About this guide

This guide is supplied with PTP 650 ODUs. It describes how to install the site equipment for

PTP 650 Series links. Users of this guide require expertise in outdoor radio equipment

installation.

Safety

Warning

To prevent loss of life or physical injury, observe the below safety guidelines. In no event shall

Cambium Networks be liable for any injury or damage caused during the installation of the

Cambium PTP 650. Ensure that only qualified personnel install a PTP 650 link.

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.

PSU

Always use one of the Cambium PTP 650 Series power supply units (PSU) to power the ODU.

Failure to use a Cambium supplied PSU 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 PSU 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).

Powering down before servicing

Always power down and unplug the equipment before servicing.

Lightning protection unit (LPU)

Hazardous voltages are present within the LPU. Do not remove the insulation tape or printed

circuit board when the LPU is connected to the power supply.

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.

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.

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

Ensure that personnel are not exposed to unsafe levels of RF energy. The units start to radiate as

soon as they are powered up. Never work in front of the antenna when the ODU is powered.

Install the ODUs so as to provide and maintain the minimum separation distances from all

persons. For minimum separation distances, see the PTP 650 Series User Guide.

Before connecting or disconnecting the drop cable from the PSU or ODU, always power down

the PSU.

Grounding and lightning protection requirements

Ensure that the installation meets the requirements defined in the PTP 650 Series User Guide.

Grounding cable installation methods

When routing, fastening and connecting grounding cables, the following requirements must be

met:

•Grounding conductor runs are 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.

Siting ODUs and antennas

ODUs and external antennas are not designed to survive direct lightning strike. For this reason

they must be installed in Zone B as defined in PTP 650 Series User Guide. Mounting in Zone A

may put equipment, structures and life at risk.

Optical SFP module

The optical SFP module is a Class 1 Laser product. When installing it, observe the following

safety precautions:

•Do not look into the source of the laser beam (optical receptacle) directly or through an

optical system, as this is highly likely to damage vision.

•Always remove power from the system before the optical connection is made or unmade.

•When installing the optical interface, either cap the optical connector, or mate the connector

to an appropriate equipment connector.

•Ensure that the indoor end of the optical cable is appropriately labeled to ensure that service

personnel are aware the same Class 1 Laser hazard exists.

Typical deployment

A PTP 650 site typically consists of a high supporting structure such as a mast, tower or building

for the outdoor equipment (ODU and optional external antenna); and an equipment building or

moisture-proof enclosure for the indoor equipment (PSU).

In the basic configuration, there is only one Ethernet interface, a copper Cat5e connection from

the ODU (PSU port) to the PSU and network terminating equipment, as shown here:

Page 8

UNDER DEVELOPMENT

In more advanced configurations, there may be an optical or copper Cat5e SFP Ethernet interface

(unpowered) into the ODU (SFP port):

In more advanced configurations, there may be a copper Cat5e interface (with optional power

over Ethernet) into the ODU (AUX port):
