1 Introduction
The iWAP202 Zone 2 Access Point Enclosure is designed to deploy wireless
networks in hazardous areas. The concept allows installation of equipment from
leading WLAN vendors such as Cisco, Aruba and Firetide.
Each type of Access Point or RF transmitting device is rigorously checked and
tested by Extronics and our Notified Body to ensure conformity to the ATEX
standards and approvals. This means that Extronics can provide an OEM a
solution to enable your WLAN network devices to be installed in hazardous
areas.
The Extronics iWAP202 is designed for use with one to six standard antennas or
Extronics iANT200 series of antennas for optimum coverage on Chemical Plants,
Oil Refineries or Oil & Gas Platforms.
Optional features include surge arrestors for lightening suppression in outdoor
installations plus the option of plug and socket cable entry instead of cable
glands.

3.1.2 Power Supply
The iWAP202 may only be powered from an IEEE 802.3af POE or IEEE 802.3at
POE+ power source. The equipment rating plate identifies which power supply type
is required for a specific variant.
3.1.3 Fitting the Cables
Warning! All cables should be connected to the IWAP202 via the correct cable
gland, fitted by a competent person.
Warning! If cable glands different to those supplied by Extronics are used, these
must be M20-sized cable glands meeting the requirements of
EN 60079-0:2012 for ATEX Category 2 GD equipment, and not
compromise the IP66 rating of the IWAP202 enclosure.
Warning! The installer MUST ensure that that all cables have adequate mechanical
protection to avoid damage.

Warning! The iWAP202 frame earth is connected directly to circuits within the
enclosure. It is not capable of withstanding the 500V insulation test
required by clause 23.2.1 of EN 60079-15:2010. This must be taken into
account when installing the equipment
3.2 Intrinsically Safe RF Outputs
Warning! The iWAP202 Intrinsically Safe RF output ports are located in the
positions shown in [IS output position diagram]. Only antennas in
accordance with [antenna requirements section] may be connected to
these ports. Refer to section [antenna installation] for antenna
installation requirements.
Warning! Although antennas connected to the Intrinsically Safe RF outputs of the
iWAP202 may be installed in a hazardous areas requiring Category 1
equipment, the iWAP202 flameproof enclosure must NOT be installed in
these environments.
Warning! Do not exceed the RF Threshold Power for the equipment group in
which the iWAP202 and its antennas are to be installed; it must be
controlled in accordance with IEC 60079-0, and must not exceed the
following levels:
IIC – 2W (+33dBm)
IIB – 3.5W (+35.4dBm)
IIA – 6W (+37.7dBm)

3.3 Antenna Requirements
Antennas connected to the iWAP202 Intrinsically Safe RF outputs must be assessed
as ‘simple apparatus’ in accordance with IEC 60079-11. Antennas supplied by
Extronics for use with the iWAP202 already meet these requirements. It is possible to
assess other antennas for this purpose, contact Extronics for details.

3.4 Antenna Installation
Antennas approved by Extronics for use with the iWAP202 may either be fitted
directly to the RF connectors of the iWAP202, or via a length of coaxial cable.
If antennas are sited remotely from the iWAP202 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.
3.4.1 Setting to work
Warning! Ensure the lid is secure, correct cable glands are fitted and the
unit device correctly wired and earthed for the particular
application before applying power
Warning! Ensure that the lid gasket is clean and undamaged before fitting
the lid.
Once all cables are connected correctly, refit the enclosure lid using the four screws
previously removed. Use a torque screwdriver set to 2.5 Nm. Do not over-tighten
screws.
4 Intended Purpose Usage
Warning! Installation of the iWAP202 must be performed in accordance with
EN 60079-0, EN 60079-14 and EN 60079-25. Maintenance and inspection
must be performed in accordance with EN 60079-17.
Important Before setting the units to work read the technical documentation
carefully.
Important The latest version of the technical documentation or the corresponding
technical supplements is valid in each case.
The IWAP202 is built using modern components and is extremely reliable in
operation; however it must only be used for its intended purpose. Please note that
the intended purpose also includes compliance with the instructions issued by the
manufacturer for installation, setting up and service.
Any other use is regarded as conflicting with the intended purpose. The manufacturer
is not liable for any subsequent damage resulting from such inadmissible use. The
user bears the sole risk in such cases.
4.1 Transportation and Storage
All IWAP202 devices must be so transported and stored that they are not subjected
to any excessive mechanical stresses.

Operating Manual
12
4.2 Authorized Persons
Only persons trained for the purpose are authorized to handle the IWAP202; they
must be familiar with the unit and must be aware of the regulation and provisions
required for correct installation as well as the relevant accident prevention
regulations.
4.3 Cleaning and Maintenance
The IWAP202 and all its components require no maintenance and are self-
monitoring. All work on the IWAP202 by personnel who are not expressly qualified for
such activities will cause the guarantee to become void.
4.4 Cleaning and Maintenance Intervals
The cleaning intervals depend on the environment where the system is installed.
4.5 Aggressive substances and environments
The IWAP202 is not designed to come into contact with aggressive substances or
environments, please be aware that additional protection may be required.
4.6 Exposure to external stresses
The IWAP202 is not designed to be subjected to excessive stresses e.g. vibration,
heat, impact. Additional protection is required to protect against these external
stresses.
The IWAP202 will require additional protection if it is installed in a location where it
may be subjected to damage.
