a. Loosen the screws.
b. Slide the sled so that the screws are in the large part of the mounting
slots.
c. Remove the sled.
d. Remove the parts tied to the sled.
3. TC9346A-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. Disconnect the electrical plug (3) from the fan (4).
b. Remove the three sets of screws and washers (A, B , and C) that secure

c. Remove the four screws and washers (B and D) that secure the fan to
the fan plate.
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 fan plate.
f. Reinstall the fan plate and fan in the enclosure.
g. Reconnect the electrical plug on the fan.
h. Close the enclosure lid.
i. On the bottom of the enclosure, remove the vent grill (1) and filters (2) at
the front of the unit. Replace the grill with one of the v ent cov ers that was
attached to the camera sled as loose equipment.
j. On the bottom of the enclosure, attach the other vent plate over the grill
at the rear of the unit.
k. Open the enclosure lid.
4. If you are going to wire the enclosure with cable, remov e 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/lens 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
U-shaped sled, depending on the camera height required.
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/lens in the enclosure:
a. If the camera’s lens is adjustab le, extend the lens to its maxim um length.
b. Place the sled over the mounting screws in the enclosure.
c. Slide the sled forward until the camera’s lens almost touches the window .
d. Tighten the screws to secure the camera sled to the enclosure.
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.
TC9346A Model Only – Wire the camera’s lens control directly to the lens
controller.
TC9346A-1, -2, -3 Models Only
Refer to Figure 2 and wire the motorized zoom lens control as follows:
a. Connect or wire the lens control from the camera to the LENS or LENS
CONTROL connector on the circuit board.
6
Page 7
b. Wire the 10-connector INPUTS terminal on the circuit board to the lens
controller as follows:
• Lens Common - Connector 1
• Focus - Connector 2
• Zoom - Connector 3
• Iris - Connector 4
• Preset Common - Connector 5
• Preset Focus - Connector 6
• Preset Zoom - Connector 7
• Preset High - Connector 8
11. TC9346A-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 camer a - when the po wer requirements for the camera and enclosure’ s accessories are the same (for e xample,
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).
WARNING:
damage possible.
Camera
You
can damage your camera
if you connect it to the
wrong connector.
If your camera will use the same
power as the enclosure, plug the
camera into the CAM 1 socket on
the circuit board.
If your camera’ s voltage will be different from the enclosure’ s voltage,
plug the camera into the CAM 2
socket.
DO NOT
plug the camera
into the CAM 1 socket or you can
damage your camera. CAM 1 has
enclosure voltage on it.
BE CAREFUL - REMEMBER
CAM 1 IS ENCLOSURE
POWER
NEVER PLUG YOUR CAM-
ERA INTO CAM 1 IF THE
CAMERA’S VOLTAGE IS
DIFFERENT FROM THE
ENCLOSURE’S VOLTAGE.
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 and enclosure use 120 VAC and you ordered the op-
tional 120 VAC electrical outlet accessory (O/I-OUTLET), connect the
120 V A C plug to the camera and the three-pin plug to CAM 1 (remov e the
plastic cover over the power supply section of the circuit board).
When the power requirements are different, connect the wires from the twopin 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.
TC9346A Model 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.
TC9346A-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).
7
Page 8
13. TC9346A-1, -2, -3 Models Only
Wire power to the enclosure to operate accessories (and the camera if its
power is connected to CAM 1 on the circuit board) as follows:
a. Remove the plastic cover over the power supply section of the circuit
board.
b. Connect AC high to AC HI of the 3-connector terminal block.
c. Connect AC neutral to AC NT of the 3-connector terminal block.
d. Connect ground to GND of the 3-connector terminal block.
e. Reinstall the plastic cover over the power supply section of the circuit
board.
If the camera’s power is connected to CAM 1 on the circuit board, add the
camera’s wattage to the power consumption of the accessories to determine
the size of wire to use. If you are using 24 VAC, refer to Table A to determine
the size of wire to use. Here are the wattages for the accessories:
Defrosters for all enclosures - 30 watts
Wipers for all enclosures - 15 watts
Blowers for 120 VAC enclosures - 15 watts
Blowers for 24 VAC enclosures - 10 watts
Blowers for 230 VAC enclosures - 15 watts
Heaters for 120 VAC enclosures - 90 watts
Heaters for 24 VAC enclosures - 50 watts
Heaters for 230 VAC enclosures - 70 watts
14. Adjust the camera focus and iris, if necessary.
15. Close the enclosure lid.

T ab le A. 24 V AC 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 80 vA and is installed 35 feet
(10 m) from the transformer would
require a minimum wire gauge of
20 AWG.
NOTE:
Distances are calculated in
feet; values in parentheses are
meters.

4.0 OPERATION
If your enclosure has a thermostatically controlled blower, the thermostat is set to
turn the fan on between 77° and 93°F (25° and 34°C) and to turn the fan off between 62° and 78°F (17° and 26°C).
If your enclosure has thermostatically controlled heaters or defroster, the thermostat is set to turn them on between 42° and 58°F (6° and 14°C) and to turn them off
between 72° and 88°F (22° and 31°C).

5.0 MAINTENANCE AND TROUBLESHOOTING
5.1 MAINTENANCE
Perform the following maintenance at regularly scheduled intervals to prolong the
operational life and appearance of the equipment.
1. Clean the window with a mild non-abrasive detergent in water and a soft cloth
to maintain picture clarity.
2. If your enclosure has a blower, clean the foam filters as follows:
a. On the bottom front of the enclosure, remove the two screws in the vent
grill.
b. Remove the vent grill and tak e out the filters .
c. Clean the filters with warm water and mild detergent, dry thoroughly, and
replace them in the grill.
d. Reinstall the vent grill.
To order replacement filters, use the part number EH550010045.
5.2 TROUBLESHOOTING
If your enclosure has the optional circuit board (O/I-PCB) and you need to troubleshoot it, Figures 3 through 5 show the wiring, component locations, and layout of
