where the panel offers very little support. It is recommended that the 9 inch minimum center line di-
mension between horizontally mounted rows be increased as the number of units increases, or that
the panel strip be stiffened.
The rear of the instrument case must be supported to prevent panel distortion. Mount an angle iron
or similar member along the bottom of the cases as indicated in Figure 2-3. If the panel is to be
moved the instrument cases must be tied down to prevent damage.
If multiple mounted instruments are installed in a panel that tilts back, it may be necessary to sup-
port the instruments so the panel does not sag. The downward weight should be supported by addi-
tional panel supports and/or by increasing panel thickness.
2.3.2 MOUNTING PROCEDURE
For single and multiple case mounting the instruments are furnished with a trim collar (mounting
frame). Figure 2-3 illustrates the installation and use of the trim collar (mounting frame). Trim col-
lars (mounting frames) are available in various sizes and are supplied to conform with the particu-
lar panel cut-out.
NOTE
Mounting brackets and trim collars (mounting frames) are packaged
separately. Check the shipment carefully to prevent loss of mounting
hardware.
To install single or multiple mounted instruments in a prepared panel cut-out, proceed as follows.
1. Remove the through-case shipping bolt
2. Slip the trim collar (mounting frame) over the rear of the case and slide it forward to the
front of the case.
3. Slide the instrument case through the panel opening.
a) Single mounting case - support the weight of the case and attach the top and bottom
mounting brackets. Tighten the bracket screws.
b) Multiple mounted cases -
MicroMod
Automation spacer bars and self-adhesive pads must
be used between the cases, as shown in Figure 2-4. Start the installation from the right
(when facing the panel), installing the spacers as each case is added. As each case is posi-
tioned in place, install and tighten the top and bottom mounting brackets. Each case must
be tight against the previous case.
NOTE
Spacers are not required on the outside of the right and left cases.
