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.

Keep this user manual safe and in the vicinity of the device. All persons who have to work on
or with the device should be advised on where the manual is stored.
2.2 Special Conditions of Safe Use
2.2.1 ATEX
•The apparatus is not capable of withstanding the 500V insulation test required by clause 6.8.1 of
EN60079-15:2005. This must be taken into account when installing the apparatus. Refer to
manufacturers’ instruction manual for guidance.
•All cable glands, blanking elements and thread adapters shall be certified to a minimum II 3 G IIC, II
•2 D IIIC, provide a minimum degree of protection of IP64 and have an ambient range suitable for
installation.
•External antenna connections must be shielded from ultraviolet radiation with either a cap or an antenna.
•The iSOLATE500 or iSOLATE501 enclosure must be earthed through its mounting to an earthed chassis
or with an earth bond wire with a cross section area of at least 4mm².
•It is considered inappropriate to provide conventional IS parameters for this equipment. For connection
to external antenna refer to the information in the manufacturers’ instruction manual for clarification of
the antenna requirements and calculation of the RF output power.

Warning! Changes in the design and modifications to the equipment are not
permitted. Changing of the pre-installed wireless devices is NOT
permitted.
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! The iWAP202 MUST be earthed. Refer to Section [earthing] for details.
Warning! The IWAP202 shall be operated as intended and only in an undamaged
condition.
Warning! The IWAP202 must not be stored or operated outside of its rated
temperature range as stated on the ATEX certificates.
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 for ATEX Category 2G and ATEX Category 2D equipment,
and must not compromise the IP66 rating of the iWAP202 enclosure.
Warning! The nylon washers on the underside of the enclosure lid must be used
with the gasket to maintain the IP rating of the enclosure.
Warning! Although antennas connected to the Intrinsically Safe RF outputs of the
iWAP202 may be installed in Zone 0, Zone 1 or Zone 20 hazardous areas,
the iWAP202 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)
III – 6W (+37.7dBm)
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
Information 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.

For example:
If you have ordered 1 N-type connector for Radio 1, and 2 N-type connectors for
Radio 2. Then R1-A will be connected to antenna port 1 of Radio 1, R2-A will be
connected to antenna port 1 of Radio 2, and R2-B will be connected to antenna port
2 of Radio 2 for any manufacturers wireless access point.
