System grounding
Proper grounding is essential to system operation. The SL-1 system requires
a single-point ground. Proper grounding is required for trouble-free operation
and for the safety of personnel. The DC resistance of the conductor joining
the SL-1 system system ground reference to the main building ground should
be as close to zero as possible. The maximum total resistance from an SL-1
System pedestal to the main building ground cannot exceed 0.5 ohms, The
external earth ground should meet
and for the safety of personnel. The DC resistance of the conductor joining
the SL-1 system system ground reference to the main building ground should
be as close to zero as possible. The maximum total resistance from an SL-1
System pedestal to the main building ground cannot exceed 0.5 ohms, The

requirements.
Lack of proper grounding can result in an installation that is not protected
from lightning or power related faults and does not provide an optimum path
for residual AC or DC currents. This may cause:
from lightning or power related faults and does not provide an optimum path
for residual AC or DC currents. This may cause:
Hazards for personnel working on or using the equipment
Various service interruptions
Excess noise on analog circuits
High bit error rate on digital circuits
All voice and data lines leaving or entering the SL- 1 system
which mn external to the building must have fault protectors that connect
directly to earth ground. This is not the ground being discussed here.
