Grounding SystemsThe grounding system is critical to
the integrity of any lightning protection
installation and should include
consideration of:
•Local Standards com pliance (IEC
61024-1, BS 6551, A S1768-1991,
N FPA 780, C 22.1-98, N EC ® etc.)
•Available space/location.
•N atural soil conditions - resistivity of
soil, soil m oisture content, soil
tem perature range, etc.
•Location of underground services -
Pow er, C om m unications, Fuel, G as,
W ater, etc.
•C orrosive environm ents, ie: salt
w ater, acid/alkaline contam inated
ground m ass.
•U se of suitable grounding rods such
as ERITEC H rods.
•M inim ization of risk to personnel.
C ontact your area ERIC O office or
D istributor if you require further advice on
grounding system s.
Downconductors
The ERIC O RE dow nconductor or other
recom m ended dow nconductor should have
been selected during the design stage, as
should the route, length and any
preterm inations of the dow nconductor.
Re-check intended route of
dow nconductor immediately
prior to insta lla t ion t o ensure
t h a t :
The recommended order of installation is as follows:
1. Full insta lla tion of the g round ing syste m.
2. Full insta lla t ion of the do w nconducto r.
3. Termina tion of the do w nconductor to the grounding system .4. Upper terminat ion of the dow nconductor (ma y alread y have been
completed by ERICO) and connection to the DYNASPHERE air terminal.
5. Termina tion of bon ding ca ble from upper terminat ion to structure
(if required).
6. Ra ise ma st into position a nd secure.
•There are no structural changes or
additions that m ay effect the initial
Benji registered* design.
•M ost direct route possible to thegrounding system w ith m inim al
num ber of bends and as flush w ith
the structure as possible.
•M inim um bending radii m aintained
(500m m , 20in.).
*Registered site design w ith ERIC O

•Parallel routing w ith other services -
m inim um separation = 2m (80in.).
•A ttachm ent to the structure is at a
m axim um of every 1m (40in.) for the
top 10% of the dow nconductor route
and 2m (80in.) from then on.
Recheck:
•Securing of dow nconductor -
saddles, cable ties, beam clam ps,
cable hangers, etc, are appropriate.
•M ethod of cable installation, ie. cable
upper term inated on the outside of
the drum - to be rolled off from the
base of the structure, or cable upper
term inated on the inside of the drum- to be rolled off from the top of the
structure. (Refer Fig. 6 on page 15).
•The outer sheath of the dow n -
conductor m ust be electrically
bonded to a conductive structural
point w ithin 5 m eters (17ft) of the
upper term ination kit.
Structural Bonding Braid & ConductiveStructural Points
W hen installing the upper end of
the dow nconductor on a m asonry
structure (concrete panels, brick,
etc), the dow nconductor should be secured
directly to the structural steel w ork. If this
cannot be done w ithin 5 m eters (17ft.) of the
upper term ination, then the bonding cable
(supplied in the term ination kit) m ust be
connected via 6m m2
(8W G ) insulated coppercable to the nearest conductive structural
point. This point should be w here the
dow nconductor first com es into contact w ith
the structure and m ay be either structural
steel w ork or the reinforcing w ithin concrete
panels or slabs.
It is recom m ended that this point be
determ ined prior to the installation to allow
for any site w ork or equipm ent that m ay be
required prior to the installation.
The 6m m 2 (8 AW G ) cable is not supplied
and the length of the cable w ill need to be
determ ined and obtained before com m encingthe installation.
See Pages 18 to 24, figures 10-17 for m ore
details and diagram s.
There is no need to connect the Structure
Bonding Braid if the dow nconductor can be
secured to a low er m etallic m ast section that
has its base electrically bonded to the steel
w ork of the structure.
Lightning Event Counters
The Lightning Event C ounter (LEC IV) is
a device for registering and recording the
num ber of strikes that the ERITEC H System
3000 has intercepted. The design of this
counter allow s m any installation alternatives
on the dow nconductor as discussed in later
text. A lso, see Specifications on page 54.
The follow ing should be considered prior to
installation of the Lightning Event C ounter:
•It is advisable to locate the LEC IV in
a secure area that is not prone to
contact w ith m oving objects, theft, or
vandalism .
•If the LEC IV is to be encased in an
additional enclosure, ensure that it is
m ounted to enable easy access to the
display. See figure 33 on page 49.

