Series 3 Cameras Installation Instructions
CAUTIONS
In order to avoid damaging the 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 BSW (20 UNC) thread.
2) Before fitting the lens make sure that its back will not touch the CCD sensor or
associated components when screwed fully home.
3) Do not touch the image-surface of the sensor. If the sensor is accidentally touched,
only clean it using ethyl alcohol.
4) Do not expose the sensor to direct sunlight as this may impair the performance of
the camera.
5) The weight of your camera is 0.5kg. (0.35kg. for VP.....2 versions)
6) Only use your camera in a clean, dust-free environment.
7) For outdoor use, an appropriate protective housing conforming to IP65 or UL50
or better must be used.
POWER SUPPLY
Cameras are available in AC mains and AC and DC low voltage types. The voltage required
to operate the camera is clearly marked on the rear panel of the camera. Only power
low voltage cameras from a class 2 isolated power supply. The power consumption of
a series 3 camera is less than 5 Watts.
Mains power supply
Cameras that are intended to operate directly from the mains supply 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 98 to 260 VAC at 50 Hz for CCIR/PAL (110 VAC ±10% at
60 Hzfor EIA/NTSC). REFER TO THE WIRING INSTRUCTION LABEL ATTACHED TO
THE SUPPLY CORD and terminate the cord with the appropriate mains plug fitted with a
3A fuse. MAINS CAMERAS MUST BE CONNECTED TO A PROTECTIVE EARTH
GROUND. Ensure that a secure means of isolation from the mains 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.
