Location Guidelines; Site Surveys; Safety - ABB MicrOS 410 Installation Manual

Note
Ethernet data cable installations having lengths greater than 140 feet in the outdoor environment must use
a UL497 approved (UL/CSA/TUV Listed) primary protection device at the building entrance. Ethernet data
cable installations having lengths less than 140 feet in the outdoor environment may use a UL497A (UL/
CSA/TUV Listed) secondary protection device at the building entrance. TropOS Data Protection Device
and Network Protection Units are UL497A secondary protection devices.

Location Guidelines

MicrOS 410 devices are radio devices and therefore susceptible to interference that can reduce
throughput and range. Install the unit in an area where trees, buildings, and large steel structures
do not obstruct radio signals to and from the antenna. Direct line-of-sight operation is best.

Site Surveys

Due to variations in component configuration, placement, and physical environment, each
installation is unique. Before installing the MicrOS 410, perform a site survey to determine the
optimum placement of units for maximum range, coverage, and network performance. Consider
the following factors when performing a site survey:
Data rates—Sensitivity and range are inversely proportional to data bit rates. The maximum
radio range is achieved at the lowest workable data rate. A decrease in receiver threshold
sensitivity occurs as radio data rate increases.
Antenna orientation—The MicrOS 410 uses a directional antenna that must be aimed at its
Wi-Fi router.
Physical environment—Clear or open areas provide better radio range than closed or filled
areas. The less cluttered the operating environment, the greater the range.
Obstructions—A physical obstruction, such as a building or tree, can block or hinder
communication. Avoid locating the MicrOS 410 in a location where there is an obstruction
between sending and receiving devices.
Building materials—Radio penetration is influenced by the building material used in
construction. For example, drywall construction permits greater range than concrete blocks.

Safety

Installing the MicrOS 410 can pose a serious hazard. Be sure to take precautions to avoid the
following:
Exposure to high voltage lines during installation
Falls when working at heights or with ladders
Injuries from dropping tools and equipment
Contact with AC wiring
