WIRING — CHASSIS BOTTOM
Refer to Pictorial 6 (Illustration Booklet, Page 4) for
the following steps.
( \) Position the two green power transformer leads
through grommet P for connection later.
Connect the remaining power transformer leads as
follows:
ties to lug 2 of terminal strip S (S-1).
( a) Black-yellow to lug 3 of terminal strip S (NS).
( \Y Green-yellow to ground lug 8 of terminal stripS
(NS).
( caine blue to ground lug 8 of terminal strip S
ou
( Longer blue to lug 5 of terminal strip Q (NS).
( /Black to lug 4 of terminal strip Q (NS).
eee to lug 2 of terminal strip Q (NS).
(Yh Position the transformer leads as shown.
NOTE: Use the small solid hookup wire in all wiring
steps, unless directed otherwise. Cut the specified
color of wire to the length given in the step. Then strip
1/4” of insulation from each wire end, unless directed

( At the end of this wire with the most insulation
removed, pass the wire through lug 10 (S-2) to
lug 9 (S-1) of switch B. Connect the other end of
the wire to lug 2 of control C (S-1).

Connect the other end of the wire to lug 1 of
control C (S-1). Be sure the bare portion of the
wire does not touch any other lugs or the switch
assembly bolt.
ae Connect one end of a 9" gray wire to lug 6 of
switch B (S-1). Pass the other end through hole
H in the circuit board for connection later.

Connect one end of a 7” red wire to lug 12 of
switch B (S-1). Pass the other end through hole

switch B (S-1). Pass the other end through hole
H in the circuit board for connection later.

terminal strip N (NS). Pass the other end
through grommet P for connection later.
hee to the inset drawing on Pictorial 6 and
connect one end of a 10” large blue wire to the
diode lead (point A) extending from the circuit
board (S-1). Pass the other end through grom-
met F for connection later. Cut off the excess
diode lead.
( Oe tetas the cable assembly and position it on the
chassis as shown.
