Safety notes

Process pressure
The device construction allows process over-pressure up to 10 or 25 bar (146 or 365 psi). This
pressure is allowed for test purposes. The definition of the Ex approvals are only valid for a
container-over-pressure between -0.2 to +0.1 bar (-2.9 to +1.45 psi). For higher or lower
pressures, approvals are not valid.
Process and ambient temperature
Please check the ambiment and process temperatures at Flame Proof and Dust Ignition Proof
(CLS200) (Page 71) for the specific configuration you are about to use or install.
Chemical resistance against the medium
If the equipment is likely to come into contact with aggressive substances, then it is the
responsibility of the user to take suitable precautions that prevent it from being adversely
affected, thus ensuring that the type of protection is not compromised. Aggressive
substances: e.g. acidic liquids or gases that may attack metals, or solvents that may affect
polymeric materials. Suitable precautions: e.g. establishing from the material's data sheet
that it is resistant to specific chemicals.
Cable entry devices / blanking elements
• Dust Ignition proof. For use in potentially explosive dust atmospheres: The cable entry
devices and the blanking elements of unused apertures shall be of a certified type,
suitable for the conditions of use and correctly installed. The minimum ingress protection
requirement of IP6X according to EN 60529 must be satisfied.
• Flameproof. For use with potentially explosive gas atmospheres: the cable entry devices
and the blanking elements of unused apertures shall be of a certified flameproof type,
suitable for the conditions of use and correctly installed.
• Versions with cable gland mounted by default. The used cable gland is only suitable for
fixed installations. The installer is responsible for providing appropriate strain-relief to
prevent pulling or twisting.
• Versions with blanking element mounted by default. Blanking elements are not to be
used with any form of adaptors or reducers.
