GUARDIAN SYSTEM 5 INSTALLATION MANUAL
As a result of continuing research and product development in the area of lightning and
lightning protection, LPI reserves the right to alter any detail contained within at any
time without notice.
Prior to installation of the Guardian System 5, installers should check with LPI or an
authorised distributor to conrm they have the most recent version of the Guardian
System 5 Installation manual.
It should be noted that 100% (100 percent) protection level for direct lightning strikes
is not possible and cannot be provided due to the lightning discharge process being a
natural atmospheric event.

Warranty
LPI’s Guardian System 5 Lightning Protection System is guaranteed against defects in materials
and workmanship for a period of 5 years from the original sales date when it was purchased
from LPI or one of its authorised distributors.
The warranty is limited to the ex factory cost of replacement of equipment providing it has been
installed and or certied by LPI or its distributor. All other costs such as freight, re-installation,
loss of prot, insurance premiums are not included.
Responsibility for other direct or indirect damages or death is also specically excluded from
the warranty.
The range of Guardian CAT terminals (or to our knowledge any other lightning protection
system) cannot provide 100% protection and therefore it is not inferred.
As conrmation of the above paragraph we refer to Australian Standard AS 1768 (2007).
Lightning Protection
Comments on the Australian Standard AS 1768 (2007).
We refer to the standard where it states that it provides authoritative guidance of a general
nature only and it is not intended to become a mandatory set of regulations.
In general, it is not economically possible to provide total protection against all the possible
damaging effects for lightning, but the recommendations in this standard will reduce the
probability of damage to a calculated acceptable level and will minimise any lightning damage
that does occur.
Thunderstorms are natural phenomena and there are no proven devices and methods capable
of preventing lightning ashes. Direct and nearby cloud-to-ground lightning discharges
can be hazardous to persons, structures, installations and many other things in or on them.
Consideration should always be given to the application of lightning protection measures.
Users are warned that direct strike lightning protection is only one aspect of the overall
protection strategy required for comprehensive structural, personnel and equipment safety.
Correctly designed and installed low impedance earthing, elimination of earth loops, systems
engineering, surge protection on power lines and transient protection of communications, data
and telephone lines are also essential.

Checking Lightning Protection Components
Supplied
The Guardian System 5 components received should be checked against the “Bill of materials”
for loss during shipping and for damage.
Check the following:
Terminal (s)
•
Terminals have not been dented or damaged in any way during transit.
• Instructions, Warning Labels, Warranty, Test Certicate and relevant mast base components
supplied.
Downconductor(s)
• The HVSC cable drum (if supplied) is not damaged.
• The correct HVSC length(s) have been supplied.
• No obvious damage to the HVSC cable.
• If a factory completed upper termination is supplied, check to see that the termination is
not damaged and conrm inside or outside termination(s).
• Order of lengths and quantities of HVSC (if multiple lengths on one drum), will be shown
on the side of the Cable Drum(s).
All site and safety requirements must be followed during the installation of the LPI Guardian
System 5.
The correct order of installation is as follows:
1. Installation of the lightning earth.
2. Installation of the HVSC downconductor.
3. Lower termination of the HVSC downconductor and connection to the lightning earth.
4. Upper termination the HVSC downconductor and connection to the Guardian CAT terminal.
5. Preparation and raising of the mast into position.

LPIGuardianSystem5shouldonlybeinstalledduringstorm-freeperiods.
If the Guardian CAT terminal needs to be raised prior to connection to the lightning earth or
immediate connection is not possible then connect the lower end of the downconductor to
structural steel reinforcing or other suitable earth point.
Installation of the Lightning Earth
Before installation of the lightning protection earth, consult site drawings of underground
services so that these are not damaged during installation of the earthing system.
Figure 9.
Guardian Install Manual V12.indd 15 22/9/08 4:25:23 PM

14 Document 36 II Guardian Version 1.02 © Copyright 2008 LPI
Earth DC resistance (typically ‹10 ohms) and impedance (typically ‹30 ohms) is required for
successful operation of LPI Guardian System 5.
LPI recommends the installation of a radial lightning earth as shown in gure 9.
• Recommended to install a 3 x 10 metre length radial trench.
• Each radial should consist of a trench (Approx: 500mm Deep x 200mm wide x 10m length).
• An earth rod should be driven at the end of each trench.
• All rods should be interconnected through the use of 25mm x 3mm copper tape. The use of
earth rod clamps to x the tape to rods is recommended.
• Use waterproong mastic on all mechanical connections.
• The application of earth enhancing compounds such as LPI RESLO and GRIP assists to
reduce soil resistivity to the recommended level of less than 10 ohms.
• An earth pit should be installed where the end of the downconductor terminates to the
lightning earth as shown in gure 9. This gives an access point for disconnection
and future testing.
• Do not lower terminate (connect) the downconductor to the earthing system at this point in
time.
Note: If due to space constraints it is not possible to install a radial earth as recommended,
consult with LPI or an authorised distributor for further advice.
When using earth rods:
• Use driving heads to prevent mushrooming on top of rod.
• Use driving heads when using coupled rods.
• Use a post or picket driver.
Recommendations for bonding the earthing system components are listed below:
• The use of the EXOWELD exothermic welding process is a safe and efcient way of
providing a permanent connection between conductors. EXOWELD connections will not
corrode or rust with age.
• DO NOT use aluminium lugs or couplings.
Guardian Install Manual V12.indd 16 22/9/08 4:25:23 PM

