Grounding Protection
The A8n series must be properly connected to earth ground. Failure to do so may result in
equipment damage, injury or death. Product warranty does not cover damage resulting in part or
in whole from improper grounding. An external grounding wire must be installed, especially
when A8-Ein is deployed on a non-metal pole or the metal pole is not properly grounded. Please
consult your location’s building and electrical codes and follow them, or consult standards such
as National Electric Code. The grounding screw is located at the bottom of A8n series as showed
in figure 30. Use 10 AWG wire with corrosion-resistant connectors for connecting to one or
more approved grounding rods or building’s earthing network. Earth-to-ground resistance
should not be more than 10ohms.
1.
Loose the grounding screw of A8n series.
2.
Attach a length 10 AWG bare copper with a terminal connector to the grounding screw.
3.
Tighten the screw nut.
4.
Connect the other end of grounding wire to grounding rods or earth ground.
