For Explosion Proof installations, the internal ground connection shall be used. The external ground connection, is an
additional wiring allowed where local authorities permit, or is required. Use a ground wire of proper cross section.

Both internal and external grounding connections are clearly identified and permanently marked on the box housing and are
projected to facilitate the installation of the ground cable preventing it from rotating.
3.16
A grounding connection kit composed by n°2 phillips head screws plus n°2 toothed washers, is provided in a sealed bag,
available inside the box. The two anti-vibration washers help to ensure the securing of the cable.

WARNING!:
Risk of electrostatic charges accumulation on non-conductive parts of the box (eg. Plastic indicator dome).
The external surfaces of the box
must be preserved by the accumulation of dust through periodic cleaning.
Clean Only with a
Damp Cloth.

CAUTION!:
The box can work in plants in presence of extreme environments and in contact with highly aggressive and
corrosive substances that may affect the integrity of the product and its protection mode. To operate in such conditions the
box is projected to be realized in different materials that ensure durability and reliability in operation. For the right choice of the
available options, please contact Eisenbau.
