1: Introduction
Ventev’s Class 1 Div. II Enclosure has been designed to enable the deployment of
popular wireless access points, radio, and communications equipment, or Industrial
Internet of Things (IIoT)/ Industry 4.0 devices in Zone 2 / Division 2 hazardous areas
(gas or dust).
The RF outputs of the enclosure are galvanically isolated to make them intrinsically
safe, allowing users to choose non-certified antennas for use with their wireless
hardware.
A range of wireless devices from multiple manufacturers, including Cisco, Meraki,
and Aruba, have been assessed by our engineers, following the guidelines of our
Notified Body, as suitable for use in the Ventev Class 1 Div. II Enclosure System and
complying with all regulations.
With IP66 / Type 4 (NEMA standards) ingress protection and a Marine grade copper-
free aluminium alloy, e-coat with epoxy powder coated enclosure, the Ventev Class
1 Div. II Enclosure System is suitable for a wide variety of industrial and off-shore
locations including chemical and pharmaceutical plants, oil refineries, FPSOs, and
oil and gas platforms.

in the positions shown in Section 3.4. Only antennas in accordance with Section 3.12 may
be connected to these ports. Refer to Section 3.13 for antenna installation requirements
The Ventev Class 1 Div. II Enclosure System MUST be earthed. It must be connected
to the plant earth system using at least one of the external bonding points, using a
minimum 4mm2 conductor. The earth cable must be installed in accordance with the
requirements of IEC 60079-14. Refer to Section 3.4 for details. The cover plate earth
bond must not be removed.
The Ventev Class 1 Div. II Enclosure System front cover plate earth bond must not be
removed.
The Ventev Class 1 Div. II Enclosure System internal power input connector has an
earth connection, which must be terminated to the protective earth conductor of the
incoming power supply..
The Ventev Class 1 Div. II Enclosure System must NOT be installed in hazardous areas
requiring Category 1, 2, M1, or M2 equipment.
The Ventev Class 1 Div. II Enclosure System enclosure must be secured only with the
bolts supplied, and these must be tightened to the correct torque value. See Section
3.3.2 for details.

Warning!
The Ventev Class 1 Div. II Enclosure System enclosure must NOT be opened when an
explosive gas or dust atmosphere is present, or when the equipment is energized.
Do not exceed the RF Threshold Power for the equipment group in which the Ventev
Class 1 Div. II Enclosure System 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 3.11.1 for an example of how to calculate the RF Threshold Power
The Ventev Class 1 Div. II Enclosure System must not be modified in any way.
Hazardous voltages are present within the Ventev Class 1 Div. II Enclosure System.
Hot surfaces may be present on the Ventev Class 1 Div. II Enclosure System enclosure –
observe any warning labels fitted.
Optical radiation hazards may be present within the Ventev Class 1 Div. II Enclosure
System enclosure – observe any warning labels fitted.
The Ventev Class 1 Div. II Enclosure System may weigh up to 55 lbs./25 kg. Exercise care
when handling and mounting.
DO NOT lift the Ventev Class 1 Div. II Enclosure System using threaded entries or N-type
RF connectors. Good manual handling practices should be followed.
User access: Normal user access to the enclosure is through the cover plate and junction box.
Special access: If the main enclosure is opened, the integrity of the main enclosure sealing
must be confirmed by a competent person.
Console port connections can only be used during setup or maintenance activities. They

Warning!
Maintenance and inspection of the Ventev Class 1 Div. II Enclosure System must be
performed in accordance with IEC 60079-17.
Although antennas connected to the Intrinsically Safe RF outputs of the Ventev Class
1 Div. II Enclosure System may be installed in a hazardous area requiring Category 1
equipment, the Ventev Class 1 Div. II Enclosure System enclosure must NOT be installed
in these environments.
Important!
There should be no need to enter the unit and change the fuse as it is resettable.
The Ventev Class 1 Div. II Enclosure System may be powered from several different
power sources, depending on its configuration. Refer to the rating plate of the unit
supplied for details.
Before setting the units to work, read the technical documentation carefully.
The latest version of the technical documentation or the corresponding technical
supplements is valid in each case.
Do not exceed the power supply parameters specified on the Ventev Class 1 Div. II
Enclosure System external rating plate.
Ensure that only the correct fiber transceiver format/power is connected to the Ventev
Class 1 Div. II Enclosure System. Damage to the Ventev Class 1 Div. II Enclosure System
fiber interface or customer equipment may occur if the wrong format/excessive optical
power is used.
Ensure that NO TOOLS come in contact with the gasket of the enclosure, as this may
cause irreparable damage and render the unit unsafe.
