Instructions for the FP-6000 Protective Relay
Before actually cutting the panel, check the required three-
dimensional clearances for the FP-6000 case, particularly behind
the panel. See dimensions in Figures 27 and 28. If mounting on a
swinging door, check the swinging clearance of rear projections
and wired connections.
Figure 28 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. (1.27mm).
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 28. Secure the
assembly from the inside of the panel with the four number 10
mounting nuts provided. Use moderate torque of ~ 10 inch
pounds (1.13 N
•
m). 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.

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 0.125 in. (3.18 mm)
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 29. 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-6000 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 in.[0.76 mm] max). When finished follow the startup
check out procedures outlined in Section 7 to ensure that the
drawout termination is engaged adequately.
