Route
the
green
and
green-yellow
wires

Connect one end
ol
a
3'1
14" yellow
hookup
wire to
lug 5
of
the
terminal strip
(S-3). The
other end
of this
wire
will
be
connected later.
DetailSN
Refer
to
Detail 8N and
form
a
twisted
pair
from two
12"
lengths
of green
hookup
wire.
Remove
114"
of
insulation
from the
end
of
each
wire.
At
one end
of the
twisted pair.
connect one
of
the
green
wires
to
lug 1
(NS) and the other green wire
to
lug
2
(S-4) of the terminal
striP.
Prepare
two
22"
green wires and
form
a
twisted
pair.
At
one end
of
the twisted
pair, connect one
wire to
lug
1
(S-3) and the
other
wire
to
lug
4
(S-4)
of
the
terminal strip.
Remove
the 6-32 hardware
from the terminal strip
and
transformer.
Refer
to
Detail 8P
and
cut
off
the
solder lug portion
of the mounting
foot
on
the
6-lug
terminal strip.
