1.
Strip the cable to suit equipment and expose armour/braid.
2.
Push the cable through the diaphragm shield/armour spigot (4). Pre-fitted cable
guide (4.1) can now be discarded. The diaphragm seal can be rolled back to ease
assembly as required. Spread armour/braid over the diaphragm seal/armour spigot
(4) until the end of the armour/braid is up against the shoulder of the armour cone.
Position the armour clamping ring (3).
3.
Place the entry (5) and position over the diaphragm seal/armour spigot (4). Move the
sub-assembly (1) and (2) up to meet the entry (5).
4.
Hold the entry (5) in position with a wrench to prevent rotation. Hand tighten the
middle nut (2) to the entry (5), and turn a further 1/2 to 3/4 turn with a wrench.
Note:
Support the cable to prevent it from twisting. To ease the wiring inside the
enclosure, it may be beneficial to strip the inner sheath of the cable.
5.
Unscrew the middle nut (2) and visually inspect that the armour/braid has been
successfully clamped between the diaphragm seal/armour spigot and the armour
clamping ring (3). If armour/braid is not clamped, repeat assembly. (Armour/braiding
should be fitted 360 degrees around the entry.)
6.
Reassemble the middle nut (2) onto the entry component (5). Tighten up the middle
nut (2) until hand tight, then using a wrench, turn the nut through 1/4 turn. Tighten
the backnut (1) to form a seal around the cable, then tighten a further full turn using
a wrench. Ensure that the middle nut (2) does not rotate when tightening the
backnut (1).
Note:
The deluge seal on this gland locates on assembly and requires no further
action. Locate shroud over cable gland, if applicable.
