Lightning protection unit (LPU) and grounding kit
450i and 450m Series LPUs provide transient voltage surge suppression for ODU installations. Each
cable requires two LPUs, one near the ODU and the other near the linked device, usually at the building
entry point (
).

One LPU and grounding kit (
) is required for the PSU drop cable connection to the ODU. If the
ODU is to be connected to an auxiliary device, one additional LPU and grounding kit is required for the
Aux drop cable. Order the kits from Cambium Networks (
