IMPORTANT SAFEGUARDS AND WARNINGS

Prior to installation and use of this product, the following WARNINGS should be observed.

1. Installation and servicing should only be done by qualified service personnel and con­form to all local codes.

2. Unless the unit is specifically marked as a NEMA Type 3, 3R, 3S, 4, 4X ,6 or 6P enclo­sure, it is designed for indoor use only and it must not be installed where exposed to
rain and moisture.

3. Only use replacement parts recommended by Pelco.

4. After replacement/repair of this unit’s electrical components, conduct a resistance
measurement between line and exposed parts to verify the exposed parts have not
been connected to line circuitry.

5. The installation method and materials should be capable to supporting four times the
weight of the enclosure, pan/tilt, camera and lens combination.

The product and/or manual may bear the following marks:

This symbol indicates that dangerous voltage
constituting a risk of electric shock is present
within this unit.

This symbol indicates that there are impor­tant operating and maintenance instructions
in the literature accompanying this unit.

DESCRIPTION

The EH3508/EH3512/EH3515 Series are indoor/outdoor light-duty camera enclosures de­signed for use with various cameras on the market and accommodate fixed focal length or
motorized zoom lenses, with or without auto-iris operation.

The lid of the enclosure is hinged in the front providing easy access during installation and
when camera and lens adjustments are necessary. The camera sled also serves as an el­evation block. Y ou can remove, flip, and then reinstall the sled to elevate the camera. All wir­ing and cabling is brought into the enclosure through adjustable glands at the bottom rear
of the enclosure.

The rear link-lock latch can be used with a padlock of suitable size for applications requiring
additional security.

INSTALLATION

The following items are supplied to mount the enclosure:

2 1/4-20 x .500-inch hex head screws
2 Flat washers
2 Split washers

The following items are supplied to mount the camera:

2 1/4-20 x .375-inch Phillips-head screws

and blower, 22 watts.
13 watts.

and blower, 27 watts.

and blower, 32 watts.
23 watts.

Perform the following steps to install the enclosure, camera, and lens:

1. Unlatch and open the lid.

2. Remove the camera sled from the rail.
a. Loosen the screws that hold the camera sled in place.
b. Slide the sled forward so it can be lifted out over the screws.
c. Remove the sled.
d. Remove the parts tied to the sled.

3. If you are wiring the enclosure with cable, remove the glands and nuts from the parts
bag and install them in the bottom of the enclosure. If you are wiring the enclosure
with conduit, do not install the glands.

4. Attach the enclosure body to the appropriate mount using the instructions provided
with the mount.

Attach the enclosure through the threaded mounting holes in the bottom of the enclo­sure. Use the 1/4-20 x .500 screws and washers provided (in the parts bag). Com­pletely tighten the screws to attach the enclosure body to the mounting surface.

5. Attach the camera to the sled with the 1/4-20 x .375-inch Phillips-head screws pro­vided (in the parts bag). You can attach the camera to either side of the sled. The side
of the sled to which you mount the camera depends on the type of camera and lens
you are attaching.

The edges of the sled are bent–one side up and the other side down. On one side of
the sled, the lip is wide; on the other side of the sled, the lip is narrow. In a typical in­stallation, you mount the camera so that the holes in the wide lip of the sled fit over the
sled mounting screws.

However, you can elevate the sled if you are installing a camera with a low optical cen­ter line or a camera with a large diameter lens. To elevate the sled (and therefore el­evate the camera), flip the sled over so that the holes in the narrow lip of the sled fit
over the sled mounting screws.

6. Move the sled so that the sled mounting screws extend through the narrow part of sled
mounting holes, and partially tighten the sled mounting screws.

Pelco Manual C478M-L (11/03) 3

7. Pull the video and power cables through the glands or conduit on the bottom of the en­closure. Refer to Tables A and B to determine the size of power wire to use. Refer to
Table C for the type of video coaxial cable to use.

8. Attach the cables to the camera.

9. If the enclosure has accessories that require power, connect the power to pins 1 and 2
on the PC Board (refer to Figures 1, 2, and 3 for information about accessory wiring).
Connect ground to pin 3 if required.

You can connect the camera power to the PC board if the voltages are the same be­tween the accessories and camera. If you want to connect the camera power to the PC
board, connect the camera power to pins 1 and 2. Connect ground to pin 3 if required.

10. If the camera lens is adjustable, extend the lens to its maximum length; verify that the
camera is adjusted with the lens a minimum of 1/2 inch from the enclosure window.

11. Tighten the screws that secure the sled to the enclosure.

12. Adjust the glands for a tight fit around the cables.

13. Close the enclosure lid, and latch.

14. Adjust the camera focus and iris if necessary. If you need to adjust the focus and iris
manually, open the enclosure lid, adjust the focus and iris, and close the enclosure lid.

OPERATION

If your enclosure has a thermostatically controlled heater, the thermostat is set to turn on at
50°F (10°C) and to turn off at 80°F (27°C).

If your enclosure has a blower and/or defroster, they operate continuously.

MAINTENANCE

Regularly scheduled maintenance prolongs the operational life and appearance of the
equipment. Clean the window regularly with a soft cloth using a mild, nonabrasive detergent
and water to maintain picture clarity.
