MC3820 and MC5720 Cameras Installation Instructions

CAUTIONS

CAUTION

In order to avoid damaging your camera, note the following points.

1) The camera has threaded mounting points on the top and bottom of the case. Only
use a standard, photographic mounting bolt with a 1/4-20 UNC thread.

2) Before fitting the lens, make sure that its back will not touch the CCD sensor or
associated components when fully installed.

3) Do not touch the image surface of the sensor. If the sensor is accidentally touched,
only clean it using isopropanol.

4) Do not expose the sensor to direct sunlight as this may impair the performance of
the camera.

POWER SUPPLY

The MC3820 and MC5720 Series cameras are available in 230 VAC or 11-40 VDC/14-30 VAC low
voltage types. The voltage required to operate the camera is clearly marked on the rear

panel of the camera. Power the low voltage cameras only from a class 2 isolated power
supply. The power consumption is less than 5 Watts.

230 VAC Power Supply

Cameras that are intended to operate directly from 230 VAC are fitted with a non-detachable power
supply cord. The voltage of operation is clearly marked on the rear panel of the camera. Generally
this is 230 VAC +10% /-15% at 50 Hz. Refer to the wiring instruction label attached to the supply
cord and terminate the cord with the appropriate circuit with a 3A fuse. CAMERAS MUST BE
CONNECTED TO A PROTECTIVE EARTH GROUND. Ensure that a secure means of isolation from
the AC power is provided for the camera in accordance with the national wiring regulations of the
country of installation.

Auto-switching power supply

Cameras fitted with an automatic selecting power supply operate between 11-40 VDC and 14-30
VAC. Connections and polarity are indicated above the screw terminals on the rear panel. The
power supply must be a class 2 isolated type.
