Cable grounding kit
Copper drop cable shields must be bonded to the grounding system in order to prevent lightningstrike arcing
(resulting in fire risk and damage to equipment).
One grounding kit ( Figure 17 ) is required for each grounding point on the PSU. Order cable grounding kits from
Cambium Networks ( Table 36 ).
Caution
To provide adequate protection, all grounding cables must be a minimum size of 10
