Installing the ODU Chapter 5: Installation
5-6 phn-2510_002v000 (Mar 2012)
Mounting the ODU
To mount the ODU, proceed as follows:
1
Attach the ODU bracket strap to the pole using M8 x 40 mm or M8 x 70 mm bolts,
M8 flat washers and M8 coil washers.
Tighten to ensure the assembly grips, but can be adjusted on the pole.
2
Use the integral safety loop ( Figure 22 ) to hoist the ODU up to the bracket,
observing the precautions described in Checks and safety precautions on page 5-4 .
3
When the ODU is in position, use the safety loop as a fixing point to secure a
permanent safety lanyard from the supporting structure to the ODU, as a
precaution against mounting failure.
4
Offer the ODU (with pre-fitted mounting bracket) to the bracket strap and affix
using the captive M8 bolt. Tighten to ensure the assembly grips, but can be
adjusted on the pole.
5 Adjust the elevation and azimuth of the unit to achieve an approximate visual
alignment (does not apply to connectorized ODUs). Tighten both bolts to the
required torque settings of 14 Nm (11 lb ft).
Do not over-tighten the bolts, as this may lead to failure of the assembly.
