cracking of the plastic sheath of the cable. All cables should be laid and installed
when the temperature is above zero.
If the storage temperature of the cable is below zero, the cable must be moved
to room temperature and stored for more than 24 hours before laying and
installation.
When carrying cables, especially in a low-temperature environment, always
handle the cable with care. Violent handling, such as pushing down the cables
directly from a high place, is prohibited.
Electrical Safety

Notes and Cautions
2.8.1 Installation Notes
When the product needs to be installed on the rack, 4 screws (M5*12) should be
used to fix P20/P10 and 16 screws (M5*12) should be used to fix Q8. The rack for
installation shall bear at least four times the total weight of the mounted equipment.
a) Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly,
the operating ambient temperature of the rack environment may be greater than
room ambient. Therefore, consideration should be given to installing the
equipment in an environment compatible with the maximum ambient
temperature (Tma) specified by the manufacturer.
b) Reduced Air Flow - Installation of the equipment in a rack should be such that
the amount of air flow required for safe operation of the equipment is not
compromised.
c) Mechanical Loading - Mounting of the equipment in the rack should be such that
a hazardous condition is not achieved due to uneven mechanical loading.
d) Circuit Overloading - Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits
might have on overcurrent protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be used when addressing
this concern.
e) Reliable Earthing - Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections other
than direct connections to the branch circuit (e.g. use of power strips).

reproduced by a device to a standard color model, usually the RGB
model.
Bit Depth

the bit depth of an image, the more colors it can store.
Frame Rate
Frame rate (expressed in frames per second, or FPS) is the frequency
(rate) at which consecutive images called frames to appear on a
display. Frame rate may also be called the frame frequency, and be
expressed in hertz.
DSK

an image, allowing that portion of the image to be replaced. This color
can be any solid color, most commonly blue or green.
