9. 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).
Specific conditions of use
● Parts of the enclosure may be non-conducting and may generate an ignition-capable
level of electrostatic charge under certain extreme conditions. The user should ensure
that the equipment is not installed in a location where it may be subjected to external
conditions (such as high-pressure steam), which might cause a build-up of electrostatic
charge on non-conducting surfaces.
● Aluminium, magnesium, titanium or zirconium may be used at the accessible surface of
the equipment. In the event of rare incidents, ignition sources due to impact and friction
sparks could occur. This shall be considered when the Sitrans LR200 is being installed in
locations that specifically require Equipment Protection Level Ga
● The end user must ensure that the explosion protection and ingress protection is
maintained at each entry to the enclosure by use of an appropriate blanking element or
cable entry device that meets the requirements of the protection concepts type 'n' or
increased safety 'e' or flameproof 'd'.
