This section describes how to prepare a site before eA680-208 installation. Select a site and space for installing an eA680-208 that meets the following requirements to ensure installation, commissioning, and operating of the equipment.
1. Requirements for Site Selection
To ensure long-term reliability of an eA680-208, 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:
a. Keep the site away from high temperature, dusty location, poisonous gases, explosive objects, and unstable voltages.
b. Keep the site away from any electric substation, industrial boiler, and heating boiler.
c. 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 eA680-208 can shield.
d. Keep an outdoor eA680-208 site 500 m away from the sea.
e. Keep the site away from pollution sources. If this is not possible, deploy the site in perennial upwind direction of pollution sources.
f. Keep the site at least 5 km away from heavy pollution sources such as a refinery and coal mine.
g. 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.
h. Keep the site at least 2 km away from light pollution sources such as a food factory and a leather processing plant.
i. 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.
j. Keep indoor eA680-208 sites 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.
k. Deploy an indoor eA680-208 site higher than the second floor in a building. Alternatively, mount an eA680-208 at least 600 mm higher than the record flood stage.
2. Requirements for Installation Space
To facilitate O&M, adhere to the following space requirements as shown in Figure1.
