c. Move the fan out of the way and remove the fan shroud.
d. Turn the fan around so that it blows toward the viewing window (refer to
the arrows on the fan).
e. Reinstall the fan on the back of the enclosure.
f. Close the enclosure lid.
g. On the bottom of the enclosure, remove the vent grills (1) and filter (2) at
the front and back of the enclosure. Replace the grills with the vent cover
plates that were attached to the camera sled as loose equipment.
h. Open the enclosure lid.
4. If you are going to wire the enclosure with cable, remove the wiring glands
and nuts from the parts bag and install them in the bottom of the enclosure. If
you are going to wire the enclosure with conduit, do not install the glands.
5. Mount the camera to the sled with the 1/4-20 Phillips-head screws that are
provided in the parts bag. You can mount the camera to either side of the sled.
Note that the edges of the sled are bent and that one lip is wide and the other
is narrow.
Normally you should mount the camera so that the wide lip of the sled fits over
the mounting screws.
If you are installing a camera with a low optical center line or a camera with a
large diameter lens, mount the camera so that the narrow lip of the sled fits
over the mounting screws. This elevates the sled.
6. There are two threaded mounting holes on the bottom of the enclosure. Mount
the enclosure to a pan/ tilt assembly or fixed mount with 1/4-20 screws with
threads that do not exceed 5/8 of an inch (1.59 cm) in length (not supplied with
the enclosure).
7. Install the sled and camera in the enclosure:
a. If the camera’s lens is adjustable, extend the lens to its maximum length.
b. Place the sled on the rail over the three attaching screws.
c. Slide the sled so that the screws fit into the narrow slots of the mounting
holes.
d. Tighten the screws just enough to hold the sled to the rail, but not too
tight to keep the sled from moving.
e. Slide the camera sled forward until the lens almost touches the window.
f. Tighten the three screws to secure the camera sled to the rail.
8. Wire the video output from the camera.
9. If you are going to synchronize cameras, wire the camera’s synchronization
connection.
10. If your camera has a motorized zoom lens control, wire it.
