PTP 500 and PTP 300 Series User Guide
phn-2511_005v000 (Mar 2013) I
Safety and regulatory information
This section describes important safety and regulatory guidelines that must be observed by
personnel installing or operating PTP 500 equipment.
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.

Safety and regulatory information
II phn-2511_005v000 (Mar 2013)
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 Plus 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 terminals in the PIDU.
•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).
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 (with a multimeter) to test a cable with an ODU attached, not a
cable with a PIDU attached. 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.

PTP 500 and PTP 300 Series User Guide
phn-2511_005v000 (Mar 2013) III
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.
The minimum separation distances for each frequency variant are specified in Calculated
distances and power compliance margins on page 4-28.
Important regulatory information
The PTP 500 product is certified as an unlicensed device in frequency bands where it is not
allowed to cause interference to licensed services (called primary users of the bands).
Radar avoidance
In countries where radar systems are the primary band users, the regulators have
mandated special requirements to protect these systems from interference caused by
unlicensed devices. Unlicensed devices must detect and avoid co-channel operation with
radar systems.
The PTP 500 provides detect and avoid functionality for countries and frequency bands
requiring protection for radar systems.
Installers and users must meet all local regulatory requirements for radar detection. To
meet these requirements, users must set the correct license key and region code during
commissioning of the PTP 500. If this is not done, installers and users may be liable to civil
and criminal penalties.
Contact the Cambium helpdesk if more guidance is required.

Safety and regulatory information
IV phn-2511_005v000 (Mar 2013)
USA and Canada specific information
The USA Federal Communications Commission (FCC) has asked manufacturers to
implement special features to prevent interference to weather radar systems that operate
in the band 5600 MHz to 5650 MHz. These features must be implemented in all products
able to operate outdoors in the band 5470 MHz to 5725 MHz.
Manufacturers must ensure that such radio products cannot be configured to operate
outside of FCC rules; specifically it must not be possible to disable or modify the radar
protection functions that have been demonstrated to the FCC.
In order to comply with these FCC requirements, Cambium supplies variants of the
PTP 500 for operation in the USA or Canada. These variants are only allowed to operate
with license keys and region codes that comply with FCC/IC rules. In particular, operation
of radio channels overlapping the band 5600-5650 MHz is not allowed and these channels
are permanently barred.
In addition, other channels may also need to be barred when operating close to weather
radar installations.
To ensure compliance with FCC rules (KDB 443999: Interim Plans to Approve UNII
Devices Operating in the 5470 - 5725 MHz Band with Radar Detection and DFS
Capabilities), follow the instructions in Avoidance of weather radars (USA only) on page
2-5.
Other variants of the PTP 500 are available for use in the rest of the world, but these
variants are not supplied to the USA or Canada except under strict controls, when they are
needed for export and deployment outside the USA or Canada.
Specific expertise and training required for professional installers
To ensure that the PTP 500 is installed and configured in compliance with the
requirements of Industry Canada and the FCC, installers must have the radio engineering
skills and training described in this section. This is particularly important when installing
and configuring a PTP 500 system for operation in the 5.4 GHz UNII band.
Avoidance of weather radars
The installer must be familiar with the requirements in FCC KDB 443999. Essentially, the
installer must be able to:
•Access the FCC data base of weather radar location and channel frequencies.
•Use this information to correctly configure the product (using the GUI) to avoid
operation on channels that should be barred according to the guidelines that are
contained in the KDB and explained in detail in this user guide.

PTP 500 and PTP 300 Series User Guide
phn-2511_005v000 (Mar 2013) V
External antennas
When using a connectorized version of the product (as compared to the version with an
integrated antenna), the conducted transmit power must be reduced to ensure the
regulatory limit on transmitter EIRP is not exceeded. The installer must have an
understanding of how to compute the effective antenna gain from the actual antenna gain
and the feeder cable losses.
The product GUI automatically applies the correct conducted power limit to ensure that it
is not possible for the installation to exceed the EIRP limit, when the appropriate values
for antenna gain and feeder cable losses are entered into the GUI.
Ethernet networking skills
The installer must have the ability to configure IP addressing on a PC and to set up and
control products using a web browser interface.
Lightning protection
To protect outdoor radio installations from the impact of lightning strikes, the installer
must be familiar with the normal procedures for site selection, bonding and grounding.
Installation guidelines for the PTP 500 can be found in Chapter 2: Planning considerations
and Chapter 5: Installation.
Training
The installer needs to have basic competence in radio and IP network installation. The
specific requirements applicable to the PTP 500 should be gained by reading Chapter 5:
Installation and Chapter 6: Configuration and alignment and by performing sample set
ups at base workshop before live deployments.
