— Chapter 4. Mounting the RF-7000E
RF-7000E Operations Manual

Earth, Ground, and Lightning Protection
When grounding the RF-7000E and associated equipment, follow the general guidelines in the
Peninsula Engineering Solutions application note,
Installation Standards for Grounding
Requirements
.
Installing the input power to the repeater includes installing the standard electrical service grounds.
However, you must also make sure that the repeater enclosure is properly grounded to an earth
ground.
The repeater enclosure includes an external grounding lug on the bottom surface as shown in the
following figure.
Figure 27 Location of Ground Lug on Repeater Enclosure
1.
Connect the screw-compression ground lug to a suitable earth ground
—copper ground rod,
copper pipe, ground ring, grounded steel building frame or similar ground point
—using 2 to
4 mm, No. 12 to 6 AWG copper wire.
2.
Carefully dress the wire along cabinet, and the mounting surface, to the Repeater Grounding
System or the Ground Rod. Recommend using CADWELD
®
to attach the ground wire to the
rod or ground point.
NOTE:
When dressing the grounding wire, and forming it around corners; avoid making sharp bends
in the wire. Use a generous radius for each wire bend. Sharp bends will cause arc points for
lightning surges and strikes.
