nVent ERICO System
3000
Installation
Pre-Installation
Prior to the installation of the
lightning protection grounding
systems, it is important to refer to site
drawings of all underground services to
ensure that these are avoided and not
interrupted during trenching, excavation,
boring or driving ground rods,
(see Figures
1
,
2
,
3
and
4
).
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).
The grounding system is critical to the
integrity of any lightning protection
installation and should include
consideration of:
• Latest Revisions of Standards compliance:
(IEC
62305
-
1
, BS EN
61068
-
1
, SAA AS/NZS
1768
, NFPA
®
780
, CSA C
22
.

, NEC
®
etc.)
and also any local standards and Codes
in accordance with authorities having
juristiction.
• Available space / location.
• Natural soil conditions including resistivity,
moisture, temperature, and chemical
content.
• Location of underground services - Power,
Communications, Fuel, Gas, Water, etc.
• Use of suitable grounding rods such as
nVent ERICO rods.
Contact nVent ERICO customer service,
or Distributor, if you require additional
assistance.
During the installation of the System
3000
, all site restrictions and safety requirements must
be followed.
The recommended order of installation is as follows:
1. Full installation of the grounding system
2. Full installation of the downconductor
3. Termination of the downconductor to the grounding system
4. Construction of the mast, insertion of the upper termination into the FRP mast and
connection to the nVent ERICO Dynasphere air terminal
5. Termination of bonding cable from upper termination to structure is required to be
grounded (refer to Downconductors section of the manual on page
13
)
6. Raise mast into position and secure
