ENCLOSURE POWER

If the enclosure does not have a heater (model HS4514), proceed to the Camera Mounting section.

If your enclosure has a heater (models HS4514-1/-2), follow the steps below.

1.Add the camera wattage to the wattage of the heater. Refer to the Specifications section, for the heater wattage.

2.Determine the size of wire to use. If you are using 24 VAC, refer to Table A.

3.Bring wires for AC high, AC neutral, and ground into the enclosure. Refer to Figure 1 and Figure 2, and connect the wiring as follows:

a.Connect AC high to AC HI of the 3-connector terminal block.

b.Connect AC neutral to AC NT of the 3-connector terminal block.

c.Connect ground to GND of the 3-connector terminal block.

Table A. 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 AC-powered devices.)

EXAMPLE: An enclosure that requires 30 VA and is installed 94 feet (28 m) from the transformer would require a minimum wire gauge of 20 AWG.

NOTE: Distances are calculated in feet; values in parentheses are meters.
