5 Product installation
5.1 Lightning protection
When this product is installed in a high independent position, lightning protection measures must be
taken (as shown in the figure below). Please make sure to keep enough distance between RS - 485 and
video signal with high voltage pressure device or cable, when necessary, it is also important to apply
lightning protection, anti-surge protection measures, etc. This product must be installed according to
international GB50198 (Civil closed circuit monitoring TV system engineering and technical specification)
standard for reliable ground lightning protection, otherwise possible damage may be caused to the
product. The resistance between ground point and product should be less than 4Ω.
5.2 Cable
This product is packed along with an adapter with input of AC220V
±
10% and it must be grounded
safely. In the case of unstable voltage input, please take necessary operations before connecting to the
power supply in order to ensure that the product can work under working condition.
Please have notice that the switching power supply is not waterproof, therefore it should be
installed in the electrical distribution box under operating temperature between - 40
℃
~ + 60
℃
.
In order to avoid insufficient power supply voltage and normal operation of the equipment, the
distance between the power and equipment cannot be more than the values specified bellow:
