Due to ongoing research into the phenomena of lightning and lightning protection
technology and product improvement, nVent ERICO reserves the right to alter any
information and specifications contained herein at any time without notice. Users
should check with nVent ERICO to ensure they have the latest edition.
Lightning protection standards outline design or calculating methods, to place air
terminals on structures. i.e. they calculate the attractive or protection radius of a
particular air terminal in accordance with each particular design method, so that
the air terminals can be manually positioned on structures to provide the best
coverage. The common design methods for each of these standards are based on
the Electro-Geometric Model.
The design method employed to position the System  air terminals on the
structure, the Collection Volume Method (CVM), is based on an improved Electro-
Geometric Model. Similar to the rolling sphere or striking distance formulae used
generally in lightning protection standards, the CVM employs additional lightning
parameters in its striking distance formulae, namely electric field intensification
factor, and structure height and physical shape. The formula in the CVM also takes
into account such parameters as the velocity ratio of the lightning down-leader to
up-leader streamers, humidity and the height above sea level.
As a system, the combination of the products and the placement method used in
the design and installation of the nVent ERICO System  does not comply with
any particular standard. However, the actual components of the System  are in
full compliance with certain standards (in terms of lightning current handling ability,
material of construction, etc). The Dynasphere air terminal is UL listed and complies
with standard UL, emphasizing the compliance to accept lightning current exposure.
Since system  does not comply with any particular standard, it is important
to follow the instructions published in the nVent ERICO System  Installation,
Operation and Maintenance Manual. nVent ERICO offers inspection services for
system  installations and can issue a Certificate of Installation Compliance for
qualifying installations.

Pre-Installation Requirements
This manual is a guide to the installation,
operation and maintenance of the
nVent ERICO System  Lightning
Protection System.
It assumes that the system to be installed
has been designed by an authorized nVent
ERICO representative. The system design
will include:
• Grounding system designed as a result of
soil resistivity analysis.
• Downconductor routes chosen
to avoid other services, maintain
minimum bending radii and minimize
downconductor run length.
• Downconductor securing requirements..
• Terminal types – operating environment.
• CAD software design report which
determines terminal placement, mast &
height requirements as well as protection
level calculations.
All of the above are recommendations for
a successful installation. If there is any
doubt about any of the points mentioned,
please contact nVent ERICO or your nearest
distributor for clarification.
CHECKING LIGHTNING
PROTECTION COMPONENTS
PRIOR TO INSTALLATION
Before installation, perform following
inspection:
Terminal(s)
• nVent ERICO Dynasphere terminals have
not been dented.
• The correct finial tip has been installed,
based on the overall height of the air
terminal above grade.
nVent ERICO Ericore downconductor(s)
• The cable drum (if supplied) is in a
serviceable condition.
• Correct length(s).
• That there is no obvious damage to
the cable.
• Make sure that the end of cable is
properly sealed to prevent moisture
migragting into cable strands.
• Is teminated as required. If the
downconductor has been preterminated
before shipment, check that the
termination is still intact and in good
order. See note on Page  on removing
protective covers.
• If the Upper Termination Kit has been
supplied separately, check that the cold-
shrink tube in the kit is in good order, has
no tears or cuts and has not collapsed.
• Applications engineering does not
recommend field installations of upper
terminations unless the operators are
trained by nVent Applications Engineering.
This information along with downconductor
lengths and quantities (if more than one
length on the one drum), will be printed on
a label on the side of the cable drum(s).

nVent ERICO System  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 , , and ).
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 <
The grounding system is critical to the
integrity of any lightning protection
installation and should include
consideration of:
• Latest Revisions of Standards compliance:
(IEC -, BS EN -, SAA AS/NZS
, NFPA®, CSA C., 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 , 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 )
6. Raise mast into position and secure

When driving ground rods it is advisable
to use nVent ERICO ground rod drivers or
drive sleeves to prevent mushrooming on
the top of the rod. When coupling rods, use
compression type ground rod couplers.
When bonding the grounding system
components, use the recommended
methods suggested below:
• nVent ERICO Cadweld connections
should be used for all below grade
connections. Cadweld connections
provide permanent electrical bonding,
corrosion resistance and mechanical
strength between conductors, including
most types of copper cable, bar, rod,
tape, structural steel work, reinforcing
steel and pipe.
• Supplied ground rod clamps should
be used for termination of Ericore
downconductors directly to ground rods.
This allows later disconnection
for maintenance requirements.
• Use of aluminum lugs or couplings
is prohibited.
• Supplied waterproofing mastic tape
should be used for waterproofing
corrosion vulnerable connections and
must be used be used in all Ericore to
ground rod connections.
Ground Resistance
Lowering Compounds
Ground enhancement material, nVent
ERICO PN GEMA, is recommended and
supplied when the existing soil mass has
a high resistivity.
GEMA can be used to increase the
total surface area of grounding
conductors, thereby reducing the ground
resistance / impedance.
GEMA requires water and a mixing
container. Follow the installation instructions
printed on the bag or bucket provided.
Insulation of Grounding Systems
In some installations, it may be necessary
to insulate part of the ground system from
an area of the surface, for the purposes of
safety or isolation (pedestrian walkways,
proximity to other services, etc.). In
this situation, it is recommended that a
minimum of  mm(/AWG), insulated
copper cable is run in PVC conduit to the
connection point (start) of the intended
ground system. This conduit should be at a
depth of at least  mm ( in.), or greater
if required, to ensure that it is below the
frost line to the start of the intended ground
system (see Figure ).
Bonding the Lightning Protection
Ground to Other Service Grounds
Where separate grounds exist and
the structures have mutual electical
connections e.g.: Structure, Power, Signal,
Communications and Lightning Protection,
they should be bonded together to form
an equipotential ground plane. This will
eliminate the possibility of ground loops
and potential differences that arise under
transient conditions.

