PTP 670 QUICK START GUIDEPAGE 17Installing the ODU and top LPUAttach ground cables to the ODUFasten one ground cable to each ODU grounding point using the M6 (small) lugs: one is for the top LPU (M6lug at other end) and the other is for the tower or building (M10 lug at other end). It does not matter whichcable goes on which ODU grounding point.Tighten both ODU grounding bolts to a torque of 5.0 Nm (3.7 lb ft).1 2Mount the ODU on the mastSelect the most appropriate bracket mounting arrangement from the options listed in Mounting bracket optionson page 16. Refer to individual procedures below for each of the options: Tilt Bracket Assembly on page 17 Tilt Bracket Assembly with band clamps on page 18 Mounting bracket (Integrated) on page 19The mounting procedures can be adapted to attach the ODU to a suitable horizontal pole, but the adjustment ofazimuth angle is necessarily limited compared with an installation on a vertical pole.Tilt Bracket AssemblyFix the mounting plate of the Tilt Bracket to the back of the ODU using four of the short bolts, ensuring thatthe arrow in the plate points towards the top of the ODU. Tighten the four bolts to a torque setting of 5.0Nm (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 twoof 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. Fitthe 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 torquesetting of 10.0 Nm (7.4 lb ft) using a 13 mm spanner, ensuring that the arrow in the body is pointingupwards.Hoist the ODU to the mounting position. Fit the mounting plate to the bracket body by positioning theopen-ended slots over the short bolts. Insert the remaining short bolts through the longer curved slots intothe threaded holes in the bracket body. Adjust the elevation angle, and tighten the bolts to a torque settingof 8.0 Nm (5.9 lb ft) using a 13 mm spanner or socket.
