1Introduction
The iWAP107 and iRFID107 are ATEX and IECEx approved Zone 1 Wireless Device
Enclosures with intrinsically safe RF outputs; they are designed to allow the
deployment of wireless networks in hazardous areas. The concept allows
installation of equipment from leading WLAN vendors such as Cisco, Aruba,
Aeroscout and Motorola. Each type of Access Point or RF transmitting device is
rigorously checked and tested by Extronics to ensure conformity to the latest
standards. This means that the user may select the vendor of their choice when
extending a WLAN to hazardous areas. However equipment not previously
approved will require assessment to determine its suitability.
The intrinsically safe RF outputs of the iWAP107/iRFID107 allows users to choose
any antenna for use with their wireless hardware e.g. Extronics iANT2xx range of
high quality rugged outdoor antennas. Any antennas not listed in the Extronics
range must be assessed to ensure they meet the requirements for installation of
non-electrical equipment in hazardous areas. This assessment can be provided by
Extronics or done by the user. Up to eight antennas can be utilized, allowing the
MIMO functionality of the latest compatible wireless access points to be
implemented, providing optimum coverage and maximum data throughput on
Chemical Plants, Oil Refineries or Oil & Gas Platforms. Optional features include
surge arrestors for lightning suppression in outdoor installations and single mode
or multimode fibre optic inputs to allow for extended Ethernet link distance.

3.10.1 Example of RF threshold power calculation
The following example shows how the RF threshold power may be calculated:
Maximum transmitter output power (from transmitter datasheet) = 20dBm (100mW)
Coaxial cable loss = 2dB
Antenna gain = 5dBi
Threshold power = 20dBm –2dB + 5dBi
Threshold power = 23dBm (200mW)
Warning! Due to the typical maximum transmit power of UHF readers
(in the case of iRFID107), customers may need to install
attenuators or excess lengths of RF cable to comply with
maximum RF thresholds. Contact Extronics for more
information.
3.11 Antenna Requirements
Antennas connected to the iWAP107/iRFID107 Intrinsically Safe RF outputs must be
assessed as ‘simple apparatus’ in accordance with IEC 60079-11. Antennas supplied by
Extronics for use with the iWAP107/iRFID107 already meet these requirements. It is
possible to assess other antennas for this purpose, contact Extronics for details.
3.12 Antenna Installation
Antennas approved by Extronics for use with the iWAP107/iRFID107 may either be fitted
directly to the RF connectors of the iWAP107/iRFID107, or via a length of coaxial cable.
If antennas are sited remotely from the iWAP107/iRFID107 flameproof enclosure, any
metallic parts of the antennas must be isolated from earth by > 500Vr.m.s, to prevent
hazardous earth currents from flowing in the coaxial cable.

3.13 Prevention of Electrostatic Charging
The iWAP107/iRFID107 enclosure can build up electrostatic charge on its surfaces, so the
following steps are to be followed to reduce static charge build up:
Static charge build up should be reduced by:
•Connecting the enclosure to a suitable earth point
•Cleaning off surface dust using a damp cloth
•Not installing into areas where high airflow can occur
3.14 Additional Labels & Non-Metallic Materials
Additional labels may be fitted to the enclosure. Label material may be stainless steel or
any other non-metallic material. To prevent an electro-static risk, non-metallic materials
must only be cleaned with a damp cloth.
If non-metallic materials are used, consideration should be given to the following:
•Control of environmental humidity to minimise the generation of static electricity.
•Protection from direct airflow causing a charge transfer.
•Touch with an insulation object.
•Means to continuously drain off electrostatic charges.
Refer to IEC 60079 Part 0 for further information
