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)
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)
