Chapter 1: Introduction
WARNING
Do not use rigid conduits over 1 inch (25.4mm) for the EDGE Main Controller. Do not
use rigid conduits over 2 inches (50.8mm) for the EDGE 3-Slot Expansion Box and
the EDGE 6-Slot Expansion Box.
Cable Routing and Underground Trench
IMPORTANT: The same rules are applicable for the underground trench. The distance between the high
voltage and the low voltage must be at least 460 mm (18 inches) in the same cable tray or
conduit and between two different conduits in parallel.
WARNING
Follow the regulations and electrical code according to your area. Underground
trenches must be installed by a qualified contractor.
Grounding recommendations for 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.
