Chapter 2: Getting Started
Grounding the System
A correctly grounded system protects your equipment from electrical surges and spikes.
CAUTION
Each module must have its own ground connection from a common junction box. Do
not run the earth ground cable between the modules.
NOTICE
The ground resistance levels must comply with local and national electrical codes.
IMPORTANT: If outdoor connections are used, mount the enclosure as close as possible to the entry point
of the outdoor wiring.
IMPORTANT: An improper ground connection voids the system’s warranty.
Insert the rod into the ground until a few inches of the tip is left above ground level. Attach the cable to the
rod tip with an appropriate connector. Attach the other end of the cable to a breaker box or a junction box
near the main enclosure.

MET ALLIC ROD BEDROCK
• If the bedrock is more than 3 meters (10 feet) below ground level, drive the grounding rod vertically
3 meters (10 feet) into the ground.
• If the bedrock is more than 1.2 meters (47 inches) below ground level, drive the rod into the ground to
bedrock level and bury the remainder horizontally at least 0.6 meters (2 feet) below ground level.
• If the bedrock is less than 1.2 meters (47 inches) deep, bury the rod horizontally at least 0.6 meters
(2 feet) below ground level.
NOTE: Refer to your local regulations and practices if an adequate grounding installation isn’t possible.
Rod Specifications for Grounding
The rod specifications are guidelines only. Refer to your national and local regulations for compliance
criteria.
