Introduction
Environment and Housing
•
Hot surface
. Avoid touching the device while it is operating.
•
Only operate the device at the specified ambient temperature and humidity. The temperature of the
surrounding air means a distance of up to 5cm from the device. When installing multiple devices within
the cabinet, leaving space between the devices is mandatory for better heat dispersement.
•
Install the device in the vertical position, with the antenna connections pointing upward.
•
Install the device in a cabinet or in an operating site with limited access. The metal cabinet will filter the
radio signals. Use an extended antenna cable and install the external antenna in a free space that helps
provide a better radio signal.
•
Only technicians authorized by the manufacturer are permitted to open the housing. Without the
manufacturer permission, opening the housing means the product is not covered under warranty and not
responsible for any unexpected risk.
Installation
If you are installing the wireless equipment in the field box or outdoor area, for your safety as well as others’,
please seek assistance from a professional installer who has received safety training on the hazards involved.
Keep safety as well as performance in mind when selecting your installation site, especially where there are
electric power and phone lines.
Please note the following things as well:
•
Do not use a metal ladder;
•
Do not work on a wet or windy day;
•
Wear shoes with rubber soles and heels, rubber gloves, long sleeved shirt or jacket.
•
If you are installing the equipment in an indoor office or factory, make sure that the device and power
source are properly grounded. A professional wireless IT Engineer can provide advice for the AP location,
channel and field plan to get better performance and coverage.
•
Connect the equipment after verifying that the cabinet meets the appropriate IP degree of protection.
•
Read the radio output power, receiver sensitivity, antenna gain specifications before installation. The
shipped product and antenna conforms to the R&TTE Directive and is allowed for use in all European
countries. You can read the related technical specifications from the product data sheet or User Guide.
•
When installing external antennas, the Radio Output power and antenna gain value must meet the
regulations of the country.
•
When the system is operational with a high gain antenna, avoid standing directly in front of it. Strong RF
fields are present when the transmitter is on.
•
When the system is operational with a high gain antenna for short distance transmission, adjust the radio
output lower. Strong output power with a high gain antenna is not a proper installation method for short
distance transmission.
•
You are responsible for undertaking suitable lightning protection.
•
Install over voltage protector devices on every outdoor Ethernet cable.
•
Protect each antenna installed outside with lightening protection devices, for example, a lightening
arrester.
Note that Field EMD (Lightning) DAMAGE IS NOT COVERED UNDER WARRANTY.
