( ) At the other end of this twisted pair, connect
the black wire to lug 2 (NS) of terminal strip
Y.
( ) Connect the brown wire to lug 1 of the

NOTE: A flat 3-lead line cord is supplied with
this kit that is approved for use in the U.S.A.
and
in some other countries. If this cord is not
approved for your locality, obtain locally an
approved cord and proceed with the following
steps, making changes where necessary.
The flat 3-lead line cord supplied with this kit has
one of its outer leads marked with ribs in the
insulation along its edge. The other lead is
smooth, and the third lead is color coded green.
( ) Separate the three line cord leads for a
distance of about 1-1/2" from the stripped

amount of solder to the sm all wires at the
end of each lead. This will hold the sepa-
rate strands together.
( ) Pass the line cord through the hole in the
rear panel.
( ) Connect the green line cord lead to the
solder lug of Y (S-1).
Connect the ribbed line cord lead to lug 4
of
the power transformer (NS).
Connect the smooth line cord lead to lug 1
of
terminal strip Y (NS).
Connect one lead of the fuse to lug 1 of
terminal strip Y (S-2).
( ) Connect
the other fuse lead to lug 2 of ter-
minal strip Y (S-2).

given below: one for 120 VAC line voltage, and
the other for 240 V AC line voltage on Page 34.
In
the U.S.A., 120 VAC is most commonly used,
while in some other countries 240 VAC is more
