l Waterproofing antenna cables and connectors
Make sure that the antenna, antenna extension cables and arrestor wring including the ground-
ing cable are connected properly. Protect the connectors and the arrestor with tape. As described
in C5.4.1 Mounting ISA100.11a Antenna to YFGW510, wind self-bonding tape and vinyl tape
around connections.

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 antenna 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 antenna extension cable.
Basically, the wireless LAN antenna must be at least 1 m away from the ISA100.11a antenna.
In a wireless LAN redundant model, the wireless LAN antennas must be at least 1m 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.
Installing wireless LAN antennas
n
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.
