GENERAL 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.
DESCRIPTION Environmental enclosures in the EH4700 Series are used with pan/tilt units or fixed mounts. The enclosures are constructed of aluminum. You can install cameras with either fixed focal length lenses or motorized zoom lenses (up to 10X). All models have an adjustable camera sled to accommodate different sizes of cameras and lenses. MODELS EH4718 Environmental enclosure with rear opening lid. Lid has gas spring to hold it open. 18-inch (45.72 cm) length.
INSTALLATION 1. Unlatch and raise the enclosure lid. The gas spring will hold the lid in place when it is fully opened. 2. Remove the camera sled from the rail: 3. 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.
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.

EH4700 Series Input Wiring Diagram Pelco Manual C1405M-E (11/03) 7 2* CAMERA POWER INPUT TO CAM * CAMERA POWER (SUPPLIED WITH PCB) * CONNECT CAM 2 TO CAMERA WHEN THE CAMERA'S POWER IS DIFFERENT FROM THE AC POWER UNIT. * CONNECT CAM 1 TO CAMERA WHEN CAMERA'S POWER IS THE SAME AS THE AC POWER INPUT.
b. Wire the 10-connector INPUTS terminal on the circuit board to the lens controller as follows: • • • • • • • • WARNING: Camera damage possible. 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 inside the enclosure. If your camera’s voltage will be different from the enclosure’s voltage, plug the camera into the CAM 2 socket only.
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.) Wire Gauge EXAMPLE: An enclosure that re- quires 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 Total vA consumed feet; values in parentheses are meters.
13. EH4718-1, -2, -3 Models, and EH4722-1, -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.
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).
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 nonabrasive detergent in water and a soft cloth to maintain picture clarity. 2. If your enclosure has a blower, clean the foam filter as follows: a. On the bottom front of the enclosure, remove the two screws in the vent grill. b. Remove the vent grill and take out the filter. c.
