1. Important safety information
To prevent fire and explosions when installing or operating the PTP 600 Series
in hazardous locations, observe the instructions in this guide.
Limiting EIRP
Installation and operation of these products in locations where exposure to hazardous
gasses is expected will be subject to limiting the EIRP from the PTP600-ATEX/Hazloc
series of radio products.
Exceeding the EIRP limits will compromise safety. Please refer to the certificates
referenced in 2 Allowed operating envelope for special conditions of safe use.
The EIRP limit depends on the gas class/gas group prevalent in the operating location.
Installing connectorized ODUs
As shipped by the manufacturer, the equipment is set to meet the most stringent EIRP
limits assuming an integrated antenna. Special care is therefore needed when operating
connectorized versions of the radio with external antennas.
PIDU
The PIDU is intended for indoor use only and is not weatherproof. It has not been
certified for use in the hazardous environments and must be located in a safe
environment.
PTP-SYNC
The PTP-SYNC unit is NOT approved for use in hazardous environments and cannot be
used to connect to an ODU in the hazardous environments. If there is a need to provide
a synchronized link, contact Cambium for assistance.
GPS unit
The GPS unit recommended for use with the PTP-SYNC unit must also be located in a
safe environment. If that is not possible, then the GPS unit must not be deployed. In
these circumstances, the timing reference for synchronized units must be obtained from
either the low level 1 pps signal (via the coaxial interface) or from the timing reference
of one of the ODUs. Details may be found in the PTP 600 Series User Guide.
Checking labels
Only those products marked with the qualification labels shown in Part numbers and
product labels on page 5 may be used in hazardous locations.

4. Installation and operating requirements
General requirements
ATEX regulatory environments
Installation should be in accordance with the requirements of EN60079-14 as
applicable.
Hazloc regulatory environments
Installation should be in accordance with the National Electrical Code (NEC) and
relevant OSHA standard.
Warnings
Before installing these products, read 1 Important safety information.
EIRP limitations for radio regulations
All the PTP 600 Series radio products have to meet local radio regulations, whether or
not the products are the ATEX/Hazloc approved versions. The local radio regulations
do vary considerably around the world; Cambium provides a set of region codes or
license keys to meet those requirements.
Cambium PTP 600-ATEX/Hazloc Series radio products that are currently released
operate in the 5.4 GHz and 5.8 GHz bands. These products are shown in Table 3 along
with the EIRP limits applicable to the frequency band and region from the local radio
regulations.
Table 3 Radio regulatory EIRP limits for unlicensed 5 GHz bands
Region EIRP limits at 5.4 GHz EIRP limits at 5.8 GHz
USA 1 W maximum with ≥ 20 MHz No EIRP limit for point-to-point
channel bandwidth. use.
EIRP density limited to
50 mW/MHz.
Europe 1 W maximum with ≥ 20 MHz 4 W maximum with ≥ 20 MHz
channel bandwidth. channel bandwidth.
EIRP density limited to EIRP density limited to
50 mW/MHz. 200 mW/MHz.
See (*1).
(*1) The radio regulations for this band are not harmonized across Europe. In general
the limit is 4 W with an additional constraint of 200 mW/MHz. However, in some
countries the total EIRP is limited to 2 W and in one country 200 W EIRP is allowed.
phn-2527_001v000 (Feb 2012) Page 10

14. 4. Installation and operating requirements PTP 600 Series Hazardous Location Guide
Regulatory EIRP limits for hazardous locations
The ATEX and Hazloc standards limit the EIRP as shown in Table 4.
Table 4 EIRP limits from ATEX and Hazloc standards
Gas group Typical gas type Maximum EIRP
(Watt)
ATEX Hazloc
IIA D Propane 6
IIB C Ethylene 3.5
IIC B Hydrogen 2
IIC A Acetylene 2
Overall EIRP Limits
When installed and operating, the equipment EIRP transmitted has to comply with both
the local radio regulations and the regulations for hazardous locations. From the
above, it is clear that:
• Operation at 5.4 GHz is limited to 1 W EIRP by the Local Radio Regulations.
• Operation at 5.8 GHz is limited by:
o The regulations for hazardous locations when deployed in the USA.
o A combination of the two regulations when deployed in Europe.

