– Find the three cable clamps that are also used to mount the acrylic trim piece. There are
three sets of hardware. Install using the hardware provided. Orient the cable clamps as
shown in Figure 5.10. The proper order of hardware is as follows (from bottom of chassis
to top): screw head (6-32 x 3/8) / flat washer / cable clamp / chassis / lockwasher / standoff
/ chrome spacer / flat washer / screw head (6-32 x 3/4). The acrylic cover will be installed
later.
– Examine FL51, the AC line filter. Note there are two chassis mounting tabs. One tab also
serves as a standoff for the acrylic cover. Note also one end of the device is marked “line.”
This end should face the rear panel.
– Secure the rear-facing end of FL51 using the #6 hardware provided. Include a ground lug
between the mounting tab and the nut on the Line side. Note that the mounting tab may be
notched to permit easier assembly. With a notch in the mounting tab, the screw / ground
lug / nut can be started and then the device tab slid in place. Leave the nut finger-tight for
now.
– Install the front-facing hardware for filter FL51, which should be oriented as follows:
screw head (6-32 x 3/8) / flat washer / FL51 mounting tab / chassis / lockwasher / standoff
/ flat washer / screw head (6-32 x 3/4). The acrylic cover will be installed later. As with
Figure 5.9 Back panel with components installed.
