AC Power Wiring
The AC power wire size must be 20 to 10 AWG with the wire stripped 1/2 inch (14 mm). The wire insulation temperature must meet or exceed 85°C (185°F). Connect 100 to 240 VAC (25 watts maximum) to the Hot and Neutral terminals on the terminal block. Connect the ground wire to the safety ground lug. Torque all connections to 4.43 to 5.31 in- lbs (0.5 to 0.6 Nm). Use a separate conduit entry for signal lines to re- duce the possibility of AC noise interference.
