Conditions for Safe Use (ATEX)
• Under rated conditions, the branching point at the entry point may reach 80°C, therefore, when choosing
cables and cable glands this shall be taken into account.
• When removing the conduit plug to fit the data transfer socket to the communication adaptor and during
data transfer, the user/installer shall ensure that no explosive atmosphere is present. After data transfer has
finished, the conduit plug shall be re-fitted in accordance with the relevant Code of Practice.
• When the standoff tube is fitted, it shall be used with turbine meter pick off coil bosses in accordance to
those listed in certificate Sira 03ATEX1474U.
• The product may be fitted with a communication adaptor. When removing the conduit plug to fit the data
transfer socket to the communication adaptor and during data transfer, the user/installer shall ensure that
no explosive atmosphere is present. After data transfer has finished, the conduit plug shall be re-fitted in
accordance with the relevant Code of Practice.
• Some external parts of products that have aluminium housing are non-conducting and may generate an
ignition-capable level of electrostatic charges 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 charges on nonconducting surfaces.
Additionally, cleaning of the equipment should be done with a damp cloth.
• An ATEX-approved standoff tube shall be used with a Barton 7000 Series turbine pickup coil boss or a
NuFlo turbine pickup coil boss in accordance with certificate SIRA 03ATEX1474U. See the
MC-III Parts
List (ATEX), page 98
, for part numbers.
• Replace the lithium battery only with the ATEX-approved battery supplied by Cameron (Part No. 9A-
90099000).
• The lithium battery that powers the MC-III EXP is a sealed unit; however, should a lithium battery
develop a leak, toxic fumes could escape upon opening the enclosure. Ensure that the instrument is in a
well-ventilated area before opening the enclosure to avoid breathing fumes trapped inside the enclosure.
Exercise caution in handling and disposing of spent or damaged batteries.