Document 36 II Guardian Version 1.02 © Copyright 2008 LPI15
Ground Resistance Lowering Compounds
• Ground resistance lowering compounds (such as LPI RESLO and GRIP) are supplied when
the existing soil mass has a high resistivity.
• Using the compounds can lower earth resistance/impedance.
• Compounds will require water and a mixing container.
• Follow all installation and safety instructions as supplied with products when applying the
compounds.
Bonding the Lightning Earth
Where separate earths exist eg. Structure, Power, Communications and Lightning Protection,
they need to be bonded to form an equipotential ground plane. This will stop ground loops and
potential differences arising under transient conditions.
Before bonding of these earths takes place, make sure proper authorisation is gained.
Bonding cable must be 70mm2 (2/0 AWG) minimum depending on local standards. It may be
necessary to use a Transient Earth Clamp (TEC 100) which bonds all earths to the same potential
under transient conditions.
For further information, it is advisable that local applicable standards are used, ie. IEC 61024-1,
BS 6551, AS1768-2007, NFPA 780, C22.1-98 and NEC.
Labelling
It is the responsibility of the customer/installer to label earth pits or earthing systems to local
requirements.
Installation of the HVSC Downconductor
If installing LPI HVSC, the HVSC downconductors(s) may have had the upper terminations
completed at a pre-specied end of the cable by the LPI factory before being shipped.
When removing HVSC downconductor packaging, do not use a knife or cut in any way as this can
damage the outer layer of termination.
LPI’s HVSC has an outer layer which is approximately 2mm (1/16in.) thick. Be careful not to
damage this layer.
Guardian Install Manual V12.indd 17 22/9/08 4:25:23 PM

16 Document 36 II Guardian Version 1.02 © Copyright 2008 LPI
Hauling the HVSC Downconductor
Place the HVSC downconductor cable drum close to where it is to be installed.
• Make sure that the cable drum is in a servicable condition.
• Check that the correct length of HVSC downconductor has been supplied. The length of
HVSC will be marked on the drum.
• If the HVSC downconductor has been upper terminated on the outside of the drum, then
the HVSC downconductor will need to be hauled up the structure with the drum staying on
the ground.
Figure 10.
Guardian Install Manual V12.indd 18 22/9/08 4:25:23 PM

Document 36 II Guardian Version 1.02 © Copyright 2008 LPI17
Figure 11.
• If the HVSC downconductor has been upper terminated on the inside of the drum, then
the drum has to be taken to the top or near the top of the structure, then the HVSC
downconductor can be hauled downwards from the drum to the ground.
• Any lifting slings or ropes must be securely attached.
• DO NOT haul the HVSC downconductor from the termination, see Figure 11.
• Protect the HVSC downconductor at all times when it is being moved.
Guardian Install Manual V12.indd 19 22/9/08 4:25:23 PM

18 Document 36 II Guardian Version 1.02 © Copyright 2008 LPI
HVSC Downconductor clearance holes
Before running the HVSC downconductor through any clearance holes, ensure that:
• A minimum hole diameter of 60mm (2 3/8”) is used.
• Enough protection is provided so that the HVSC downconductor is not damaged during or
after installation.
• A waterproong sealant or sealing gland should be used if the hole needs to be
weatherproof.
Routing
The routing of the HVSC downconductor needs to follow these guidelines:
• The route of the HVSC downconductor should be as set out in the original design. Ensure
no structural changes such as new antenna or mast installations, air conditioning
towers or ducting has been installed.
• DO NOT double the HVSC downconductor back against itself after changes of direction, ie.
180°.
• The HVSC downconductor may be installed internally or externally on the structure.
• The HVSC downconductor should be installed as close (ush) as possible to the structure.
• Minimise the number of bends and use the most direct route to ground.
• Minimise strain on the HVSC downconductor.
• Ensure minimum bend radius maintained ›500mm (20in.).
• Parallel routing with other services – Minimum separation = 2m. See Figure 12 on page 19.
• If the HVSC downconductor has to cross other services make sure it crosses at right angles
using a conduit that extends at least 1m past either side of the existing service.
• The lower end of the HVSC downconductor must terminate close to the initial injection
point of the lightning earth.
• Be sure to allow for enough slack in the HVSC at the top end for connection to the Guardian
CAT Terminal and the raising of the mast.
