Installing the ODU and top LPU
Attach ground cables to the ODU
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.
Tighten both ODU grounding bolts to a torque of 5.0 Nm (3.7 lb ft).
Mount the ODU on the mast
Select the most appropriate bracket mounting arrangement from the options listed in
on page 16. Refer to individual procedures below for each of the options:
•
Tilt Bracket Assembly
•
Tilt Bracket Assembly with band clamps
•
Mounting bracket (Integrated)
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
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.
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.
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.
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.
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.
