5. INSTALLATION
5.1 Location
The BA484DF-F FOUNDATION™ fieldbus display
is housed in a robust IP66 glass reinforced
polyester
(GRP)
enclosure
incorporating
an
armoured glass window and stainless steel fittings.
It is suitable for exterior mounting in most industrial
environments, including off-shore and waste water
treatment installations.
Please consult BEKA
associates if high vibration is anticipated.
The BA484DF-F enclosure is surface mounting.
Accessory kits described in sections 8.2 of this
manual enable the instrument to be mounted onto
a vertical or horizontal pipe.
The field terminals and the two mounting holes are
located in a separate compartment with a sealed
cover allowing the instrument to be installed
without exposing the display assembly.
The BA484DF-F earth terminal is connected to the
carbon loaded GRP case. If the case is not bolted
to a post or structure connected to the plant’s
potential equalising network, the instrument’s earth
terminal should be connected to the potential
equalising
network
as
recommended
in
EN 60079-14.
The BA484DF-F enclosure is supplied with a
bonding plate to ensure electrical continuity
between the three conduit / cable entries.
5.2 Installation Procedure
Fig
5
illustrates
the
instrument
installation
procedure.
a. Remove the instrument terminal cover by
unscrewing the two captive 'A' screws.
b. Mount the instrument on a flat surface and
secure with two M6 screws through the 'B'
holes. Alternatively use one of the mounting
kits described in section 8.2
c. Remove the temporary hole plug and install
an appropriate IP rated cable gland or
conduit fitting.
If more than one entry is
required, one or both of the IP66 stopping
plugs may be replaced with an appropriate IP
rated cable gland or conduit fitting.
d. Connect the field wiring to the terminals as
shown in Fig 6.
e. Replace the instrument terminal cover and
evenly tighten the two 'A' screws.

5.3 EMC
The BA484DF-F complies with the requirements of
the European EMC Directive 2014/30/EU.
For
specified immunity, all wiring should be in
screened twisted pairs with the screens connected
to
the
potential
equalising
network
as
recommended in IEC 60079-14.
