Installing the ODU and top LPU
Attach ground cables to the ODU
1
Fasten one ground cable to each ODU grounding point using the M6 (small) lugs: one is for the
top LPU (M6 lug at other end) and the other is for the tower or building (M10 lug at other end).
It does not matter which cable goes on which ODU grounding point.
2
Tighten both ODU grounding bolts to a torque of 5.0 Nm (3.7 lb ft).

The mounting procedures can be adapted to attach the ODU to a suitable horizontal pole, but the
adjustment of azimuth angle is necessarily limited compared with an installation on a vertical pole.
Tilt Bracket Assembly
1 Fix the mounting plate of the Tilt Bracket to the back of the ODU using four of the short bolts,
ensuring that the arrow in the plate points towards the top of the ODU. Tighten the four bolts to
a torque setting of 5.0 Nm (3.7 lb ft) using a 13 mm spanner or socket.
2 Fit the two long bolts through the bracket body so that the bolt heads engage in the slots as
shown. Fit two of the short bolts into the side of the bracket body but do not tighten.
3 Thread two of the nuts to the long bolts and tighten against the bracket body using a 13 mm
spanner. Fit the bracket strap and thread the remaining nuts onto the long bolts.
4 Fix the assembled bracket body to the pole, adjust the azimuth angle, and tighten the nuts to a
torque setting of 10.0 Nm (7.4 lb ft) using a 13 mm spanner, ensuring that the arrow in the body
is pointing upwards.
5 Hoist the ODU to the mounting position. Fit the mounting plate to the bracket body by
positioning the open-ended slots over the short bolts. Insert the remaining short bolts through
the longer curved slots into the threaded holes in the bracket body. Adjust the elevation angle,
and tighten the bolts to a torque setting of 8.0 Nm (5.9 lb ft) using a 13 mm spanner or socket.