DYNASPHERE Terminals
The D YN A SPH ERE is the air term inal of the
ERITECH System 3000.
Ensure that the appropriate air term inal has
been provided.
Suitable for use in:
•G eneral purpose applications
•H igh tem perature environm ents
•C orrosive environm ents (salt or acid
atm osphere)
Ensure the air term inal is supplied w ith the
finial tip secured in place. The air term inal is
supplied w ith three different finial tip config-
urations (tw o separate, and one secured inplace), sim ilar to that show n in photo 1.
It is important that the correct finial tipis installed, specific to the application.Photo 2 show s the three different finial tip
sizes, ranging from sharp to blunt in dim ension.
The sharp tip (m iddle), m edium tip (left) and
rounded tip (right). The application of each of
these tips is detailed below :
•Sharp Tip –Term inal heights less than
20m (65 feet)
•M edium Tip –Term inal heights less than
50m (165 feet), greater than 20m (65 feet)
•Rounded Tip –Term inal heights greater
than 50m (165 feet)Note: heights listed refer to the actual term inal height above ground level
If required, replace the finial tip supplied
w ith the appropriate tip for the application,
and tighten firm ly.
Warning – Do not install the DYNASPHERE
without installing the correct finial tip.
1 – DYNASPHERE w ith two spare f inial tips
2 – Three (3) DYNASPHERE finial tip sizes
Masts
There are three m ain types of m ast
configurations:
•G uyed - generally required for m ast
heights of over 3 m eters (10ft) or for
clim atic conditions w here w ind gusts m ay
exceed 160 km /h (100m ph). A lw ays
consult w ith a local civil engineer if indoubt. The m ast is anchored at the base
and then guyed using one or tw o guy
sets, depending on the m ast height and
configuration, each w ith 3 lengths of
non conductive guying m aterial.
•C antilevered - the low er third of the
m ast is secured to a vertical surface to
provide support. These m ay also require
guying depending on m ast height.
•Free-standing - base support only.
Ensure that the configurations and heights
for your specific installation conform to the
Benji design and consultation directives.
Specific advice for each m ast configuration
is provided on pages 41 to 48.
W hen all of the com ponents for the
ERITEC H System 3000 have been received,
they should be checked against the Benjidesign “Bill of M aterials”and for any possible
shipping loss or dam age.

W hen using ground rods it is advisable to:
•U se driving heads to prevent
m ushroom ing on top of rod.
•U se driving heads w hen using
coupled rods.
•U se a post or picket driver.
W hen bonding the grounding system
com ponents, try to use the recom m ended
m ethods suggested below :
•CADW ELD ® connections m ust be used
to provide perm anent electrical bonding,
corrosion resistance and m echanical
strength betw een conductors, including
m ost types of copper cable, bar, rod,
tape, structural steel w ork, reinforcing
steel and pipe.
•Supplied ground rod clam ps should
be used for term ination of ERIC O RE
dow nconductors directly to ground
rods. This allow s later disconnection
for m aintenance requirem ents.
•U se of alum inum lugs or couplings is
prohibited.
•W aterproofing m astic tape should be
used for w aterproofing corrosionvulnerable connections.
Ground Resistance LoweringCompounds
G round enhancing com pounds (such asG EM ) are recom m ended and supplied w hen
the existing soil m ass has a high resistivity.
These com pounds can be used to increasethe total surface area of grounding conductors,
thereby reducing the ground resistance/im pedance.
C om pounds m ay require w ater and am ixing container.
W hen applying these com pounds, be sure
to take necessary handling precautions asadvised by the product instructions, and
ensure that the directions for use are
follow ed correctly.
Insulation of GroundingSystems
In som e installations, it m ay be necessaryto insulate part of the ground system from anarea of the surface, for the purposes of safety
or isolation (pedestrian w alkw ays, proxim ityto other services, etc.). In this situation, it is
recom m ended that a m inim um of 70m m
2
(2/0 AW G ), insulated copper cable is run in
PV C conduit to the connection point (start) ofthe intended ground system . This conduit
should be at a depth of at least 600m m(24in.), or greater if required, to ensure that it
is below the frost line to the start of theintended ground system .
A nother possible design m ethod for
reducing surface step-potentials m ay be toinsulate the ground system for the first few
m eters of depth from the surface. This isdone by isolating the initial injection point of
the dow nconductor from the surface of theground m ass by running it through PVCconduit to the required depth before
exposing it to the ground m ass.
Bonding the LightningProtection Ground to Other
Service GroundsW here separate grounds exist eg:
Structure, Pow er, C om m unications and

