Mounting
Attach the enclosure to the appropriate mount or pan/tilt; refer to the instructions supplied with
the equipment. Mount the EH3010 or EH3014 enclosure with the provided 1/4-20 bolts, flat
washers, and split lock washers.

Table B. 24 VAC Wiring Distances
The following are the recommended maximum distances for 24 VAC applications and are calcu-
lated with a 10-percent voltage drop. (Ten percent is generally the maximum allowable voltage
drop for AC-powered devices.)

Total vA consumed
EXAMPLE:
An enclosure that
requires 80 vA and is installed
35 feet (10 m) from the trans-
former would require a minimum
wire gauge of 20 Awg.
NOTE:
Distances are calculated
in feet; values in parentheses are
meters.
