2. WIRE CHART
PLEASE NOTE: If the wires you are pulling for this installation are going to be run through an indoor,
weather-proof location, it is acceptable to use unshielded cable. If the wires are going to be run through
an outdoor location, we recommend that you use shielded cable. Recommendations for both types of
cable are provided where needed.

PLEASE NOTE: If you are using the larger sizes of cable (i.e., 12 awg or 10 awg), you may experience
problems inserting the wires into the terminal block. If you encounter this problem, you can connect a
16-18 awg wire (with the use of a wire nut) to each end of the power cable, as long as the smaller gage
wire is under 12 inches in length.
