Power Connections

The 24VAC power lines enter the AD1273 through a 7-pin

Plug and Ramp connector (see Figure 9). The 7-pin Ramp

connector is mounted to the printed circuit board. The 7-pin

Plug mating connector is shipped with the AD1273 unit.

Assemble the 7-pin Plug connector by inserting the appropriate

24VAC power and ground lines into the corresponding slots

listed in Table 5 and tightening the hold-down screws.

Wire Selection

Table 6 lists the wire gauge versus maximum distance allowed

between the AD1273 pan/tilt and the voltage source. Shielded

cable is recommended for most applications.

Note: Distance calculations are based on solid copper wire,

single common, and worst case current draw (i.e.,

diagonal pan/tilt operation).