Lightning Protection, they should be bondedtogether to form an equipotential ground
plane. This w ill elim inate the possibility of
ground loops and potential differences arising
under transient conditions.
A uthorization m ay be required by the
particular service providers before bonding of
these grounds takes place.
Bonding cable m ust be 70m m 2 (2/0 AW G )
m inim um depending on local standards. In
som e circum stances, it m ay be necessary to
use a Transient Earth C lam p (ERIC O Part N o.
TEC 100C ) w hich effectively bonds all grounds
to the sam e potential under transient
conditions, to satisfy service providers.
For further inform ation, it is advised that
local applicable standards are consulted, ie
IEC 61024-1, BS 6551, A S1768, N FPA 780,
C 22.1-98 and N EC.

Downconductor Hauling
Locate the dow nconductor cable drum at
the appropriate location (refer to figure 6).
W hen hauling the dow nconductor, use thefollow ing guide points:
•Ensure that the cable drum , if supplied, is
in a serviceable condition.
• If the dow nconductor has been upper
term inated on the outside of the drum ,
then the dow nconductor m ust be hauled
off the drum from the ground.
•If the dow nconductor has been upper
term inated on the inside of the drum ,then the drum m ust be at or near the top
of the structure, so that the dow nconductor
can be unw ound from the drum tow ards
the base (refer to figure 6).
•W hen using slings or ropes to haul
dow nconductors, use M U LTIPLE hitches
around the cable.
•D O N O T sling from the term ination
coupling or cold-shrink section of theterm inated dow nconductor.
•D O N O T use cable stockings over
TERM IN ATED dow nconductor ends.
•Protect the dow nconductor from
abrasion and tearing w hen hauling over
rough surfaces, at all tim es, especially
around corners or through penetrations.
Downconductors
Depending on site requirements, the downconductor(s) may have their
upper terminations completed at a pre-specified end of the cable byERICO be fo re shipment . These te rminat ions w ill be prot ected by a sho rt

Penetrations
Before routing the dow nconductor through
any penetrations, ensure that:
•If un-term inated, a m inim um hole
diam eter of 50m m (2in.) is provided.
•If term inated, a m inim um hole diam eter of60m m (23/8in.) is provided.
•Enough physical protection (conduit
or sim ilar) is provided to stop the
dow nconductor being dam aged w hen
being fed through the penetration.
•W hen feeding the upper term ination of
the dow nconductor through any
penetrations, the term ination sheds
(flanges) should be tem porarily w rapped in
insulation tape to reduce their diam eter
and protect them against abrasion. This is
very im portant as the cold-shrink tubes
are susceptible to tearing if nicked or
scuffed.
If either side of the penetration requires
environm ental protection ie: w aterproofing,
air-con pressure seal, etc., use a suitable
sealant or deck sealing gland.
Routing
The rout e ta ken by the
do w ncond uctor is very
impor tan t and must
fo llow the se rules:
•C arefully survey the intended route of
the dow nconductor im m ediately prior to
the installation to check for any alterations
that m ay effect the original Benji design,
ie: structural changes, new antenna or
m ast installations, air conditioning tow ers
or ducting, etc.
•U se the m ost direct route practical to
m inim ize the dow nconductor length.
•To m inim ize the risk of side-flash, D O N O T
route the dow nconductor back beside
itself after change of direction, ie: 180º.

