About this guide This guide identifies the specific requirements that have to be met by the installer and operator of the Cambium PTP600-ATEX/Hazloc Series radio products when the products are for use in Hazardous Locations. Hazardous Locations are those covered by the ATEX regulations in Europe and the Hazloc regulations in the USA.
The normal operating and troubleshooting procedures for the PTP 600 Series are described in the PTP 600 Series User Guide, which may be downloaded from the support website.

PTP 600 Series Hazardous Location Guide
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 channel bandwidth.
No EIRP limit for point-to-point use.
EIRP density limited to 50 mW/MHz. Europe
1 W maximum with ≥ 20 MHz channel bandwidth.
4 W maximum with ≥ 20 MHz channel bandwidth.
EIRP density limited to 50 mW/MHz.
EIRP density limited to 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)

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

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 PTP58600ATEX/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.
