Step 5.
Tighten the joint pack assembly using a 19mm spanner until the
shear nut breaks and the indicator disk drops off then tighten
to 65Nm ±5Nm using a calibrated torque wrench with a 19mm
socket. If installed correctly the joint will appear level and no
overlapping should appear. If overlapping of the Expansion
Ribs is apparent then the joint is not installed correctly.
The shear nut will break when torqued to 65Nm ±5Nm in a
clockwise direction. This will cause the indicator disc to fall off.
Step 6.
Megger the installed joint pack to ensure it is fi tted correctly.
Following a visual inspection to ensure that there are no
anomalies such as foreign material etc, install the front
joint pack cover.
Joint pack cover

prior to installation.
Step 1.
Mount Busbar to frame.
Step 2.
Install the Joint Pack Elbow to Busbar, never force the joint
or strike it with any object as this may damage the Joint or
Busbar section. The joint should be inserted by means of
a constant force, i.e. pushing in by hand or by means of a
suitable clamping arrangement.
Step3.
Position second busbar as shown in image overleaf. Ensure
the Earth Side Plates are not over lapping the Expansion Ribs.
The Earth side plates should sit approx 2mm back from the
Expansion Rib when positioned correctly.
Step 4.
Mount the second Busbar section fi rmly to the frame work.
Step 5.
Attach the rear Joint Pack Cover to Parts.
Step 6.
Tighten the Joint Pack assembly to the correct torque level
(65Nm ±5Nm). If installed correctly the joint will appear
level and no overlapping should appear. If overlapping of
the Expansion Ribs is apparent then the Joint is not installed
correctly.
Step 7.
Megger the installed joint pack to ensure it is fi tted correctly.
This is on a visual inspection for any anomalies such as
foreign material etc. Now attach the front Joint Pack Cover to
the Busbar.
