Chapter 5: Installation

Ground the ODU and top LPU

Caution
Do not attach grounding cables to the ODU mounting bracket bolts, as this
arrangement will not provide full protection.
1 For separate LPU mounting, use the U-bolt bracket from the LPU kit to mount the top LPU on the
pole below the ODU. Tighten to a torque setting of 7 Nm (5.5 lb ft):
2 Fasten the ODU grounding cable to the top LPU using the M6 (small) lug. Tighten both nuts to a
torque of 5 Nm (3.9 lb ft):
3 Select a tower or building grounding point within 0.3 meters (1 ft) of the ODU bracket. Remove
paint from the surface and apply anti-oxidant compound. Fasten the ODU grounding cable to this
point using the M10 (large) lug.
4 If local regulations mandate the independent grounding of all devices, add a third ground cable to
connect the top LPU directly to the grounding system.
