Important safety information
To prevent loss of life or physical injury, observe the safety guidelines in this
section.
Power lines
Exercise extreme care when working near power lines.
Working at heights
Exercise extreme care when working at heights.
Grounding and protective earth
The Outdoor Unit (ODU) must be properly grounded to protect against lightning. It is
the user’s responsibility to install the equipment in accordance with national
regulations. In the USA, follow Section 810 of the
National Electric Code, ANSI/NFPA
No.70-1984
(USA) . In Canada, follow Section 54 of the Canadian Electrical Code . These
codes describe correct installation procedures for grounding the outdoor unit, mast,
lead-in wire and discharge unit, size of grounding conductors and connection
requirements for grounding electrodes. Other regulations may apply in different
countries and therefore it is recommended that installation of the outdoor unit be
contracted to a professional installer.
PIDU
Always use the Cambium Power Indoor Unit Plus (PIDU Plus PTP 300/500/600 Series)
to power the ODU. Failure to use the Cambium supplied PIDU could result in
equipment damage and will invalidate the safety certification and may cause a safety
hazard.
Alternative DC supplies
If an AC supply is not required or an additional back up DC supply is required, the DC
supply is connected to the PIDU DC IN terminals. This is the only method of supplying
external DC to the ODU. The DC supply must comply with the following requirements:
•The voltage and polarity is correct and is applied to the correct PIDU terminals.
•The power source is rated as Safety Extra Low Voltage (SELV).
•The power source is rated to supply at least 1A continuously.
•The power source cannot provide more than the Energy Hazard Limit as defined by
IEC/EN/UL60950-1, Clause 2.5, Limited Power (The Energy Hazard Limit is 240VA).

Important safety information PTP 500 Installation Guide
phn-2508_005v000 (Mar 2013) Page 3
Powering down before servicing
Always power down and unplug the equipment before servicing.
Lightning protection unit (LPU)
Do not remove the LPU printed circuit board when the LPU is connected to the power
supply, as high voltages are present.
Drop cable tester
The drop cable tester must NEVER be used at the ODU end connected to power from
the PIDU. It must only be used at the bottom of the mast with a multimeter. This is
because the PIDU voltage exceeds the limit allowed in some countries for safe handling
in wet conditions and therefore may create a safety hazard.
Primary disconnect device
The main power supply is the primary disconnect device.
External cables
Safety may be compromised if outdoor rated cables are not used for connections that
will be exposed to the outdoor environment.
Grounding PTP-SYNC
In order to meet the safety requirements for deployment in Australia and New Zealand
(AS/NZS 60950-1), the PTP-SYNC unit, if deployed, must be grounded to a Protective
Ground in accordance with Local Electrical Regulations.
RF exposure near the antenna
Strong radio frequency (RF) fields will be present close to the antenna when the
transmitter is on. Always turn off the power to the ODU before undertaking
maintenance activities in front of the antenna.
Minimum separation distances
Install the ODUs so as to provide and maintain the minimum separation distances from
all persons. For minimum separation distances, see the
PTP 500 and PTP 300 Series
User Guide
.

3. Grounding and lightning protection
Electro-magnetic discharge (lightning) damage is not covered under warranty.
The recommendations in this document and in the
PTP 500 and PTP 300
Series User Guide
, when followed correctly, give the user the best protection
from the harmful effects of EMD. However 100% protection is neither implied
nor possible.
Lightning protection zones
The rolling sphere method is used to determine where it is safe to mount equipment.
An imaginary sphere, typically 50 meters in radius, is rolled over the structure. Where
the sphere rests against the ground and a strike termination device (such as a finial or
ground bar), all the space under the sphere is considered to be in the zone of protection
(Zone B). Similarly, where the sphere rests on two finials, the space under the sphere is
considered to be in the zone of protection.
Assess locations on masts, towers and buildings to determine if the location is in Zone A
or Zone B:
•Zone A: In this zone a direct lightning strike is possible. Do not mount equipment in
this zone.
•Zone B: In this zone, direct EMD (lightning) effects are still possible, but mounting
in this zone significantly reduces the possibility of a direct strike. Mount equipment
in this zone.
Never mount equipment in Zone A. Mounting in Zone A may put equipment,
structures and life at risk.

3. Grounding and lightning protection PTP 500 Installation Guide
phn-2508_005v000 (Mar 2013) Page 11
General protection requirements
Apply the practices and procedures detailed in the relevant national standards to all
new site build activities. The following requirements are described in greater detail in
the
PTP 500 and PTP 300 Series User Guide .
Basic requirements
The following basic protection requirements must be met:
•The equipment (ODU) must be in Zone B.
•The ODU must be grounded to the supporting structure.
•A lightning protection unit (LPU) must be installed within 600 mm (24 in) of the
point at which the drop cable enters the building or equipment room.
•The drop cable must be bonded to the supporting structure in order to prevent
lightning creating a potential between the structure and cable, which could cause
arcing, resulting in fire risk and damage to equipment.
•The drop cable shield must be grounded at the building entry point.
•The drop cable must not be laid alongside a lightning air terminal.
•All grounding cables must be minimum size of 10 mm2csa (8AWG), preferably
16 mm2csa (6AWG), or 25 mm2csa (4AWG).
Grounding cable requirements
When routing, fastening and connecting grounding cables, the following requirements
must be met:
•Grounding conductors must be run as short, straight and smooth as possible, with
bends and curves kept to a minimum.
•Grounding cables must not be installed with drip loops.
•All bends must have a minimum radius of 203 mm (8 in) and a minimum angle of
90°. A diagonal run is preferable to a bend, even though it does not follow the
contour or run parallel to the supporting structure.
•All bends, curves and connections must be routed towards the grounding electrode
system, ground rod, or ground bar.
•Grounding conductors must be securely fastened.
•Braided grounding conductors must not be used.
•Approved bonding techniques must be used for the connection of dissimilar metals.

