Installing the ERU
4
Estimate the amount of cable required for each of the following:
Cable run Distance
One hybrid RG-6/U coaxial cable with messengered
#17 AWG copper-clad steel grounding wire
This cable, which has a grounding wire attached, runs
from the ERU to the ground block.
One RG-6/U coaxial cable
This second piece of coaxial cable (no grounding wire
attached) runs from the ground block to the SOMAport.
The two pieces of coaxial cable connect at the ground
block to create a continuous connection between the
ERU and the SOMAport.
One #10 AWG copper grounding wire
This wire runs from the ground block to the central
building ground.
