CAMERA AND LENS INSTALLATION

To install the camera and lens, perform the following steps:

1. Use the supplied 5/64-inch hex wrench and loosen the screws located on the back of the enclosure.

2. Pull on the "T" handle and slide the camera sled out of the enclosure.

3. Mount the camera and lens onto the camera sled by doing the following:

a. Extend the lens to the maximum length before positioning the camera and lens.

b. Position the camera and lens so that they do not extend beyond the track.

c. Attach the camera and lens to the camera sled with the supplied fender washer, and one 1/4-20 x .375-inch Phillips pan head screw

and washer.

NOTE:

To prevent the entrance of dust or water, proper cabling must be used when wiring the enclosure. Use of ﬂat cable or multiple cables will

prevent the proper seal of the liquidtight gland connectors. Outdoor-rated sheathing should cover multiple cables. It is especially important that

you seal an unused gland connector.

To make all power and camera connections, follow the steps below:

1. If you have a heater, add the camera’s wattage to the wattage of the heater (the heater consumes 15 watts.) Maximum camera input

voltage must not exceed 240 VAC, and maximum camera power consumption must not exceed 10 watts.

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

3. Bring power wires for the heater and camera into the enclosure.

4. Connect the enclosure input power, camera input power, and video cable (refer to Figure 5 and Figure 6).

NOTES:

•The wiring diagram in Figure 5 (24 VAC) and Figure 6 (120/230 VAC) are for applications where the input voltage for the enclosure and cam-

era are different. For example, the enclosure input voltage is 120 VAC and the camera input voltage is 24 VAC.

• However, you may have an application where the input voltage for the enclosure and camera are the same. For example, the enclosure

input voltage is 120 VAC and the camera input voltage is 120 VAC. In applications where the input voltage for the enclosure and camera are

the same, wire the terminal block as follows:

(1) Connect the input power for the enclosure to terminal 3 (AC LINE) and terminal 4 (AC NEUTRAL).

(2) Connect a jumper wire from terminal 1 to 3 and a jumper wire from terminal 2 to 4.

5. Connect the ground wire for the enclosure power to the ground stud on the back of the enclosure. Refer to Tables A and B for information

on wiring size and distances.

6. Attach the wires from the camera to the two-pin camera power connector (provided). Connect the two camera power connectors together.

7. If the camera input voltage is 120 VAC/230 VAC, ground the camera to the ground stud located on the camera sled.

WARNING:

If you have a model with a heater, disconnect the heater wiring connectors before removing the camera sled from the

enclosure. Damage to the heater wires may occur if the sled is pulled out too far before the wiring connectors are separated.
