if applicable, then carry out instruction B. INSULATING DRAIN WIRES / SCREENS WITH SEPARATE INSULATED CRIMPED CONDUCTORS OR SOLDERED CONNECTION 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 screen wires, then remove the remainder of the screen wires (See Fig. 2. 4 Twist the group of screen wires into a pigtail and cut to 15mm long. 2. 5 Crimp an insulated conductor to the pigtail wih a suitable insulated butt ferrule (or soldered connection), leaving enough length of the insulated conductor to enable the remote end to be connected to the earth terminal in the equipment. Note: There shall be a minimum of 10mm of compound on both ends of the crimped / soldered joint. 2. 6 To insulate the joint between the screen wires and the insulated conductor, place one lap of PVC insulating tape over the exposed metallic joint. 2. 7 After completing 2. 1 to 2. 6 on each drain wire, lay the armour / braid parallel to the cable.
