strongly recommended - not included) If electrical
outlet is located outdoors, outlet and transformer
should be protected by a weatherproof cover.
Step 4
At the AC outlet strip
1
/2" of insulation from
the ends of the low voltage wire. Attach these
stripped ends to the transformer terminals.
A dab of household petroleum jelly on each
terminal will help prevent corrosion.
We suggest 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!
