Only attempt to install the
ERITECH SYSTEM 3000 during
storm-free periods.
If the terminal must be raised before
being connected to the ground system, or
cannot be immediately connected, then
attempt to connect the lower end of the
down-conductor to either the structure
steel reinforcing or some other reasonable
ground point.

systems, it is important to refer
to site drawings of all underground
ERITECH ® SYSTEM 3000 Installation
During the installation of the ERITECH ® SYSTEM 3000, all site restrictions
and safety requirements must be followed.
It is important to follow the recommended order of installation:
1. Full installation of the grounding system.
2. Full installation of the downconductor.
3. Termination of the downconductor to the grounding system.
4. Upper termination of the downconductor (may already have been completed

services to ensure that these are
avoided and not interrupted during
trenching, excavation, boring or
driving ground rods, (see figure 4 on
page 11).
Care must be taken to follow the
ground survey design. Ensure the
correct materials have been provided
and are used to achieve an acceptable
Ground DC resistance (typically <10Ω).
Examples of typical grounding systems
that may be used (Note: these may or may
not be relevant to the specific ERITECH
SYSTEM 3000 design) are shown in figures
2 and 3 on page 10.
