Our service oering
In addition to standard enclosures, we also provide you
with customization of standard enclosures and creation of
special-design enclosures. We also oer customer-specic
integration services as a part of our enclosing solutions. These
integrations can be made for all of our enclosures, and the
deliverey is a ready, functioning package for the customer’s
own assembly process.

Ensto recognizes this by taking all due caution to minimize therisk of ignition caused by materials or by the
design of an enclosure.The structure must be designed to eliminate all electro-static charges. Generally
charges are formed when two materials with different charges come into contact with each other. A larger
contact area or greater distance between the surfaces of the materials touching each other increasesthe
likelihood of acharge. Danger
of an increasing charge in material increases when the resistivity of the other
material decreases.
If the material has a charge, an electro-static discharge may occur. A charge can be discharged in many ways,
but the most common ways are spark discharges and brush discharges. Both of these can cause a dangerous
ignition, because the energy released can ignite gases and vapors. A spark discharge occurs when the charge
between two conductors in different potentials increases to a sufficient level. In a brush discharge, energy is
released when a charged object is approached by a round conductive object.
Thes
e charges can be eliminated effectively by using potential equalisation or grounding. Potential
equalisation refers to the connection of two conductive objects to eachother. Grounding refers to the
connection of a conductive object to the ground potential. Discharging must be used when the protective
structure is used in a space where explosion group IIC gases are present and the thickness of a non-conductive
surface layer exceeds 0.2 mm or the surface resistivity exceeds 1 GΩ. In equipment class two it must be
ensured that the projection surface area of non-conductive components, such as value plates and sticker
s, does
not exceed 20 cm
2
. If the non-conductive surface is surrounded by an grounded frame, its surface area can be
multiplied by four.
2.2.Explosion groups
The specification contains three explosion groups. These groups are based on the measured ignition
capabilities of gases and vapors at a certain temperature. The classification is split into sections I and II, and
groups designated A, B, and C. For example, group A contains common alcohols with a low flash temperature
and group C contains gaseous hydrogen with a relatively high flash temperature. (Tukes, pages 8-10)
The table below shows examples of the ign
ition temperatures of gases and vapors in different temperature
classes and explosion subdivisions(Tukes, pp. 11-33).

CuboLink Lite conguration tool
CuboLink Lite is an Internet-based conguration tool designed
for customizing our enclosures. The tool provides excellent
support for the electronic order-delivery process making the
process leaner and faster.
This tool is simple to use. You can select the standard enclo-
sure from our range and then easily perform the necessary
conguration. Openings and components can be added by
using the drag-and-drop functionality.
