Providing a Proper Ground

RTMS Echo User Guide
Providing a low resistance earth ground connection is essential to achieving
effective surge protection. Total resistance from the protected circuit to the
earth should be <5 ohms.
A grounding rod (see
placed as close as possible to the base of the RTMS Echo mounting pole. The
grounding conductor should be flexible copper braid or copper wire 12AWG or
larger.
Figure 2-7: Earth Ground Connection
The earth grounding rod, together with proper ground of the breakout box, and
surge protecting devices installed in close proximity of the mounting pole,
create a barrier or 'sink hole' for any charges and surges coming towards the
sensor from the surrounding area (see
