Plug in transformer to power outlet. (Use of a surge protector is
highly recommended. If outdoors use weatherproof box.)
Secure with terminal screws.
Feed other end of low voltage wire 10” into box through
the hole.
Insert one wire into each 18VAC terminal. Colors do not matter.
Cut excess cable/strip 1/2” off 2 wires/twist ends. Attach wires
to transformer screw terminals.
