The 'X' suffix to the certificate number relates to the following special conditions for
safe use:
a. 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 influences which might cause a build-up of electrostatic
charge on non-conducting surfaces.
b. As either Aluminum, 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 LR 250 is being installed in locations that specifically require
group II, category 1G equipment.
