The segment can provide an additional 13mA
to power the Fieldbus Indicator.
The equivalent capacitance Ci of the
BA414DF-F Fieldbus Indicator is zero and
the equivalent inductance is insignificant.
Therefore these BA414DF-F parameters do
not need to be considered.
A1.3 Certification Label Information
The certification label is fitted in a recess on the
top outer surface of the enclosure. It shows details
of the ATEX dust certification including the
maximum
surface
temperature
and
ingress
protection; a statement that the instrument is a
FISCO Field Device, plus BEKA associates name
and location. IECEx dust approval information is
also shown, non-European certification information
may also be included.
The label includes boxed areas which should be
marked by the installer to show which of the
certifications is being used.
The instrument serial number and date of
manufacture are recorded on a separate label
inside the terminal compartment.
A1.4 Installation & maintenance
The ATEX dust certification relies on the Fieldbus
Indicator enclosure being dust-tight.
Therefore
the terminal cover should only be removed when
dust cannot enter the instrument enclosure. Before
replacing the terminal cover ensure that the
sealing gaskets are undamaged and are free from
foreign bodies.