•Parallel routing w ith other services -M inim um separation = 2m (80in.).
Try to isolate as m uch as possible from
other services.
•If the dow nconductor m ust cross other
services, ensure that it crosses at right
angles to m inim ize any inductive effect.
•The low er end of the dow nconductor
m ust term inate as close as possible to
the initial injection point of the
grounding system .
• A llow 500m m (20 in.) of slack in
the length of dow n-conductor at
the upper end of the cable tofacilitate m ast erection and correct seating
of the D ynasphere term inal in the top of
the FRP m ast.

N O TE: This is the only tim e that the
dow nconductor should be isolated from the
structure and generally only for 2.4 m eters
(8 feet) m axim um .DO NOT route the entirelength of downconductor in insulatedconduit.
•To seat the term inal correctly in the top ofthe FRP m ast, any cable slack w ill have to
be rem oved from the m ast w hile also
m inim izing any stress on the upper
term ination sheds (flanges) by tw isting the
FRP m ast against the term inal for at least

If the dow nconductor is dam aged
during installation, it m ust be
checked by an ERIC O representative
to see if the dam age w ill effect its safe
operation.
Securing the Downconductor
Securing of the dow nconductor
not only provides a m echanical
attachm ent to the structure, but
also an Electrostatic connection to the
structure via the sem i-conductive outer
sheath of the dow nconductor cable.It is im portant that the dow nconductor
is both physically and electrically secured
to the entire length of the structure to
relieve both physical and electrical stresses
along the dow nconductors’length.
The electrical bonding of the dow n-
conductor is especially im portant for at
least the first 10% of the dow nconductor
route from the upper term ination, and for
this reason the dow nconductor m ust besecured at least every 1 m eter (40in.).
ERITEC H saddles and conductive
clam ps are recom m ended for the
purpose of securing the
dow nconductor. These have been specifically
designed and m anufactured to m echanically
secure and electrically bond the ERIC O REto
the structure, w hile m inim izing stress points
on the cable.
U se of non ERITEC H saddles can com prom ise

w hich can lead to flashover (see Figure 10).
Use ERITECH clamps only

Structure Bonding Braid
In som e situations, it m ay be difficult to get
a good electrical bond betw een the dow n-
conductor and the structure as the structure
m ay be either concrete, m asonry or other
m aterial w hich is a poor electrical conductor.To ensure that the upper end of the dow n-
conductor can be adequately electrically
bonded to the structure, a Structure Bonding
Braid has been provided at the base of the
upper term ination of the dow nconductor.
This Braid is a 75m m (3in.) tail w hich exits
from under the term ination coldshrink and is
supplied w ith a connector to allow connection
to a 6m m 2 (8 AW G ) copper cable (as
m entioned in the follow ing text). In difficult
electrical bonding situations, this can beconnected to a conductive structural point
to relieve the electrical stresses on the
dow nconductor and m asonry surfaces.
To determ ine w hether the use of the
structure bonding braid is required in specific
installations, please study the follow ing
carefully, and refer to the flow chart on page
21 (opposite). For an explanation of term s,

The Insulat ion Cut t ing Too l uses
fr ict ion to cut into th e sheath and is
less likely t o d amage t he layers
under neath t han using a kni f e. When
th e instru ct ion s cal l for t he kni f e to be
used, be sure n ot to cut any deeper
th an instru cted.
If the instructions are not follow ed
correctly, or if any of the insulation layers or
the copper foil are incorrectly cut, then the
integrity of the lightning protection is
affected.

