1 Introduction The Hazardous Environment Enclosure is an ATEX and IECEx
approved Zone 1 access point enclosure with intrinsically safe
RF outputs; it is 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, and Meraki. Each type of access point or RF transmitting device is rigorously
checked and tested by Ventev 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 Hazardous Environment Enclosure allows users
to choose any antenna for use with their wireless hardware e.g., Ventev’s range of
high quality rugged outdoor antennas. Up to eight antennas can be utilized, allowing
the MIMO functionality of the latest compatible Wi-Fi 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.

work on or with the device should be advised on where the manual is stored.
2.2 Special Conditions for Safe Use
2.2.1 ATEX/IECEx
1. Contact Ventev for information on the dimensions of the flameproof joints.
2. The RF output is only to be connected to an antenna suitable for the hazardous location; refer to associated
RF galvanic isolator iSOLATE501 equipment certificate (IECEx trc 15.0015X/TRAC15ATEX0050x) or iSOLATE500
equipment certificate (IECEx BAS 13.0064X/Baseefa13ATEX0112X), and associated instructions.
3. If the RF output connector is not intended to be connected to a cable and/or antenna, the output connector must
be capped.
4. Flamepath joints are not intended to be repaired.
5. Breather/drain valves may be fitted providing that they are suitably ATEX/IECEx Ex db equipment certified.
6. Cables connected to the optical input shall be installed according to IEC 60079-14 K.3 and be suitably
mechanically protected.

Warning!
Installation of the Hazardous Environment Enclosure must be performed in accordance
with IEC 60079-14 and IEC 60079-25. Maintenance and inspection must be performed
in accordance with IEC 60079- 17.
Warning!
Installation of the Hazardous Environment Enclosure is only to be performed by skilled
electricians and instructed personnel in accordance with national legislation.
Warning!
The Hazardous Environment Enclosure contains INTRINSICALLY SAFE circuits.
Warning!
The Hazardous Environment Enclosure Intrinsically Safe RF output ports are located in
the positions shown in Section 3.3. Only antennas in accordance with Section 3.11 may
be connected to these ports. Refer to Section 3.12 for antenna installation requirements.
Warning!
The Hazardous Environment Enclosure MUST be earthed. Refer to Section [earthing] for details.
Warning!
The Hazardous Environment Enclosure must NOT be installed in hazardous areas
requiring Category 1, M1, or M2 equipment.
Warning!
Although antennas connected to the Intrinsically Safe RF outputs of the Hazardous
Environment Enclosure may be installed in hazardous areas requiring Category 1
equipment, the Hazardous Environment Enclosure flameproof must NOT be installed
in these environments.
Warning!
The Hazardous Environment flameproof enclosure must NOT be opened when an
explosive gas or dust atmosphere is present or when the equipment is energized.
Warning!
The Hazardous Environment flameproof enclosure lid must be secured only with the
bolts supplied and these must be tightened to the correct torque value. See Section
3.2.2 for details. Contact Ventev for spare bolts.

Warning!
The Hazardous Environment flameproof enclosure must only be fitted with suitably
approved cable entry devices. See Section 3.3 for details.
Warning!
Do not exceed the RF Threshold Power for the equipment group in which the Hazardous
Environment Enclosure 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)
See Section 3.10.1 for an example of how to calculate the RF Threshold Power.
Warning!
The Hazardous Environment Enclosure must not be modified in any way.
Warning!
There are no user-serviceable parts below the top plate of the Hazardous Environment
Enclosure. See Section 3.5 for details. Always refer service enquiries to Ventev.
Warning!
Hazardous voltages are present within the Hazardous Environment Enclosure.
Warning!
Hot surfaces may be present within the Hazardous Environment Enclosure. Observe the
warning labels fitted.
Warning!
Optical radiation hazards may be present within the Hazardous Environment Enclosure.
Observe the warning labels fitted.
Warning!
The Hazardous Environment Enclosure may weigh up to 70Kg. Exercise care when
handling and mounting.

Warning!
DO NOT lift the Hazardous Environment Enclosure using the threaded entries, N-type
RF connectors, or door bolts. Lift only using suitably approved slings, fitted by suitably
qualified personnel.
Warning!
When a device is fitted with a coin cell and the coin cell is required to be replaced, it
shall only be fitted with the exact same type of coin cell as marked on the device.
Warning!
The Hazardous Environment stainless steel enclosure weighs approximately 70Kg.
Exercise care when handling and use suitable mounting points and structures. Mount
the enclosure ONLY using the mounting points shown.
Important
Always re-apply a thin layer of Loctite 8104 or Loxeal GS9 silicone grease to the
enclosure flame paths whenever the Hazardous Environment flameproof enclosure is
opened. This is required to maintain the IP rating of the enclosure.
Important
Do not exceed the power supply parameters specified on the Hazardous Environment
Enclosure external rating plate.
Important
Ensure that NO TOOLS come into contact with the flamepath of the enclosure, as this
may cause irreparable damage and render the unit unsafe.
Important
Ensure that only the correct fiber transceiver format/power is connected to the
Hazardous Environment Enclosure. Damage to the Hazardous Environment Enclosure
fiber interface or customer equipment may occur if the wrong format/excessive optical
power is used.
Important
Only replace the fuse with the same value and type indicated on the internal fuse
identification label.
