ADB Safegate FLA, User Manual

Note

Depending on the design of the counterpoise lightning system, connecting the FLA directly to a dedicated ground

rod may provide more effective protection of the circuit.

6. After the FLA has been installed, reinstall the light fixture back onto the light base and torque the mounting bolts to the

required torque specifications found in the equipment product manual.
