4.1 Site Preparations
This section describes how to prepare a site before EG860 installation.
Select a site and space for installing an EG860 that meets the following requirements to ensure
installation, commissioning, and operating of the equipment.
Requirements for Site Selection
To ensure long-term reliability of an EG860, select a site based on the network plan and technical
requirements of the equipment, as well as considerations such as hydrology, geology, and
transportation.
Site selection must meet the following requirements:
l
Keep the site away from high temperature, dusty location, poisonous gases, explosive
objects, and unstable voltages.
l
Keep the site away from any electric substation, industrial boiler, and heating boiler.
l
Keep the site away from any radar station, large-power radio transmitting station, and other
interference sources. The field strength of interference sources cannot exceed that of
unwanted radiation that an EG860 can shield.
l
Keep an outdoor EG860 site 500 m away from the sea.
l
Keep the site away from pollution sources. If this is not possible, deploy the site in perennial
upwind direction of pollution sources.
l
Keep the site at least 5 km away from heavy pollution sources such as a refinery and coal
mine.
l
Keep the site at least 3.7 km away from moderate pollution sources such as a chemical
plant, a rubber plant, and an electroplating factory.
l
Keep the site at least 2 km away from light pollution sources such as a food factory and a
leather processing plant.
l
The air intake vents of the communication equipment must be far away from the sewer
pipe, septic tank, and sewage disposal pool. The atmospheric pressure inside the equipment
room must be higher than that outside the equipment room. Otherwise, corrosive gases may
enter the equipment room and corrode the components and circuit boards.
l
Keep an indoor EG860 site away from livestock rearing houses and fertilizer warehouses.
If this is not possible, the room must be located at a place that is in the upwind direction of
the livestock room or fertilizer warehouse.
l
Deploy an indoor EG860 site higher than the second floor in a building. Alternatively,
mount an EG860 at least 600 mm higher than the record flood stage.
