6.2 IQ Panel Cutout Retrofit
It is possible to retrofit the outer chassis to an existing IQ style
panel cutout if the panel is guaranteed to be .125 inches thick and
distortion free. Insure that there are no mechanical problems that
could effect the overall mounting thickness of the outer chassis from
the termination back to the front of the latching frame.
Given an acceptable, undistorted IQ cutout then the outer chassis
must be disassembled to put the latching frame on the front and the
outer chassis box on the back of the panel. The six mounting nuts
on the plastic mounting frame should be removed, saved for
reassembly, and the frame pulled from the outer chassis assembly.
The back plate frame is removed leaving the back metal chassis
box. This back plate is then not needed since the assembly panel is
replacing it.
From the back of the panel pass the chassis box studs through the
IQ panel cutout mounting holes, see
Figure 6-3
. From the front of
the panel apply the latching frame onto the studs and replace the
mounting nuts. Snug the nuts to get a hand free fit and inspect the
opening. The IQ panel cutout should not project beyond the inside
lip of the latching frame or it will hang up on the FP-5000 inner
chassis slide guides. Note that there is some slop in the outer
chassis mounting studs being size 8 and the panel holes being a
size 10. By adjusting the fit on the panel the clearance may be
removed or if necessary file the opening so that the inner chassis
passes without interference. The inner chassis should slide in/out
without binding and the face plate should lay evenly against the
latching frame with little gap ( ~ .030 inches max). When finished
follow the startup check out procedures outlined in Section 7 to
ensure that the draw-out termination is engaged adequately.
Figure 6-2. Panel Cutout and Mounting Holes
Before actually cutting the panel, check the required three-
dimensional clearances for the FP-5000 case, particularly behind
the panel. See dimensions in
Figure 6-1
and
Figure 6-2
. If
mounting on a swinging door, check the swinging clearance of rear
projections and wired connections.
Figure 6-2
shows dimensions for the panel cutout and mounting
holes. Cutout tolerances and mounting screw hole placement are
critical. In particular, the tolerance of the horizontal dimension
between the center of the mounting holes and the vertical edge of
the cutout must be between 0 and +0.050 in. (0.13 cm).
The Outer Chassis assembly is installed in the panel from the front,
user side with the four mounting studs passing through the four
panel mounting holes as shown in
Figure 6-2
. Secure the assembly
from the inside of the panel with the four number 10 mounting nuts
provided. Use moderate torque of ~ 10 inch pounds. The front
latching frame and backing plate should be snug against the mounting
panel. If it is not, inspect the installation for accuracy of the panel
cutout and possible interference, correcting as necessary.