12 | nVent.com/ERICO
Authorization may be required by the
particular service providers before bonding
of these grounds takes place. The size of the
bonding cable depends on local standards,
but should be at least  mm(/AWG)
or larger.
In some circumstances, it may be necessary
to use a Potential Equalization Clamp
(PEC) which effectively bonds all grounds
to the same potential under transient
conditions, to satisfy service providers.
Conductor to Grounding
System Connection
When determining the length of nVent
ERICO Ericore conductor required in a
particular situation it is prudent to make the
Figure : Various methods of isolating the ground system
connection to the grounding system at the
first available opportunity. The practice of
running nVent ERICO Ericore downconductor
for long horizontal lengths at the ground
level to reach a designated earth point is
discouraged. Instead, a lower termination
should be made to a ground rod upon
reaching the ground level. Then a separate
length of conventional grounding conductor
should be connected from the ground rod to
other earthing points as required.
Labelling
The labelling of Inspection Wells or grounding
systems to local requirements is the
responsibility of the customer / installer.

Downconductor Hauling
Locate the downconductor cable drum at
the appropriate location (refer to Figure ).
When hauling the downconductor, use the
following guide points:
• Ensure that the cable drum, if supplied, is
in a serviceable condition.
• If the downconductor has been upper
terminated on the outside of the drum,
then the downconductor must be hauled
off the drum from the ground.
• If the downconductor has been upper
terminated on the inside of the drum, then
the drum must be at or near the top of the
structure, so that the downconductor can
be unwound from the drum towards the
grade (see Figure ).
ERICORE DOWNCONDUCTOR
All nVent ERICO Ericore purpose-designed downconductors have a semi-conductive
outer sheath which is approximately mm (. in.) thick. Rough or careless handling
of the downconductor can damage this sheath and compromise its performance.
It is VERY IMPORTANT that when removing these tubes, they are not removed with a
knife or cut in any way as this will damage the outer layer of the termination. e.g. It is
suggested that the tape and cover are best removed by hand. (See Figure 6)
Depending on site requirements, the downconductor(s) may have their upper
terminations completed at a pre-specified end of the cable by nVent ERICO before
shipment. These terminations will be protected by a short length of flexible PVC tube.
The nVent ERICO Ericore downconductor or other recommended downconductor,
route, length and any pre-terminations should have been selected during the
design stage.
• When using slings or ropes to haul
downconductors, use MULTIPLE hitches
around the cable.
• DO NOT sling from the termination
coupling or cold-shrink section of the
terminated downconductor.
• DO NOT use cable stockings over
terminated downconductor ends.
• Protect the downconductor from abrasion
and tearing when hauling over rough
surfaces, at all times, especially around
corners or through penetrations.

Penetrations
Before routing the downconductor through
any penetrations, ensure that:
• If un-terminated, the hole is a minimum of
 mm (in.) in diameter.
• If terminated, the hole is a minimum of
 mm (
• The hole must be smooth and without
sharp edges.
• A max of m (ft) of non-conductive
conduit can be used, to protect the Ericore
cable from damage, when routed through
concrete or masonry opening.
• A max of m (ft) of non-conductive
conduit can be used over any part of the
top % of the cable length.
• Ferro-magnetic counduit is never used.
If either side of the penetration requires
environmental protection i.e.: waterproofing,
air-con pressure seal etc., use a standard
professional method of protection.
Figure : Correct & incorrect cable routing methods
Routing
The route taken by the
downconductor is very important
and must follow these rules:
• Carefully survey the intended route of the
downconductor immediately prior to the
installation to check for any alterations
that may effect the original design, i.e.:
structural changes, new antenna or mast
installations, air conditioning towers or
ducting, etc.
• Use the most direct route practical to
minimize the downconductor length.
• To minimize the risk of side-flash,
DO NOT route the downconductor back
beside itself after change of direction,
i.e.: °.
• Minimize the number of bends.
• Minimize the strain on the downconductor
during installation.
• The Ericore cable must be installed in a
downward fashion.

