➍ On the vertical terminal strip, connect the green forked
wire to the terminal labeled GND.
NOTE: The green ground wire MUST be connected
properly to provide electrical surge protection.
➎ Snap open the protective cover and connect one of the
remaining two forked wires to one of the terminals labeled
24VAC. (In some units, these two terminals are labeled
ORN.) Connect the last forked wire to the other terminal
labeled 24VAC. Polarity of these two wires is not impor-
tant. You may connect either wire to either terminal. Then
close the protective cover.
➏ Verify that all connections are secure. Then plug the
transformer into any standard three-prong grounded
117VAC electrical outlet.
CAUTION: To prevent electric shock, match the wide
blade of the plug to the wide slot, fully inserted.
