l Fastening antenna wiring
After taping, fasten the cables to a solid structure to protect against vibration and wind. Ensure
that the radii of bends in the cables do not fall below the limits above.
C5.4.3 Installation and Wiring of Wireless LAN Antenna
The wireless LAN antenna must be connected to YFGW510 using an extension cable in order to
prevent interference with the ISA100.11a antenna and to mount the antenna vertically. To fasten
the antenna, use the brackets provided with the extension cable.
Basically, the wireless LAN antenna must be at least 1 m away from the ISA100.11a antenna. In
a redundant wireless LAN system, the wireless LAN antennas must be at least 30 cm away from
each other. When wireless LAN antennas or the ISA100.11a antenna is located near a mounting
pipe or any other metal object, allow clearance of at least 30 cm.
n Installing wireless LAN antennas
Install the wireless LAN antenna in an appropriate location for wireless communication, referring
to requirements on distance from the ISA100.11a antenna, and C3.1 Requirements for Installa-
tion Locations. Make sure that the mounting of the antenna on a 2-inch pipe has enough strength
to withstand strong winds and vibration. The antenna must be kept upright.
l Fastening wireless LAN antenna
Fasten the wireless LAN antenna to the pipe using the brackets provided with the antenna. When
mounting on a vertical pipe, make sure that the antenna stands higher than the top of the pipe.
