4. INSTALLATION
4.1 Location
The BA418CF-F is housed in a robust aluminium
enclosure with a toughened glass window mounted
in a Noryl bezel. The front of the instrument
provides IP66 protection and a gasket seals the
joint between the instrument enclosure and the
panel. The instrument may be installed in any
panel providing the environmental limits shown in
the specification are not exceeded.
Fig 2 shows the overall dimensions of the
BA418CF-F and the panel cut-out. To achieve an
IP66 seal between the instrument enclosure and
the panel, the smaller cut-out must be used and
the instrument secured with four panel mounting
clips.
CAUTION
Installation in Zone 0
When installed in a Zone 0 potentially
explosive atmosphere requiring apparatus
of Category 1G, the indicator shall be
installed such that even in the event of rare
incidents, an ignition source due to impact
or friction between the aluminium enclosure
at the rear of the instrument mounting panel
and iron/steel is excluded.
The BA418CF-F liquid crystal display has
maximum contrast when viewed from directly
ahead and slightly below the centre line of the
instrument.
