BEKA BA688CF-F, Manual, Page: 6 / 15

4. INSTALLATION
4.1 Location
The BA688CF-F FOUNDATION™ fieldbus display
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 4 shows the overall dimensions of the
BA688CF-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.
The BA688CF-F liquid crystal display has
maximum contrast when viewed from directly
ahead and slightly below the centre line of the
instrument.

4.2 Installation Procedure
a. Insert the BA688CF-F into the instrument
panel cut-out from the front of the panel.
b. Fix panel mounting clips to opposite sides of
the instrument and tighten. Recommended
tightening torque is 22cNm (1.95lbf in).
Do
not over tighten . Four clips are required to
achieve an IP66 seal between the
instrument enclosure and the panel.
c. Connect the panel wiring to the rear
terminal block(s) as shown in Fig 5. To
simplify installation, the terminals are
removable so that panel wiring can be
completed before the instrument is installed.