5. Installing integrated PTP 600 units
PTP 54600-ATEX/Hazloc integrated
All PTP54600-ATEX/Hazloc Series radio products shipped with integrated antennas will
have the product set in the factory to a maximum EIRP of 1 W. At lower channel
bandwidths than 20 MHz, the EIRP density regulation of 50 mW/MHz will be set as the
default.
There will be no facility provided for the installer or operator to increase the EIRP or
EIRP density levels (the installer or operator will be allowed to set lower levels).
PTP 58600-ATEX/Hazloc integrated
All PTP58600-ATEX/Hazloc Series radio products shipped with integrated antennas will
have the product set in the factory to a maximum EIRP of 2 W. The installer or
operator will be allowed to contact Cambium and request an alternative region code to
allow operation at higher EIRP levels for use in areas with ATEX gas groups IIA or IIB,
or Hazloc gas groups C or D.
CE-marked PTP 58600-ATEX/Hazloc devices
The installer or operator will be allowed to use alternative region codes that provide
higher EIRP levels up to the 6 W hazard limit. Table 5 specifies the maximum EIRPs
supported for each gas group.
Table 5 Overall EIRP limits for CE-marked PTP 58600-ATEX/Hazloc devices
Gas group Maximum EIRP Notes
(Watt)
ATEX group IIA Hazloc group D 6W (*1)
ATEX group IIB Hazloc group C 3.5 W (*1)
ATEX group IIC Hazloc groups B 2W
ATEX group IIC Hazloc groups A 2W
(*1) The region code provided by Cambium will be country-specific and may limit this
power to 2 W.
FCC-marked PTP 58600-ATEX/Hazloc devices
The installer or operator will be allowed use alternative region codes that provide
higher EIRP levels up to the 6 W hazard limit. The maximum EIRPs supported will be
as shown in Table 4.
phn-2527_001v000 (Feb 2012) Page 12

16. PTP 600 Series Hazardous Location Guide
6. Installing connectorized PTP 600 units
Factory-set power limits
All PTP54600-ATEX/Hazloc and PTP58600-ATEX/Hazloc Series radio products shipped
with a connector plate will have the product set in the factory to a power level that
would provide maximum EIRP of 1 W if the unit had been fitted with an integrated
antenna. At lower channel bandwidths than 20 MHz, the EIRP density regulation of
50 mW/MHz will be set as the default.
Procedure for higher gain antennas
When the device is installed with higher gain antennas, follow this procedure to set a
safe and legal EIRP level:
1 Obtain from the supplier or Cambium the license key applicable to the required
gas group.
2 Ensure that the antennas are not connected.
3 Power up the unit and display the Software License Key web page. Update the
license key as described in Chapter 6 of the PTP 600 Series User Guide and
reboot the unit as shown.
4 When the unit is again operational, display the Installation web page (see
Chapter 6 of the PTP 600 Series User Guide).
5 Note the gain of the external antenna(s) being used.
The PTP Series radio products are designed to operate with dual polarized
(V+H) antennas. However, there are circumstances where two spatially
diverse single polarization antennas are preferred.
6 Note the cable loss in dB of each of the coaxial cables connecting the antenna(s)
to the ODU. Choose the median of the two values if there is any significant
difference.
7 Go to Step 2 of the Installation Wizard and enter the noted values for antenna
gain and cable loss. Select Submit Wireless Configuration to store the
information and power off the unit.
When the unit is next powered up, the maximum transmit power will be automatically
set by the operating software to meet the ATEX/Hazloc limits for the appropriate gas
group.
For all PTP54600-ATEX/Hazloc connectorized devices and all CE-marked PTP58600-
ATEX/Hazloc connectorized devices, it is still the responsibility of the installer to then
follow the procedures in Chapter 6 of the PTP 600 Series User Guide to set the EIRP to
meet the applicable radio regulations.
