Description
Our range of explosion proof enclosures is available in many sizes. They are machined and painted in steel or stainless steel
316L. Each is expected to receive electrical components inside, making it easy replacement or maintenance. They can also be
customized to meet each individual specific need. If necessary, multiple enclosures can be assembled on a frame with junction
boxes and / or switching coupled or separated.
Enclosures can be delivered fully equipped according to customer requirements or EMPTY with a partial certification (certificate
with U extension) to be used as basis for certification of an Equipment or Protective system.

 Decrees, orders, laws, directives, circulars, applications, standards, state of art and other documentation relating to its
installation site
It is forbidden to change anything (components, installation, wiring ...) without the prior consent of Bartec Technor.
Meaning of symbols
This symbol means a hazard or precaution to be taken
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 and surfaces.
Any damage of the device can have for consequence to make ineffective the explosion-proof protection.
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
Transport, storage

Check it the product has not been damaged during transport. If any, do the statutory reserves to the carrier

Do not put into service damaged products
Packaging
Open
Location storage
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
Duration storage
2 years and more with regular inspection (cleanness
and mechanical damage)

Putting into service

Verify that the information on the label of the product are 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
Dusts for IEC Ex GPL - 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, it is advisable to choose the appropriate cables and take a
particular care in installing them

Follow the instructions contained in the specifications

Installation of intrinsic safety elements:

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:

Circuits IS 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.)
The following checks must be made at least once a year:
 The outdoor equipment and surfaces must not be damaged

The cable entries and blanking plugs must be threaded

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 (OPAL - Siberia, for example)

Screw the cover on the box using the 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 flam 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 also be fitted inside and be
connected to a system that can switch off the supply when the inner temperature raises the maximum ambient
temperature indicated in the certificates of the IS elements.
The products that can be connected to the IS elements installed inside the enclosure must be certified type and
association must be compatible in regards of intrinsic safety.
The content of the DE8-BC enclosure may be placed in any arrangement provided that an area of at least .
- 20 % of each cross-sectional area remains free for groupIIB
- 40 % of each cross-sectional area remains free for group IIB + H2
