4. INSTALLATION
4.1 Location
The BA648CF-P 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
BA648CF-P 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.

4.2 Installation Procedure
a. Insert the BA648CF-P 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 until the
instrument is secure. 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 as shown in Fig 3. To simplify
installation, the terminals are removable so
that panel wiring can be completed before
the instrument is installed.

4.3 EMC
The BA648CF-P complies with the requirements of
the European EMC Directive 2004/108/EEC. For
specified immunity, all wiring should be in
screened twisted pairs with the screens earthed at
one point.
