5. Mounting the Base Unit
The 8900 may be mounted in a panel, on a wall, or on virtually
any surface including shelves, racks and pipes. All methods of
mounting the 8900 make use of the Signet Quick-clip for holding
the instrument securely in place. This unique clip eliminates the
hassle of locating and drilling holes for mounting screws.
If the 8900 will be mounted in a panel, plug-in modules may be
installed either before or after the base unit is mounted. If an
accessory Wall Mount Bracket will be used, fi rst install plug-in
modules.
5.1 Panel Mounting
•
The 8900 enclosure conforms to the ¼-DIN standard, which
requires a panel opening of 92 mm x 92 mm (3.6 in. x 3.6 in.).
•
¼-DIN punches are available and recommended for creating
clean, precise openings quickly and easily in most instrument
panels.
•
Alternatively, a jigsaw or other cutting tool may be used.
An adhesive template is provided to help guide the cutting
process.
•
Recommended minimum clearance on all sides between
instruments and panel edges is 25 mm (1 in.) as illustrated.
•
Use an appropriate fi le as necessary to shape and size the
opening, and to remove burrs.