3. Grounding and lightning protection PTP 500 Installation Guide
phn-2508_005v000 (Mar 2013) Page 12
Mast or tower installation
For mast or tower installations, the following additional requirements must be met:
•The equipment must be lower than the top of the tower or its lightning air terminal.
•The metal tower or mast must be correctly grounded.
•A grounding kit must be installed at the first point of contact between the drop cable
and the tower, near the top.
•A grounding kit must be installed at the bottom of the tower, near the vertical to
horizontal transition point, bonded to the tower or its ground bar (TGB).
•If the tower is greater than 61 m (200 ft) in height, an additional grounding kit must
be installed at the tower midpoint and as necessary to reduce the distance between
ground kits to 61 m (200 ft) or less.
•In high lightning prone geographical areas, additional ground kits should be
installed at spacing between 15 to 22 m (50 to 75 ft). This is especially important on
towers taller than 45 m (150 ft).

4. Preparing for installation
Safety precautions before installation
All national and local safety standards must be followed while developing a site,
installing equipment, or performing maintenance.
Ensure that personnel are not exposed to unsafe levels of RF energy. The units
start to radiate as soon as they are powered up. Respect the safety standards
defined in the
PTP 500 and PTP 300 Series User Guide
.
Never work in front of the antenna when the ODU is powered.
Before connecting or disconnecting the drop cable from the PIDU or ODU,
always power down the PIDU.
The installation must meet the requirements in 3Grounding and lightning protection.
Preparing personnel
In no event shall Cambium Networks be liable for any injury to any persons or any
damage caused during the installation of the Cambium PTP 500. Ensure that only
qualified personnel undertake the installation of a PTP 500 Series link. Ensure that all
safety precautions can be observed.
Preparing inventory
Perform the following inventory checks:
•Check that an installation report is available, based on the principles described in
the
PTP 500 and PTP 300 Series User Guide .
•Check that the correct components are available, as described in 1 Inventory.
Preparing tools
Check that following specific tools are available, in addition to general tools:
•13 mm wrench and 22 mm wrench for use with the glands.
•RJ45 crimp tool (it must be the correct tool for the type of RJ45 being used).
•Personal Computer (PC) with 100 BaseT Ethernet.

5. Installing the ODU
Checks and safety precautions
To prevent failure of the assembly, take the following precautions:
Do not remove the pre-fitted mounting bracket.
Do not mount the ODU on poles with diameter less than 50 mm (2 in) or
greater than 75 mm (3 in).
Check that the integrated lifting eye and its fixing are not damaged in any way
and have not been exposed to a shock loading due to a fall.
Do not reverse the rear bracket strap:
.
Check that the ODU is pre-fitted with a mounting bracket (designed to ease installation)
and with a ground cable:

5. Installing the ODU PTP 500 Installation Guide
phn-2508_005v000 (Mar 2013) Page 16
Selecting a position for the ODU (connectorized)
Mount a connectorized ODU in a position that gives it maximum protection from the
elements, allows easy access to the cables, and allows antenna cable lengths to be
minimized. If separate antennas are being deployed, it is not necessary to mount the
ODU at the mid-point between the antennas.
Mounting the ODU
To mount the ODU, proceed as follows:
1 Attach the ODU bracket strap to the pole using M8 x 40 mm or M8 x 70 mm
bolts, M8 flat washers and M8 coil washers. Tighten to ensure the assembly
grips, but can be adjusted on the pole.
2 Use the integrated lifting eye to hoist the ODU up to the bracket, observing the
safety precautions listed in Checks and safety precautions on page 15.
3 Offer the ODU (with pre-fitted mounting bracket) to the bracket strap and affix
using the captive M8 bolt. Tighten to ensure the assembly grips, but can be
adjusted on the pole.
4 Adjust the elevation and azimuth of the unit to achieve an approximate visual
alignment (does not apply to connectorized ODUs). Tighten all three bracket
bolts to the required torque settings of 14 Nm (11 lb ft).
Do not over-tighten the bolts, as this may lead to failure of the assembly.

5. Installing the ODU PTP 500 Installation Guide
phn-2508_005v000 (Mar 2013) Page 17
5 Connect the ODU ground cable to the to the grounding system, within 0.3 meters
(1 ft) of the ODU bracket and on the same metal (if necessary, remove paint and
apply anti-oxidant compound first).
Do not attach grounding cables to the ODU mounting bracket bolts, as this
arrangement will not provide full protection.
6 To prevent corrosion and possible loss of ground continuity, weatherproof the
grounding point.
Installing connectorized antennas
To mount and connect the antennas, proceed as follows:
1 Mount the antenna according to manufacturer’s instructions. When using
separate antennas to achieve spatial diversity, mount one with Horizontal
polarization and the other with Vertical polarization.
2 Connect the ODU to the antenna with cables of type LMR100, LMR200, LMR300,
LMR400 or LMR600. Use the ODU “V” interface for vertical polarization and the
“H” interface for horizontal polarization.
When using separate antennas to achieve spatial diversity, the antenna cables
will be disconnected from the ODU during the alignment procedure. Therefore,
do not weatherproof the ODU antenna connectors until antenna alignment is
complete.
3 If the ODU is mounted indoors, install lightning arrestors at the building entry
point. Connect the lighting arrestors to the master ground bar of the building.
