Description of the component
Our DE8-BC range of flameproof 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 are delivered with Ex Component certificate (U-certificate) to be used
as basis for further certification of an Ex Equipment or Protective System.
Meaning of symbols
This symbol means a hazard and precaution to be taken
Safety instructions
The device must be installed, used and maintained in accordance with the following
standards:
•IEC/EN 60079-0 (Explosive atmospheres - Part 0:
Equipment - General
requirements )
•IEC/EN 60079-1 (Explosive atmospheres - Part 1: Equipment protection by
flameproof enclosures "d")
•IEC/EN 60079-14 (Explosive atmospheres - Part 14: Electrical installations design,
selection and erection)
•IEC/EN 60079-17 (Explosive atmospheres - Part 17: Electrical installations inspection
and maintenance)
•IEC/EN 60079-31 (Explosive atmospheres - Part 31: Equipment dust ignition
protection by enclosure "t")
•Decrees, orders, laws, directives, circulars, applications, standards, state of art and
other documentation relating to its installation site
It is forbidden to change anything without the prior written consent of Bartec
Technor unless the enclosure undergoes a full Equipment certification at a Notified
Body/Certification Body.
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 flameproof 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
Packaging
Location storage
Duration storage
Open In a covered location, clean (without contact with
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)
Before starting
•Make sure the unit has been correctly settled and not damaged
•The device may include any foreign body and no part is damaged
•The cable gland(s) 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 entry devices and blanking plugs must be securely fastened
•Prior to closing, check the cleanliness of the flame path (machined part of the cover in
contact with the machined part of the box). Grease these 2 parts with a thin layer of
grease resistant to oxidation (acid free white Vaseline or Gleitmo 165).
Check the gasket for any damage. Replace if damaged. Grease the gasket using acid
free Vaseline.
• Screw the cover on the box using the original bolts as listed in the table below.
Ensure that the bolts are clean and are greased (grease like Gleitmo 165). Ensure
that all the bolts are fitted. Torque all bolts to the correct torque as listed in the table

yieldstress higher or equal to 700N/mm
2
and according to the tables above for the Lid bolts.
In accordance with D.3.10 of EN/IEC 60079-1, the content of the Ex component enclosure
equipment may be placed in any arrangement provided that an area of at least 20% (IIB) or
40% (IIB+H2) of each cross-sectional area remains free.
The length of flameproof joints are detailed in the drawing DE8BC-147-4.
The other conditions are stipulated in the instructions.
The content of the DE8-BC enclosures may be placed in any arrangement provided
that an area of at least:
•- 20 % of each cross-sectional area remains free for gas group IIB
•- 40 % of each cross-sectional area remains free for gas group IIB + H2
Dismantling, taking out of service :
When removing the enclosure and taking it out of
service, the same precautions apply as those observed
when mounting the enclosure.
