IOM Single Case BiRotor Plus R06
Essential Instructions for Equipments To Be Used In Hazardous Locations Including the European
Union (Directive 2014/34/EU)
Any Hazardous area approval applies to equipment without
cable glands. When mounting the fl ameproof enclosure in
a hazardous area only cable glands / conduit seals certifi ed
to meet or exceed the rating of the equipment should be
used, refer to the type approval documentation for further
details. It is the end users responsibility to ensure this
happens.
Cable glands and cable must be suitable for the operating
temperature of the device under its rated conditions, this is
especially important is the device has an operating
temperature above 1580F (700C).
The meter has been provided with an approved sealing
device in one of the cable entries, the other entry has been
closed with a plastic cap plug. It is the end users
responsibility to remove the cap plug and replace it with a
suitable cable gland or conduit seal before the equipment
is put into service.
It is the end users responsibility to ensure when the
instrument is located in a hazardous area that all cable
glands and conduit seals must be installed in accordance
with the local codes and regulations.
It is the end users responsibility to ensure that before
opening an electronic enclosure in a fl ammable
atmosphere; all the electrical circuits must be interrupted.
If replacement of the screws which secure the sensor
housing, the UMB cover of the electronic register and its
cover are required, they must be replaced with either
factory direct parts or M6-1 x 16 (6g) mm hex socket head
screws of equal length. The screws must be made from
stainless steel grade A1-70 or A2-70 and be torqued to a
value of 55 in lbs upon installation, its is the end users
responsibility to ensure this happens.
It is the end users responsibility to assess the maximum
surface temperature of the device and the equipment
the device is attached to and located next to as this may
exceed the temperature ratings of the device itself. If this
happens, additional safety precautions will need to be
implemented by the end user.
Flame proof housings contain Aluminium; although the
composition of these enclosures is carefully maintained
to prevent any risk of an ignition source it is the end users
responsibility to ensure that the housing is not struck by
rusty tools or objects.
If the equipment is to be installed in an area where dust
deposits and build up are to be expected, a maintenance
plan should be arranged to include regular removal of the
dust build up. This will prevent the dusts forming a possible
source of ignition.
The power supply requirements for this product are
specifi ed with in the operating and maintenance manual, it
is the end users responsibility to operate the product with
in these specifi ed limits.
The instrument contains surfaces that constitute fl ames
paths, these surfaces should not contain any mars or
scratches, if any are present the factory or the local
representative should be contacted immediately to
obtain a new housing as the safety of the enclosure may be
impaired. It is the end users responsibility to inspect these
surfaces every time the enclosure is opened.
When fl anged fl ame paths are reassembled the gap
between them should be less than 0.0015” (0.038 mm)
such that a +/- ”(12.5mm) wide feeler 0.0015” (0.038mm)
gauge will not enter the gap more than 1/8” (3mm). It is the
end users responsibility to ensure this happens each time
the enclosure is reassembled.
