[. . . ] Hand tighten the middle nut onto the entry and turn a further half to three quarters of a turn with a spanner/wrench. E Unscrew the middle nut and visually inspect that the armour/braid has been successfully clamped between the armour spigot and the armour clamping ring . If armour/braid not clamped repeat assembly. F Remove the entry , spread the cable cores out for the compound packing. Pack the compound between the cores shown. 7 for compound preparation. EPOXY COMPOUND PREPARATION When handling this material, the gloves supplied must be worn. [. . . ] Hand-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. Ensure that the deluge seal is pulled down into position, if fitted. Locate the shroud over the cable gland, if applicable. 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. Armour / braid Inner Sheath Screen Wires One or two groups of screen wires 2. 0 Fig. 3 Crimp or Insulated Solder Conductor INSULATING DRAIN WIRES WITH INSULATING VARNISH OR PAINT 3. 1 Fold back the armour / braid and bend it at right angles from the inner sheath. 3. 2 Remove the foil and tape level with the inner sheath exposing the drain wires and conductor pairs. 3. 3 Cut back a further 10mm of inner sheath (See Fig. [. . . ] These glands are suitable for use temperature range temperature range of -60°C to +80°C. A seal must be formed between the equipment and the cable gland to 2. When the gland is used for increased safety, the entry ingress shall be maintain the appropriate degree of protection against thread of dust, solid objects and water. the ingress protection rating of the associated suitably sealed to maintain enclosure.
