a. Loosen the screws.
b. Slide the sled so that the screws are in the large part of the mounting
holes.
c. Remove the sled.
d. Remove the parts tied to the sled.
3. EH4718-1, -2, -3 Models, and EH4722 -1, -2, -3 Models Only - If you are
installing the enclosure in a marine or high-moisture environment, make the
following modifications to your enclosure:
Refer to Figure 1 for an exploded assembly diagram of the blower assembly.
a. Remove the two sets of screws and washers (A, B, and C) that secure
the fan shroud (3) to the bottom of the enclosure.
b. Remove the four screws (D) that secure the fan (4) to the back of the
enclosure.

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.
EH4718 and EH4722 Models Only - Wire the camera’s lens control directly
to the lens controller.
EH4718-1, -2, -3 Models, and EH4722-1, -2, -3 Models Only - Refer to Figure 2 and wire the motorized zoom lens control as follows:

11. EH4718-1, -2, -3 Models, and EH4722 -1, -2, -3 Models Only - Refer to
Figure 2 and connect the camera’s power input to the circuit board.
There are two ways to supply power to the camera: when the power requirements for the camera and enclosure’s accessories are the same (for example,
if the camera and accessories use 24 VAC), and when the power requirements for the camera and the enclosure’s accessories are different (for example, if the camera uses 24 VAC and the accessories use 120 VAC).
When the power requirements are the same, there are two ways to connect
power:
(1) A three-pin plug is supplied as loose equipment. Connect the wires from
the plug to the camera as follows:
Brown - AC HI
Blue - AC NT
Green - Ground
Connect the plug to the CAM 1 socket on the circuit board (remove the
plastic cover over the power supply section of the circuit board).
or
(2) If both the camera end enclosure use 120 VAC and you ordered the
optional 120 VAC electrical outlet accessory (O/I-OUTLET), connect the
120 VAC plug to the camera and the three-pin plug to CAM 1 (remove
the plastic cover over the power supply section of the circuit board).
When the power requirements are different, connect the wires from the
two-pin plug, which is supplied as loose equipment, to the camera as
follows:
Brown - AC HI
Blue - AC NT
Connect the plug to the CAM 2 socket on the circuit board.
12. Wire power to the enclosure to operate the camera.
EH4718 and EH4722 Models Only - Wire power directly to the camera. If you
are using 24 VAC, refer to Table A to determine the size of wire to use.
EH4718-1, -2, -3 Models, and EH4722-1, -2, -3 Models Only -
CAM 1 - If the camera’s power input is connected to CAM 1 on the circuit
board, go to step 13.
CAM 2 - If the camera’s power input is connected to CAM 2 on the circuit
board, wire power for the camera as follows:
a. Connect AC high to connector 9 of the 10-connector INPUTS terminal
block (goes to the brown wire in the CAM 2 connector).
b. Connect AC neutral to connector 10 of the 10-connector INPUTS termi-
nal block (goes to the blue wire in the CAM 2 connector).
