Grounding
The earth ground connection must be stable and noise free. An improper or unstable earth ground
can induce noise in the FlexPS sensor. Do not use the fence structure as an earth ground
connection. Consult the local electrical code for grounding requirements. Avoid sharp bends in the
ground wire.
1.
Refer to the local electrical code, to install a low resistance ground rod at the processor
location.
2.
Using an approved ground wire, connect the ground rod to the ground stud on the FlexPS
mounting plate.

WARNING!
