3-17. Remove the Front Panel Assembly
Remove all leads connected to the input terminals. Then remove the front panel 100 mA
fuse. Using needle nose pliers, disconnect the wires at the rear of the
X, [COM],
and [10 A] input terminals. At the rear of the [100 mA] terminal, carefully dislodge and
withdraw the spring (attached to the white wire) from the fuse holder.
Locate the display ribbon cable connector on the Main PCA ("A" in Figure 3-5.) Using
needle nose pliers, disconnect this cable by alternately pulling up on each end of its
connector. Avoid breaking the alignment tabs on the Main PCA half of this connection.
Now remove the Front Panel Assembly by releasing the four snap retainers ("B" in
Figure 3-5) securing it to the chassis.
3-18. Remove the Display PCA
The Display PCA is held in place with a set of tabs around its periphery. In sequence,
release the tabs along the top, left side, and right side. Then slide the pca up and out,
away from the bottom tabs.
Note
The Display PCA provides a space for a center securing screw. If the
peripheral tabs are intact, this screw is not necessary. If some of the tabs
are broken, the screw can be used as an additional securing device.
The elastomeric Keypad Assembly ("C" on Figure 3-5) can now be lifted away from the
Front Panel Assembly.
Remove the display window ("D" on Figure 3-5) by releasing the two snaps along its
inside, bottom edge. Use a gentle levering action between each snap and an adjacent
edge on the Display Assembly.
