Precautions for Equipment Operating Environment
The operating environment for the integrated LH complies with ETSI EN 300 019-1-3 class 3.2 standards.
Recommended operating environment
To ensure the reliability of equipment, an equipment room must be equipped with dedicated air conditioners to
control the temperature and humidity within the following ranges:
•Temperature: 15º C to 30º C ( 59℉ to 86℉ )
•Relative humidity: 40% to 75%
Basic operating environment
With stable temperature and humidity in an equipment room, the integrated LH can work under the following
conditions:
•Temperature: –5º C to +50º C ( 23℉ to 122℉ )
•Relative humidity: 5 % to 95%
Installation Precautions in a Harsh Environment
Definition of harsh environment
•More than 500m ( 1640 ft ) away from but within 3.7 km ( 12139 ft ) of an ocean or a salt water lake
Antenna anticorrosion requirements or measures
When outdoor equipment or cabinets are installed in a harsh environment, ensure that the following
requirements are met:
•If glue dispensing is not done on the rivets or screws of the center plate and reflective surface of an antenna
before delivery, apply matching outdoor adhesive to them.
•Apply thread adhesive to screws used for installing antennas. This can prevent the screws from becoming
loose and improve corrosion resistance.
•After you finish installing screws, spread oil or spray paint on the surface of the screws.
•In areas with many birds, install protective covers to prevent birds' droppings from corroding antennas.
