2.4 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
attached to the screw provided on the bottom corner of the enclosure, in the recessed flat area.
Alternatively, a safety ground wire may be attached to one of the mounting bracket screws.
The use of a lightning protector is recommended where the antenna cable enters the building; Bond the
protector to the tower ground, if possible. All grounds and cabling must comply with applicable codes
and regulations. One source for lightning protection products may be found online at

2.5 Mounting Options
The unit may be mounted with flat mounting brackets
or
an optional 35 mm DIN rail attachment.
