Wall Mounting (Slimline Cabinet)
(front-service use)
– see Figure 2(a)
Mark a horizontal line on the wall 27mm below
the intended top of the cabinet.
Mark a vertical line from the first line where the
centre of the cabinet will be.
Hold the mounting bracket against the wall with
its top edge against the horizontal line and its
central hole over the vertical line. Mark the
location of the mounting screws.
Fasten the mounting bracket to the wall but do
not completely tighten the screws.
Hang the cabinet on the mounting bracket and
then tighten the screws.
Drill a hole at the base of the cabinet and put a
screw through it to lock the cabinet in position.
Window Mounting Slimline Cabinet
(rear-service use)
The
MX1
Slimline cabinet can be mounted in a
window frame for rear-service use in New Zealand.
To do this, mounting holes must be drilled where
necessary in the side and top or bottom of the
cabinet. The mounting bracket cannot be used.
Note that the cabinet door opens within the vertical
profile of the cabinet body, so the cabinet can be
mounted flush in a cavity if required.
Wall Mounting (15U Cabinet)
The 15U cabinet is supplied pre-drilled with four
keyholes suitable for mounting screws of not more
than 8mm shaft diameter and 11mm head
diameter. A drilling template is supplied with each
unit. Refer Figure 2(b). The keyhole detail is shown
in Figure 2(c).
EXTERNAL WIRING
Cable Entry
Slimline Cabinet
There are five 20mm knockouts provided in the top
and five knockouts in the bottom of the cabinet.
Refer Figure 3(a). Other entry holes can be drilled
as required.
To prevent water entering the cabinet, seal unused
knockouts and any top cable entries. Where
possible, use bottom cable entry with cables going
down 100 mm below the cabinet before rising.
15U Cabinet
The 15U cabinet has 2 x 50mm and 5 x 20mm
knockouts in the top and 2 x 50mm and 4 x 20mm
knockouts in the bottom. Refer Figure 3(b).

plate. Unplug the 10-way loom from the keyboard and
unclip the loom from the front panel before removing the
gear plate.
Clean out all swarf from the cabinet before replacing the
