Description
Our DE8-BC range of explosion proof enclosures is available in many sizes. They are made
of welded and machined acid resistant stainless steel 316L or painted carbon steel. Each is
expected to receive electrical components inside, making service and maintenance easy.
They can also be customized to meet each individual specific need. If necessary, multiple
enclosures can be assembled on a frame with or without combined Ex e junction boxes.
The enclosures can be delivered fully equipped according to customer’s requirements or
empty with component certificate (U-certificate) to be used as basis for further certification of
an Equipment or Protective System.

It is forbidden to change anything (components, installation, wiring ...) without the
prior written consent of Bartec Technor.
We cannot accept any responsibility for failure to observe these regulations:
• Make sure of the compatibility between the information on the nameplate, the
explosive atmosphere present, the area of use and ambient temperatures on surfaces
• Any damage on the device can cause the explosion-proof protection to become
ineffective
• The installation of the enclosure must be done in the state of the art in the technical
domains and only by qualified, competent and empowered personnel
• A defective or abnormal use as well as the non compliance with the instructions of the
present document exclude any clause of guarantee and do not engage our
responsibility
• The use of the device in case of excessive deposits of dusts superior at 50mm
according to EN / IEC 60079-31 is not authorized
• Liability for manufacturer traceability is ensured only at the first known delivery
destination (serial number specified on the certification label)
• It is also required to observe the regulations of the country of use
• The doors of the DE8-BC enclosures are relatively heavy, to avoid sagging of the
doors, potentially making the door not align with the flange of the enclosure, the doors
shall be closed and secured during any moving and shfting of the enclosures. It is
also strongly advisable to close and secure the doors when the daily working shift is
over
• The flame paths of the doors and of the flanges of the enclosures must be well
protected whilst work is performed and ongoing inside the enclosures
Transport, storage
• Check it the product has been damaged during transport. If any damage is observed,
do the statutory reserves to the carrier
• Do not put damaged products into service

external substances) and closed with temperature a
constant humidity (-40°C < T < +70°C). Shielded from
important temperature variations
2 years and more with regular inspection (cleanliness
and mechanical damage)
Putting into service
• Verify that the information on the label of the product is in accordance with the
permissible conditions for the Ex area of the site of use (Group II: Surface Industries Category 2: high level of protection for ATEX G = for Gas / D = for Dust, IECEx EPL G = for Gas / D = for Dusts - IPxx: IP rating (waterproofness for solids and liquids)
• Check if there is a specific position of mounting
• The wiring of the cable conductors must be made with a particular care
• The conductor insulation must reach the terminal. The conductive soul must not be
damaged
• Not to exceed the authorized maximal temperature appropriate cables must be
selected and take particular care installing them
• Follow the instructions contained in the specifications
• Installation of intrinsic safety elements :
o The installation of the intrinsic safety circuits (IS) inside the enclosure is
subordinated to the respect of the requirements of their documents of
certification, their certificates and with that after:
IS Circuits are cabled with connection wires of which the thickness of
insulator is ≥ 0,5 mm and the section ≥0,5 mm ²
The connection wires support a dielectric test of 500 V effective
The air gap between the active parts under voltage of the connection
elements of the intrinsic safety circuit compared to connection
elements of an non intrinsic safety circuit is higher or equal to 50
millimeters
The air gap and creepage distances in the air between the active parts
under voltage of the intrinsic safety circuit compared to an intrinsic
safety circuit close are higher or equal to 6 millimeters
The air gap and creepage distances in the air between the active parts
under voltage of the intrinsic safety circuit compared to the metal parts
which can be with the ground are higher or equal to 3 millimeters
The active parts of the intrinsic safety circuits support a dielectric test of
rigidity under an effective alternating voltage of 500 Volts compared to
the metal mass
The active parts of an intrinsic safety circuit support a dielectric test of
rigidity under an effective alternating voltage of 500 Volts compared to
an intrinsic safety circuit close
Circuits NIS are cabled with conductive wires whose insulation is such
as they can support a dielectric test of 2 U + 1000 V effective, U being
the sum of the tensions of the IS and NIS circuits, with a minimum of
1500 V
Before starting
• Make sure the unit has been correctly settled and not damaged
• Make sure the wiring and the tightening of the terminal screws have been performed
properly (see descriptive tightening torque)
• The device may include any foreign body and no part is damaged
• The cable gland must be tightened (see description of the gland torque)

Maintenance
The maintenance and repairs works on devices must be made only by authorized and
trained persons for that purpose.
Before any work the devices must be switched off. In addition:
• Prevent and avoid any formation of layers of dusts: make a periodic cleaning with a
wet cloth
• Do not take apart the command and control units (push buttons, pilot light, etc.)
It is adviseable that the following checks must be made at least once a year:
• The external equipment and surfaces must not be damaged
• The cable entries and blanking plugs must be securely fastened
• Check tightness of the connections, rewiring if necessary
• Prior to closing, check the cleanliness of the flame path (machined part of the cover in
contact the machined part of the box). Grease these 2 parts with a grease resistant to
oxidation (acid free white vaseline)
•
Screw the cover on the box using the original stainless steel bolts A4-70 minimum.
Ensure that all the bolts are screwed. After tightening the bolts, check with a shim of
15/100 mm (4/100mm for IIB + H2) all around the flame path that the shim cannot
penetrate the enclosure. Its non-penetration on full perimeter is the insurance of the
conformity of the product with the standards

Special Conditions for safe use (X):
When the enclosure is equipped with intrinsic safety elements, a temperature probe must be
fitted inside and be connected to a system that can switch off the supply when the inner
temperature raises above the maximum ambient temperature indicated in the certificates of
the IS equipment.
The products that can be connected to the IS equipment installed inside the enclosure must
be of a certified type and association must be compatible in regards of intrinsic safety.
