3.1 Installation of Camera and Lens

Carefully read the instruction manual before installation to learn whether the CCD
specifications and interface forms of the lens and camera are consistent; the 1/3 or 1/2 inch
lens can be installed in the 1/3 inch CCD camera, and only the 1/2 inch lens can be installed
in the 1/2 inch CCD camera, otherwise, vignette may be generated on the picture edge.

Figure 4. Lens Installation

After the lens and camera are installed, adjust the back focal length of the camera, and then
observe the clear degree of test card on the monitor.
Install the properly debugged lens and camera on the drawer plate of the housing, and adjust
their front and rear positions to ensure that the picture edge has no vignette after the barrel is
mounted.

3.3 Installation of Housing Barrel

The flameproof surface of the housing fits quite closely since the explosion-proof grade is
high. During installation, especially pay attention to protecting the flameproof surface; as
shown in the figure, the rear cover and the rear side of the barrel are flameproof surfaces,
which shall not be impacted or scratched during installation.

Figure 11. Careful Installation of Housing Rear Cover

An insulating spacer is provided between the drawer plate and the rear cover plate in the rear
cover assembly, and its insulation performance shall be paid attention to in case
disassembling is required; after assembling, measure its insulating resistance to ensure that it
is not less than 100MΩ. There is an externally grounded bolt in the center of the rear cover,
which shall be reliably connected to the earth when the equipment is installed.

3.6 Installation Precautions

SVEX-T500A Explosion Proof Camera User Manual.

 Check t

he following items before installing the product, and the product cannot be used if

it is non-conforming.
a. Whether there is explosion-proof certificate number;
b. Whether the explosion-proof mark applies to the environment of explosive gas

mixture;

c. Whether all explosion-proof parts are free from cracks and defects affecting the

explosion-proof performance.

 Correctly select the cable, ensure that the diameter of lead-in cable matches with the bore

diameter of rubber seal ring, select the minimum cable OD as per the mark on the end
face of the rubber seal ring, and guarantee that the gaps between the rubber seal ring and
the cable as well as the rubber seal ring and the lead-in device meet the explosion-proof
requirement after the hold-down nut is tightened.

 Set the nameplate and the warning sign “No Opening with Power” in an obvious position

on the surface of the product.

 During wiring, select the seal ring with inner bore of Φ10 and characters “≥Φ9.5” cast on

the end face, and select the cable of which the outer diameter matches with the internal
bore diameter of the seal ring, as shown in the figure.

≥Φ9.5

4-Description of Explosion-proof Structure

 Various special circumstances are adequately considered during structural design, so that

no explosion will occur in the environment full of explosive mixture outside the equipment
if sparks are generated in the equipment; moreover, the explosion-proof performance of
the equipment is guaranteed from the following aspects: enclosure strength, gap between
components, and highest surface temperature limitation of enclosure.

 The explosion-proof enclosure after finish machining must be able to withstand the

hydraulic test pressure specified in GB3836.2: 2.0MPa, not less than 10s, judged as
qualified in case of no water dripping and intact structure.

 The highest surface temperature of enclosure shall not exceed +80ºC during normal

operation.

 The lead-in device for the camera is fastened with the hold-down nut.
 The sight window of the camera is made of tempered glass, and thus can withstand the

impact and thermal shock tests.

SVEX-T500A Explosion Proof Camera User Manual.

Take the computar H2Z4516CS-2 lens which has three adjustable rings as an example:

“OPEN” and “CLOSE” are marked on the aperture ring, and the aperture ring can be directly

rotated to adjust the aperture; “OPEN” means increasing the aperture, and “CLOSE” means
decreasing the aperture. In the environment with weak light, increase the aperture to improve
the viewing effect; in the environment with ample light, properly decrease the aperture, so that
the screen will not turn white. In addition, increasing the aperture makes the depth of field get
smaller, and decreasing the aperture makes the same get larger.
A locking screw is set for the zoom ring and focusing ring respectively. Before adjustment,
rotate the screw anticlockwise, so that the zoom and focusing rings are in the adjustable state;
after adjustment, properly lock the screw.

“W” and “T” are marked on the zoom ring, and mean “WIDE” and “TELE”; adjusting towards
the “W” direction increases the view angle of the lens to the maximum, so “W” means wide

angle; adjusting towards the “T” direction decreases the view angle, and thus farther views can
be seen.
“∞” and “N” are marked on the focusing ring, and mean “Infinite” and “NEAR” respectively;
focusing is adjusted as per the distance (i.e., object distance) of the observed view, till the
scenery is clear.
Please don’t touch the surface of the lens when operating it, and please clean the dust or
poll

utants (if any) on the lens with special cleaning cloth.

Appendix II: Use of Desiccant

The desiccant bag is included in the accessories packed along with the product. Place
the desiccant in the equipment cavity after installation and electrical connection of the
equipment. Please pay attention to the placement position: keep away from driving
and electrical connection parts, and be relatively static and tight, so as to avoid the line fault
or driving fault due to absorption saturation of the desiccant.
