Connect
24
VAC
power
to
the
large,
two
position
power
input
terminal
labeled
“POWER”
on
the
upper
right
hand
side
of
the
main
circuit
board
(Figure

Since
the
output
signals
are
isolated
from
the
power
supply,
it
is
not
necessary
to
provide
an
isolated
(secondary
not
grounded)
power
source.
Multiple
GTC116
transmitters
wired
to
a
single
transformer
must
be
wired
“in
‐
phase”
(L1
to
L1,
L2
to
L2).
