Step 25:
Strip 1 /
2
" off the ends of the low voltage wire and attach ends to the transformer
terminals; red lead to RED, black lead to BLK.
A dab of household petroleum jelly on each terminal will help prevent
corrosion.
We recommend crimping a spade-tongue terminal (not provided) to the end of
each wire before attaching it to the transformer.
Make sure the exposed wires DO NOT touch each other!
Step 26:
Plug in the transformer.
We strongly recommend using a surge protector
with the transformer.
HINT: Keep a few mothballs in the control box to discourage insects from entering it and damaging the
control board.
Step 24:
Strip 3 / 16” off the ends of the low voltage wire and twist
each wire end tightly. Attach these ends to the 18VAC
terminals located on the POWER IN terminal block (see
illustration above). Make sure the exposed wires DO
NOT touch each other!
Insert one transformer wire in an 18VAC terminal.
Insert the other transformer wire into the remaining
18VAC terminal. The transformer wires can be
connected to the 18VAC terminals regardless of color.
Tighten set screws against exposed wires. A dab of
household petroleum jelly on each terminal will help
prevent corrosion.