1. A t a distance of 600m m (235/8 in.) from
the end of the cable, carefully cut a shallownotch into the black outer insulation no
deeper than 1m m , (3/64 in.). Then, using the
insulation cutting tool, cut around the
circum ference of the black outer insulation
until the copper screen underneath is
exposed.
2. U sing a knife, carefully cut the outerinsulation of the cable to a depth of no m ore
than 1m m (3/64 in.), for the full 600m m (235/8

Guying
ERIC O has standard 4m (13 1/2ft.) and 7m
(241/2ft.) G uying Kits. If the guying of a
fiberglass m ast is required, then the appropriate
guying kit should be selected to suit the
application. The guying m aterial is m ade up
of light w eight plastic coated fiberglass,
w hich is non-conductive.
If a custom ized guy kit has been supplied,
then the actual guy length can be determ ined
from the follow ing:
G uy Length = 1.41 X
W here X = the vertical height betw een the
upper and low er guying points and the
assum ed angle from horizontal is 45 .̊
Import ant recommendat ions:
• W hen guying any m ast, it is advisable
that the guying angle be no greater than
60° from horizontal.
• It is recom m ended that 8m m (5/16in.)diam eter stainless steel guying saddles are
used for the base guy anchor points. Ifthese are to be anchored to a concrete
surface, then 6m m (1/4in.) diam eter x40m m (15/8in.) depth (m inim um ) m asonry
anchors or sim ilar should be used.
• Each of the guying kits com es w ith sixstainless steel thim bles to relieve stress on
the guys at the anchor points. Thesethim bles M U ST be used w hen guying.
See Figure 30.
• W hen using shackles (5m m (3/16in.)
m inim um ), ensure that the shacklepins are secured w ith nichrom e w ire.
W hen securing the fiberglass guys, use theguying grips supplied in the guying kit,
carefully follow ing the instructions provided.U se of alternative w ire rope grips is
acceptable but ensure that:
• G rips are m ade of a suitable m aterial
to PREVEN T corrosion.
• M inim um of 3 grips per guy end.
• G rips spaced at a m inim um of 30m m(11/4in.) on guys (or 6 x guy diam eter).
• G rips are correctly orientated - gripbase (saddle) on the ‘Live’side of the
guy and ‘U -bolt’over the ‘D ead’sideor tail of the guy.
• N o m ore than 60cN.m (5 lbf.in) of
torque is applied to the grip.
The above recom m endations should alsobe used for any other guying, ie: stainless
steel, w hen used on any m ast.

Raising of MastW hen ready to raise the m ast, check the
follow ing:
•G uys to the inline coupling, guying ring
or other m ast anchor points are properly
secured.
•Ensure the guys are not tw isted, kinked or
dam aged in any w ay.
•Ensure that each guy can be easily securedat the base w hen the m ast has been
raised.
Turnbuckles or rigging screw s are
recom m ended at the base anchor points of
the guys to enable easy vertical alignm ent of
the m ast and correct tensioning of the guys.
If using turn-buckles, ensure that they are
w ired securely w ith nichrom e w ire.
U sing conductive guying, such as stainlesssteel, is acceptable as long as it is NO T used
for guying to the top of sections of insulated
FRP m ast. G uying to the top of an alum inum
section of m ast is acceptable.
Rememb er t o alw ays Plan t he Lift before at t empt ing i t .
If the m ast is to be raised by hand, ensure
that it can be safely and easily m anaged
m anually.
It is recom m ended that the use of a crane
or other suitable equipm ent be used for
anything over 6 m eters (20ft.) in height, or
for hazardous area installations such as high
elevations (tow ers).
To m inim ize the possibility of the m ast
becom ing bent or dam aged, it is very
im portant to keep the m ast straight during
the lift.
Ensure that:
• There are no overhead A C pow er
lines.
•There is nothing overhead that w illobstruct the lift.
•There is enough m an-pow er
