.4 Either violet wire to fan B1 lug 1 (S-1). Make a
mechanically secure connection.
4 Remaining violet wire to fan Bl lug 2 (S-1).
Make a mechanically secure connection.
Connect the free end of the blue solid wire com-
ing from rear panel socket J3 to relay K1 lug 10
(S-1).
Connect the free end of the braided wire com-
ing from relay K1 lug 7 to coaxial socket J2 lug 1
(S-1).
( Connect the free end of the braided wire com-
ing from relay K1 lug 9 to coaxial socket J1 lug 1
(S-1).
A Connect the free end of either medium black
stranded wire coming through the cutout at the
bottom of the center panel to the eyelet of
terminal strip CB lug 3 (S-1).
(Y Connect the free end of the remaining medium
black stranded wire coming through the cutout
at the bottom of the center panel to the eyelet
of terminal strip CB lug 4 (S-1).
NOTE: Refer to inset drawing #1 on the Pictorial for
the relay lug numbering when you connect wires to
them in the following steps.
1Y Prepare a 7" yellow solid wire. Then connect
the wire from relay K1 lug 8 (S-1) to diode D3
lug 2 GS-1).
Ww Ri: Cut both leads of a 47 kQ, 1/2-watt (yel-
viol-org) resistor to 1/2”. Then connect the wire
from diode D3 lug 1 (NS) to terminal strip CB
lug 2 G-1).
(Y Remove all of the insulation from a 1-1/4"
length of black solid wire. Then connect the
wire from diode D3 lug 1 (S-2) to terminal strip
CBlug 1 (NS).
/ Route the free end of the long brown solid wire
coming from the meter circuit board as shown.
Then connect the end of the wire to relay K1 lug
461).
4 Prepare a 24” blue solid wire. Then connect one
ancness 2
Heathkif
end of the wire to relay K1 lug 11 (G1). Route
the free end of the wire as shown and out
through the indicated hole in the front
subpanel. This end of the wire will be connected
later.
Route the free end of the shorter (unconnected) small
coaxial cable, coming from the input filter assem-
bly, as shown. Then connect the wires at the end of
the cable as follows:
A Inner wire to relay K1 lug 6 (NS).
Y Shield wires to the upper solder lug at CA
(NS).
Route the free end of the large coaxial cable coming
from switch SW2D as shown. Then connect the wires
at the end of the cable as follows:
/
4) Inner wire to relay K1 lug 2 (NS).
Shield wires to the upper solder lug at CA
(S-2).
ue Refer to Detail 6-14B and use 6-32 x 3/8" hard-
ware and a cable clamp to secure the three
cables to the center panel at CR.
Refer to Pictorial 6-15 while you perform the
following steps.
Ww Route the free ends of the longer red and gray
wires coming from the meter circuit board as
shown.
Position the ALC/power circuit board near the ends
of the red and gray wires. Then connect the wires to
the circuit board as follows:
aw Red wire to hole D (S-1).
(WY Gray wire to hole E (S-1).
Y Refer to Detail 6-15A and use 6-32 x 5/8"
hardware and a 5/16" spacer to mount the
ALC/power circuit board to the center panel as
shown. Be sure to position the circuit board as
shown in the Pictorial before you tighten the
hardware.
