2 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.
3 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.
Caution
Do not attach grounding cables to the ODU mounting bracket bolts, as this
arrangement will not provide full protection.
