Use only 12 to 18 AWG (2.5 – 1.0 mm
no more than 0.25 inch (6 mm) of wire insulation from the ends of the power leads. If
stranded wire is used, be sure that there are no loose strands outside the connector
plug that could touch the adjacent lead and cause a short circuit.
a.
24V AC/DC models.
For 24VDC operation, connect the positive lead to the (+) terminal and
the negative lead to the (-) terminal of the connector plug as shown in figure 2.
For 24VAC operation connect the line (hot) power source wire to the
terminal marked "L". Connect the common (neutral) power source wire to the terminal
marked "N". See figure 2. If required by local building codes, connect the earth ground
wire to the green screw threaded into the interior of the enclosure.
