Hand tighten the middle nut to the entry and turn a further ½ to ¾ of a turn with a spanner/wrench. IMPORTANT: Support the cable to prevent it from twisting. 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. Note : If the equipment has a threaded entry, it may be advisable to screw the cable gland into the equipment to prevent twisting of the cable after Step E F Select the correct punch tool to suit the conductors sizes (see table) and cut out the required number of holes in the seal using the indented positions as a guide. Remove the entry and pass the individual conductors through the appropriately sized punched holes in the seal ensuring they are not twisted or kinked, and slide the seal down to the spigot . Replace entry and re-assemble middle nut onto the entry component . Tighten up the middle nut until hand tight, then using a wrench/spanner turn the nut through a minimum of one full turn. 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. CABLE GLAND SELECTION TABLE Size Ref.
