8.5 Preparing the mounting surface — surface
mounting
Surface mounting requires one cutout hole. When the performance display is
surface mounted, the glass/bezel will protrude from the mounting surface.
Note:
The following procedure is for preparing the mounting surface for surface
mount installations. For flush or retrofit / offset mounting details, refer to:
• p.32 — Preparing the mounting surface — flush mounting
• p.33 — Preparing the mounting surface — retrofit / offset mounting
Important:
Before preparing the mounting surface ensure that:
• Your selected location meets the location requirements. For details refer
to: p.22 — Location requirements
• You have identified cable connections and the route that the cables
will take.
1. Mark the cutout line identified on the supplied mounting template on
the mounting surface.
2. Use a drill and an appropriate size drill bit or hole cutter to cut out the
corners of the cutout line. The corner diameter for the instruments is
8.00 mm (0.31 in).
3. Use a jigsaw or similar cutting tool to cut out the remainder of the cutout
area.
4. Use a half round file and/or sandpaper to smooth and rough edges or
burs on the cutout hole.
8.6 Preparing the mounting surface — flush
mounting
Flush mounting requires the same cutout hole as surface mounting and an
additional rebate around the edge of the cutout area. When the performance
display is flush mounted, the glass will be flush with the mounting surface.
Note:
The following procedure is for preparing the mounting surface for flush
mount installations. For surface or retrofit / offset mounting details, refer to:
• p.32 — Preparing the mounting surface — surface mounting
• p.33 — Preparing the mounting surface — retrofit / offset mounting
Important:
Before preparing the mounting surface ensure that:
• Your selected location meets the location requirements. For details refer
to: p.22 — Location requirements
• You have identified cable connections and the route that the cables
will take.
