Grounding the Units
Grounding the Units
Ensure that the system is grounded properly. The units contain a number of static sensitive components that can 
be damaged by static discharge.
IMPORTANT: An Earth Ground Rod is Strongly 
Recommended 
and should be no further than 12 
feet from the unit and use a minimum of 12 
gauge wire in most cases. The type and length of 
earth ground rods vary by region. Contact the 
building inspector’s office in the municipality 
where you plan to install the unit for correct 
grounding materials and installation 
procedures.

NOTE: Keep ground wire as 
straight as possible.
Before digging, contact your local 
utility companies, to avoid 
damaging gas, power, or other 
underground utility lines.
DO NOT ground the units to a 
pedestal post (gooseneck) if 
one is used.
