Special conditions for safe use (denoted by X after the certificate number)
● 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 LR250
mA/HART is being installed in locations that specifically require group II, level of protection Ga or Da.
● The equipment shall be bonded to the system earth in accordance with the relevant code of practice.
● When the SITRANS LR250 mA/HART is used in the presence of combustible dust, the gland that is fitted to the equipment
shall also be suitable for use in the presence of combustible dust, as certified by an ATEX notified body, in addition, the
installation of the gland shall not compromise the IP6X rating of the equipment enclosure.
