4. INSTALLATION
4.1 Location
The BA414DF-F Fieldbus Indicator 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 offshore and waste water treatment
installations. Please consult BEKA associates if
high vibration is anticipated.
The BA414DF-F enclosure is surface mounting.
Accessory kits described in sections 6.3 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 BA414DF-F earth terminal is connected to the
carbon loaded GRP enclosure. If this enclosure is
not bolted to an earthed post or structure, the earth
terminal should be connected to a local earth.
The BA414DF-F enclosure is supplied with a
bonding plate to ensure electrical continuity
between the three conduit / cable entries.
Note:
Although certified for safe use between
–40
and
+70
o
C,
the
guaranteed
operating
temperature range of the BA414DF-F Fieldbus
Indicator is –20 to +70
o
C.
4.2 Installation Procedure
Fig
2
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 6.3
c. Remove the temporary hole plug and install
a cable gland or conduit entry with required
ingress protection. If more than one entry is
required, replace one or both IP66 stopping
plugs with a cable gland or conduit entry
having the required ingress protection.
d. Connect the field wiring to the terminals as
shown in Fig 3.
e. Replace the instrument terminal cover and
evenly tighten the two 'A' screws.
CAUTION installation in Zone 0
When installed in a Zone 0 potentially
explosive
atmosphere
requiring
EPL
Ga
apparatus, the instrument shall be installed
such that even in the event of rare incidents, an
ignition source due to impact or friction
between the aluminium label and iron/steel is
excluded.
No special conditions apply when the indicator is
installed in Zone 1 or in Zone 2.

4.3 EMC
The BA414DF-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 earthed at
one point in the safe area.