reasons) install the cable in a suitable
insulating conduit with a minimum wall

NOTE: This is the only time that the
downconductor should be isolated from

Conduit made from ferro-magnetic
material must not be used.
• Ensure that a minimum bend radius of
> mm ( in.) is maintained.
• Parallel routing with other services -
Minimum separation = m ( in.).
Try to isolate as much as possible from
other services.
• If the downconductor must cross other
services, ensure that it crosses at right
angles to minimize any inductive effect.
• The lower end of the Ericore cable must
terminate to a grounding system.
• Allow  mm ( in.) of slack in the

nVent ERICO brand of saddles and
conductive clamps are
recommended for the purpose of securing
the downconductor. These have been
specifically designed and manufactured to
mechanically secure and electrically bond
the nVent ERICO Ericore to the structure,
while minimizing stress points on the cable.
Only use nVent ERICO provided
clamps. Use of an alternative brand
of saddle can compromise the outer sheath,
creating high stress points which can lead to
flashover (see Figure ).
• To seat the terminal correctly in the top
of the FRP mast, any cable slack will
have to be removed from the mast while
also minimizing any stress on the upper
termination sheds (flanges) by twisting
the FRP mast against the terminal for at
least one turn.
If the downconductor is damaged
during installation, it is no longer
usable and must be replaced.
Securing the Downconductor
Securing of the downconductor
not only provides a mechanical
attachment to the structure, but also an
electro-static connection to the structure
via the semiconductive outer sheath of
the downconductor cable.
It is important that the downconductor is
both physically and electrically secured to
the entire length of the structure to relieve
both physical and electrical stresses
along the downconductors’ length.
The electrical bonding of the
downconductor is especially important
for at least the first % of the
downconductor route from the upper
termination, and for this reason the
downconductor must be secured at least
every m ( in.). Roof penetrations are
acceptable within the first % of the
downconductor route. Figure : Detail shows the need to use
nVent ERICO clamps
Use nVent ERICO clamps only

18 | nVent.com/ERICO
• For brick and concrete walls or roofs, use
the nVent ERICO brand of stainless steel
saddles. These have two mm
(¼ in.) diameter holes on either side
and are suitable for use with masonry
anchors. These saddles can also be used
with other suitable fastenings against
wood, fiberglass and metallic surfaces.
• When securing externally to round section
structures such as pipes, tower legs,
masts etc. stainless steel cable ties are
recommended. Ensure that these are
firmly secured.
• For securing to other structures such as
angle iron i.e.: radio towers, structural
beams etc., use nVent CADDY brand of
beam clamps and suitable cable clamps
from nVent ERICO.
• If the downconductor is to be routed
above a false ceiling, ensure that it is fixed
to the underside of the concrete floor slab
using stainless steel saddles.
• Use of exothermic fastening methods
on nVent ERICO brand of saddles is
NOT recommended.
• Use of nVent CADDY ERISTRUT (or other
similar strut system) is recommended
where suitable (see Figure ).

VITAL WARNING LABELS must be
located at eye level and on at least one of
these locations:
• Where there is the possibility of personnel
being in close proximity to the cable
• Where the downconductor terminates to
the grounding system
• At the mast base
There is a VITAL WARNING LABEL supplied in
each of the upper and lower termination kits.
If more labels are required, contact your
nearest nVent ERICO Distributor.
Structure Bonding Braid
To ensure that the upper end of the
downconductor can be adequately
electrically bonded to the structure, a
Structure Bonding Braid has been provided
at the base of the upper termination of
the downconductor. This braid is a 
mm (in.) tail which exits from under the
termination heatshrink and is supplied with
a connector to allow connection to a mm
(AWG) copper cable (as mentioned in the
following text). This must be connected to
a conductive structural point to relieve the
electrical stresses on the downconductor
and masonry surfaces.
The use of the Structure Bonding
Braid is NOT optional, and MUST
always be used.

After routing the downconductor, it
must be kept in constant physical
contact with the structure via conductive
fixings as follows:
For the top % of the downconductor:
• The downconductor from the terminal
must be secured at least every
m ( in.). This includes metallic
mast sections.
• Installing the downconductor through
ferromagnetic raceways, pipes, and
conduits is not recommended.
For the lower % of the downconductor:
• The downconductor must be secured
at least every m ( in.). This includes
routing inside any type of pipe or conduit.
• The length of the downconductor through
non-ferromagnetic raceways, pipes, and
conduits should not exceed m ( in).
• Installing the downconductor through
ferromagnetic raceways, pipes, and
conduits is not recommended.
When using metallic lower sections
of mast (i.e.: aluminum), then the
downconductor MUST be secured with
nVent ERICO brand of saddles to the mast at
m ( in.) intervals (max.). The mast in turn
must be electrically bonded to the nearest
conductive structural point. In this case, the
structure bonding braid must connect to the
inline coupling (see Fig. ).
Figure : Connection of structure bonding braid in
FRP and metallic masts
The mm(AWG) copper cable used to
connect the structure bonding braid to the
structure must be one continuous length.
Joints in this cable would represent a
potential maintenance issue.
Any metallic surfaces that the
downconductor may be secured to, if
possible, should be electrically connected to
the structural steel work.
