Installation
Adequate ventilation extends the trouble-free life
of electronic instruments. It is generally found that
each 10° centigrade (18° F) rise in temperature re-
duces the life of electrical insulation by one half.
Adequate ventilation is an inexpensive and effective
means of preventing insulation breakdown that re-
sults from unnecessarily high operating tempera-
tures. The direct benefit of adequate ventilation is
longer, trouble-free life. Allow at least 15 inches
deep x 16½ inches wide x 3½ inches high for mount-
ing the MQ
101.
To prepare the MQ 101 for installation remove the
plastic protective covering. Turn it upside down so
that it rests on its top on the shipping pallet. Remove
the two screws that fasten the chassis to the cabinet.
After the screws have been removed slide the chassis
out of the cabinet. Next, place the mounting brackets,
the parts bag and the mounting template at hand.
The PANLOC professional mounting design elimi-
nates the need for any shelf or bracket. The MQ 101
is supported by its own mounting brackets.
The design of the mounting template allows you to
position or locate the cutout from the front or rear of
the panel to which the instrument is to be mounted.
Position the plastic mounting template over the area
of the mounting panel to be cut out for installation.
If the cutout is to be located from the front of the
panel, begin at Step 2. If the cutout is to be located
from the rear of the panel, begin here.
1. On the back of the mounting panel, scribe a ver-
tical centerline through the exact center of the
area in which the cutout is to be made.
Place the template against the back of the panel
and match the template centerline with the center-
line on the mounting panel.
Make sure that there is at least ¼ inch clearance
between the bottom of the dashed line of the cut-
out area on the template and any shelf or brace
below the proposed cutout.
Mark the locating holes ("C" holes on the
mounting template).
Drill the two locating holes. Be certain the drill
is perpendicular to the panel.
Now position the template on the front of the
panel by aligning the "C" locating holes on the
template with the drill holes.
2. If the cutout is to be located from the front of the
mounting panel:
With the template in place against the front of
the mounting panel, mark the "A" and "B" drill
holes and the four small holes that identify the
corners of the cutout. Join the corner marks with
a line. The edge of the template can be used as a
straight edge.
Accurately drill the holes on each side of the
cutout area with a
3
/
16
inch drill.
IMPORTANT: DRILL THE 6 HOLES BEFORE
MAKING THE CUTOUT
Carefully cut out the rectangular opening. Be cer-
tain to saw on the INSIDE of the lines.
Secure the mounting strips to the rear of the
mounting panel using two screws from the hardware
package. Insert the screws in the center holes of the
cabinet panel ("B" holes on the template) and
tighten. The screw head should pull into the wood
slightly. (Use two ¾ inch long screws for mounting
panels up to ½ inch thick, or two 1¼ inch long screws
for panels ½ inch thick and over.)
Attach the mounting brackets to the mounting
panel using four screws.
Place the template over the mounting screws. The
mounting screws should be centered in the "A" and
"B" holes on the template. The sides of the mount-
ing brackets should match the vertical dash lines on
the template. If necessary, loosen the screws and
push the brackets into alignment and retighten.
Insert the power cord through the mounting panel
opening. Carefully slide the MQ 101 into the opening
so the rails on the bottom of the equipment slide in
the track of the mounting brackets. Slide the instru-
ment in until its front panel is against the mounting
panel. At the bottom front corners are the PANLOC
buttons. Depressing the PANLOC buttons will lock
the instrument firmly in the installation. Depressing
the PANLOC buttons a second time (as with a ball-
point pen) will release the instrument. You can then
slide the instrument forward for easy removal.
