WARNING
To prevent loss of life or physical injury, observe the safety guidelines
in this section.
Power lines
Exercise extreme care when installing antennas 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
No.70-1984
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.
(USA). In Canada, follow Section 54 of the
National Electric Code, ANSI/NFPA
Canadian Electrical Code

Safety and Regulatory
Using the correct power supply
Always use the Motorola Power over Ethernet injector unit (PoE power supply) or
Powered Indoor Unit (PIDU Plus) to power the ODU. Failure to use the correct power
supply could result in equipment damage and will invalidate the safety certification
and may cause a safety hazard.
Alternative DC supply
If the PTP 250 is to be powered from a DC supply (either as the primary power source
or as a backup to the AC supply), the DC supply must be input to the ODU via a PIDU
(not a PoE power supply). The DC supply must be connected to the PIDU DC IN
terminals. 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 1 A 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.
Non-Motorola power supply
Safety may be compromised if a different power supply is used than the one supplied
by Motorola as part of the system.

Safety and Regulatory
Drop cable tester
The drop cable tester must NEVER be used at the ODU end connected to power from
the PoE power supply. It must only be used at the bottom of the mast with a
multimeter. This is because the PoE power supply 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.
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 pag
e 4-25.

Safety and Regulatory
Important regulatory information
Operation of the PTP 250 product involves its use 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 some countries radar systems are the primary users and the regulators have
devised special requirements to protect their operation from interference caused by
unlicensed devices. The unlicensed devices are required to detect the presence of
radar systems and avoid co-channel operation with the radar systems.
The PTP 250 system provides detection and avoidance functionality for countries and
frequency bands requiring protection for radar systems.
Installers and users are reminded that they must follow local regulations with regard
to any requirements for radar detection as well as transmitted power level. This can
be achieved by using the correct country code for the product concerned. Failure to
follow this could leave the installer and/or user liable to civil and/or criminal penalties.
Contact the Motorola helpdesk if you are unsure about any specific areas where you
need guidance.
