Reduce Chemical Exposure
Before installing any devices in a chemically harsh environment, contact the manufacturer for more information regarding the life-expect-
ancy. Solvents, oxidizing agents, and other chemicals will damage the devices.
Minimize Mechanical Stress
Although these radio devices are very durable, they are sophisticated electronic devices that are sensitive to shock and excessive load-
ing.
• Avoid mounting the devices to an object that may be shifting or vibrating excessively. High levels of static force or acceleration may
damage the housing or electronic components.
• Do not subject the devices to external loads. Do not step on them or use them as handgrips.
• Do not allow long lengths of cable to hang from the glands on the Gateway or Node. Cabling heavier than 100 grams should be
supported instead of allowed to hang from the housing.
It is the user’s responsibility to install these devices so they will not be subject to overvoltage transients. Always ground the devices in
accordance with local, state, or national regulations.
Installation Quick Tips
The following are some quick tips for improving the installation of wireless network components.
Create a Clear Communication Path
Wireless communication is hindered by radio interference and obstructions in the path between the transmitter and receiver. To achieve
the best radio performance, carefully consider the installation locations for the Gateways and Nodes and select locations without obstruc-
tions in the path.
For more information about antennas, please refer to the Antenna Basics reference guide, Banner document p/n 132113.
Increase the Height of the Antennas
Position the external antenna vertically for optimal RF communication. If necessary, consider changing the height of the SureCross radio,
or its antenna, to improve reception. For outdoor applications, mounting the antenna on top of a building or pole may help achieve a line-
of-sight radio link with the other radios in the network.

Avoid Collocating Radios
When the radio network’s master device is located too close to another radio device, communications between all devices is interrupted.
For this reason, do not install a Gateway device within two meters of another Gateway or Node.
