DC-S3283EX Explosion-proof Speed Dome camera
VII
Ex structure instruction
We have made adequate consideration in flameproof enclosure design of the
explosion-proof camera to prevent explosive gases getting into the inner
volume, the explosion inside the enclosure cannot cause the explosion of the
external explosive gases. We ensure the explosion-proof performance by
strengthen enclosure the strength, adjust the length and gap of the joint of
associate components and limit the maximum surface temperature.
The enclosure is able to subject to static pressure test (1.5 times for at least
10s) specified in EN60079-1/IEC60079-1, no leakage or deformation allowed
after test.
The maximum surface temperature will no more than 80ºC in normal operation.
Tempering glass is adopted in observation port, the tempering glass shall pass
the impact and thermal shock test.
Ingress protection level: IP66, IP68(2m/2h).
Protection the flameproof surface in maintaining of this product, otherwise the
damaged flameproof surface will affect the Explosion-proof performance.
When the product needs anti-corrosion treatment (especially carbon steel), the
surface of the product will be sprayed. In this case, please wipe the
non-metallic layer with a damp cotton cloth during maintenance. Pay attention
to the protective coating. Do not use liquids with strong corrosion.
The light-transmitting parts of this product have static electricity risk. When
wiping lens parts of this product, it is necessary to ensure that it is carried out in
a safe environment. Do not wipe with dry cloth.
