QO
Refer to Detail 6-7D and use 4-40 x 3/8" hardware
and a #4 solder lug to mount a vernier drive to the
subpanel at SH. Then tighten the hardware only
finger tight.
Refer to Detail 6-7E and use 4-40 x 3/8” hard-ware
to mount a vernier drive to the subpanel at SJ.
Tighten this hardware only finger tight.
Turn the shaft of the rotary switch on the meter
circuit board fullly counterclockwise. Then
remove the hardware from the switch bushing.
Now refer to Detail 6-7F and reinstall the detent
ring soits tabisin slot #4. NOTE: Besure the detent
ring tab stays in this position when you perform
the next step.
Refer to Detail 6-7G and use the following proce-
dure to mount the meter circuit board to the
subpanel at SK;
1. Dress the wires coming from the circuit
board as shown.
2. — Start the shaft of the rotary switch through
subpane! hole SK. Make sure the locating tab
on the switch enters its corresponding hole
in the subpanel. Also make sure there areno
wires pinched between the rotary switchand
the subpanel. Then use the large control nut
and large control lockwasher you removed
from the rotary switch in the previous step to
mount the circuit board to the subpanel.
Position the input filter assembly on the subpanel
as shown in the Pictorial. Then refer to Detail 6-7H
and use four 6-32 x 1/4" screws to secure the
assembly to the subpanel.
Thiscompletes the assembly of the frontsubpanel. Set it
aside until it is called for in a step.

MAIN CHASSIS
Refer to Pictorial 6-8 while you perform the following
steps.
&
(Cs
Y
Position the main chassis as shown in the Pictorial
(note the locations of the four larger holes where
the power transformer will be mounted later).
Refer to Detail 6-8A and use 6-32 x 1/2" hardware
and a #6 steel! flat washer to mount a foot on the
bottom of the main chassis at BA. NOTE: The flat
washer is a tight fit on the screw; you may have to
thread the washcr onto the screw.
Similarly mount feet onto the bottom of the main
chassis at BB, BC, and BD.
Refer to Pictorial 6-8B and use 6-32 x 1/4" hard-
ware to mounta 3-lug terminal strip onto the main
chassis at BE. Be sure to position the terminal strip
as shown in the Pictorial before you tighten the
hardware.
Similarly use 6-32 x 1/4" hardware to mount a 4-
lug terminal strip onto the main chassis at BF.
Position the terminal strip as shown in the
Pictorial.
Refer to Detail 6-8C and use 6-32 x 1-1/4" hard-
ware to mount a #6 solder lug onto the main
chassis at BG. Be sure to position the solder lug as
shown in the Pictorial before you tighten the
hardware.
Similarly use 6-32 x 1-1/4" hardware to mount #6
solder lugs onto the main chassis at BH and BJ.
Position each solder lug as shown in the Pictorial.
Similarly mount 6-32 x 1-1/4" hardware onto the
mainchassisat BK. Usea #6 lockwasher in place of
a solder lug.
