2.6 Grounding Considerations
To minimize the chance of damage to the unit and its connected equipment, a safety ground (NEC Class 2
compliant) is recommended, which bonds the chassis, antenna system(s), power supply and connected
data equipment to a
single-point ground, keeping all ground leads as short as possible.
Normally, the unit is adequately grounded if mounted with the flat brackets to a well-grounded metal
surface. If the unit is not mounted to a grounded surface, it is recommended that a safety ground wire be
