EXAMPLE: An enclosure that re- quires 80 vA and is installed 35 feet (10 m) from the transformer would require a minimum wire gauge of 20 Awg.
NOTE: Distances are calculated in feet; values in parentheses are meters.
3.6 POWER
There is no on/off switch. The CX9000 is “hot” when the fuse is installed and the input wiring is connected.
Refer to Table E for the recommended maximum distances when wiring 24 VAC applications. Refer to Figure 7 for AC input configurations and recommended fuse values.
Proceed to Section 4.0, OPERATION
Table E. 24 VAC Wiring Distances
The following are the recommended maximum distances for 24 VAC applications and are calculated with a 10 percent voltage drop. (Ten percent is generally the maximum allowable voltage drop for
