RocketLinx WR7802-XT Series User Guide
: 2000638 Rev. A
Hardware Installation
•
The output voltage of the AC/DC to DC power supply conforms to the input voltage range of the WR7802-
XT.
•
Cables (wire) must be appropriate for the specified electronic voltage, current, wire diameter and
temperature range. Remember, the minimum wire diameter of AC voltage is at least 0.75mm(AWG18).
The minimum for DC voltage is at least 1.0mm (AWG16)).
•
Follow the power installation instructions in this guide, which indicates the input voltage, pin
assignment, connection circuit and notices.
•
Only power on the supply voltage to the WR7802-XT if the WR7802-XT housing is closed, the terminal
blocks are wired correctly and the terminal blocks are connected.
•
The WR7802-XT
MUST
be grounded. Ground the WR7802-XT before connecting the cables, antennas and
power supply. The grounding WR7802-XT and DC power supply may be different in some applications, if
this is case, you must ground them separately.
•
Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable
grounding is available.
Environment and Housing Notifications
•
Hot surface
. Avoid touching the WR7802-XT while it is operating.
•
Only operate the WR7802-XT at the specified ambient temperature and humidity. The temperature of the
surrounding air means a distance of up to 5cm from the WR7802-XT. When installing multiple devices
within the cabinet, leaving space between the devices is mandatory for better heat dispersement.
•
Install the WR7802-XT in the vertical position, with the antenna connections pointing upward.
•
Install the WR7802-XT in a cabinet or at an operating site with limited access. A 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 WR7802-XT housing. Without
the manufacturer’s permission, opening the housing means the product is not covered under warranty
and not responsible for any unexpected risk.
Installation Notifications
If you are installing the WR7802-XT in a field box or outdoor area, for your safety as well as others’, 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 WR7802-XT in an indoor office or factory, make sure that the WR7802-XT and
power source are properly grounded. A professional wireless IT Engineer can provide advice on the AP
location, channel, and field plan to get the best performance and coverage.
•
Connect the WR7802-XT 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 found on the web
site 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.
