5.4 Instructions specific to hazardous area installations
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'.
