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




6 www.erico.com

•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 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




13www.erico.com

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

lengt h o f flexible PVC tube.

It is VERY IMPORTANT th at w hen rem ov ing t hese t ubes, they are not

removed w ith a kni f e or cut in any w ay as th is w i l l damage the out er layer

of th e terminat ion. It is sugg ested t hat t he tape and cover are best removed

by hand . (See fig ure 6)

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,

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

the outer sheath, creating high stress points

w hich can lead to flashover (see Figure 10).

Use ERITECH clamps only

Figu re 10 : Detail shows the need to use ERITECH

Clamps.

•For brick and concrete w alls or roofs,

use the ERITEC H stainless steel saddles

provided. These have tw o 6m m (1/4 in.)

diam eter holes on either side and are

suitable for use w ith m asonry anchors.

These saddles can also be used w ith other

suitable fastenings against w ood, fiberglassand m etallic surfaces.

•W hen securing externally to round section

structures such as pipes, tow er legs,

m asts, etc, stainless steel cable ties are

recom m ended. Ensure that these are

firm ly secured.

•For securing to other structures such as

angle iron, ie: radio tow ers, structural

beam s etc., use ERIC O C A D D Y beam

clam ps and suitable cable clam ps.

•If the dow nconductor is to be routed

above a false ceiling, ensure that it is

fixed to the underside of the concrete

floor slab.

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,

Three basic types of m ast configuration

include:

Guyed

•Single length guyed - one section of

FRP (Fiberglass Reinforced Plastic)

m ast m aterial guyed at the top.

•D ouble length guyed - tw o sections of

m ast m aterial, usually alum inum low er and

FRP upper, guyed betw een the tw o sections

and at the top.

Cantilevered

U sed in situations w here it is m ore practicalto m ount w ithout a base, eg: radio tow ers.

•A t least one third of the low er m ast

should be secured against the structure.

•C antilevered m asts can either be free

standing or guyed for extra stability.

FreestandingO ften used w here the term inal,

dow nconductor and grounding system are

isolated from volatile areas by installing theERITEC H System 3000 at least 5m (17ft.) aw ayfrom those areas.




42 www.erico.com

Before the installation of the m ast, ensure

that:

•The free standing m ast is supplied w ith an

appropriate spigot, suitable for either

internal or external m ounting of the FRP

m ast.

•D ow nconductor is to be routed

internally or externally.

•Provision for external or internal m ounting

of LECIV and access.

•D ow nconductor is able to exit through the

base of the free standing m ast.

The free standing m ast requirem ents for

foundations and erection are generallyhandled by the m ast m anufacturers.

Mast Bases

ERIC O supplies a range of alum inum bases

to suit:

•ERITECH FRP m asts (alum inum base w ith

an internal m ast spigot).

•A lum inum m asts (w elded directly onto

the required length of m ast.)

Both base types have dow nconductor

exit holes in the base, required if the

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
