Installing the ODU and top LPU
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):
Locking nut

M6 lug

Toothed washer
M6 lug to ODU
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.
