Rear O-ring
Rear plate mounting screws

Tube of Loctite® 222 low-strength thread locker
A service kit is included in case you need these spare parts in the future. Save this kit.
NOTE: If installing a heater or blower, do it first. Refer to C1495M-A (accessories manual) for instructions on installing heaters
and blowers.
1. Attach the cradle to a mount or pan and tilt unit. Follow the instructions supplied with the mount or pan and tilt unit.
2. Remove the enclosure’s rear plate with the supplied 5 mm Allen wrench.
3. Remove the camera sled from the rail in the body by removing the Allen screw in the end of the sled. Use the supplied
3/16-inch Allen wrench.
4. If the camera lens is adjustable, extend the lens to its maximum length.
5. Position the camera over the appropriate mounting holes on the sled and fasten the camera to the sled with the two
provided 1/4-20 x 1/2-inch screws. Make sure the lens does not extend beyond the front edge of the sled. This ensures
the lens does not contact the enclosure window after installation.
NOTE: You will need to use elevation blocks (EB1 or EB2) to properly elevate cameras with either a low optical center line
or a large-diameter lens.
6. Replace the camera sled in the enclosure, but do not reinstall the 1/4-20 Allen screw that holds the sled in place.
7. Install the sealing fittings on the rear of the enclosure. If you only need one fitting for wiring, install the supplied pipe
plug in place of one of the fittings.
8. Bring the wiring through the fitting(s) for camera video and power and, if applicable, power for the accessories (heater
and/or blower). Refer to Table A for 24 VAC applications only (accessories and camera).
9. Attach the video cable to the camera. Connect power to the camera and, if applicable, to the accessories.
10. Attach a ground wire to the 10-32 x 3/8-inch screw on the inside of the rear plate.
GROUND
IMPORTANT NOTE: The internal grounding terminal must be used for the equipment
grounding connection and the external terminal is for a supplementary bonding connection
where local codes or authorities permit or require such connection.
SCREW
Figure 1.
Grounding Location
11. Push the camera sled all the way into the enclosure and fasten the sled with the 1/4-20 Allen screw.
12. Leave the desiccant bag inside the enclosure to absorb moisture. Replace the rear plate. Apply Loctite to the screws.
Loctite 222 low-strength thread locker prevents corrosion between the stainless steel screws and aluminum enclosure
parts. Corrosion causes the parts to seize, resulting in damage to them during disassembly.

13. If required, attach a ground wire to the terminal lug on the rear plate.
IMPORTANT NOTE: The internal grounding terminal must be used for the equipment grounding connection and the external
terminal is for a supplementary bonding connection where local codes or authorities permit or require such connection.
14. Connect the video and power wiring from the sealing fittings to their sources through fittings and conduit suitable for
hazardous locations.
15. For U.S. and Canada Only – Seal the fittings as specified by the manufacturer’s installation instructions in manual
C903M-A. Sealant is not supplied or available from Pelco.
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 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.

OPERATION
If your enclosure has a heater, the heater turns on at 40°F (4°C) and turns off at 60°F (16°C).
If your enclosure has a blower, the fan operates continuously.
MAINTENANCE
REGULAR MAINTENANCE
WARNING: Do not remove the front cover. If you do, Pelco cannot be held responsible for the loss of explosionproof
rating, UL listing, or ability of enclosure to contain an explosion.
Regularly scheduled maintenance will help to prolong the operational life and appearance of the equipment.
1. Periodically look inside the window of the enclosure and check the humidity indicator on the roof. Lavender indicates
normal at the desired level of humidity. Pink indicates excessive dampness and blue indicates dryness. For example, if
you want to maintain a humidity level of 20%, the 20% dot should be lavender.
2. Clean the window regularly with a mild nonabrasive detergent in water to help maintain picture clarity. For a heavily
soiled window, use a glass cleaner.
3. Inspect the sealing fittings frequently for the condition of the sealant.
A service kit contain a rear O-ring and four rear plate mounting screws is included with the enclosure. Use these spare parts if
the original parts are damaged or lost during maintenance or repair of the enclosure.
SERVICE MANUAL
If you need to service the enclosure, obtain a service manual in one of the following ways:
•
