3 Installation order
This section defines safety rules, installation recommendations, setup procedure and the device starting
procedure.
3.1 Safety rules
Do not open the device case. There are no user serviceable parts inside.
Do not install the device during a thunderstorm. There is a risk of lightning stroke.
You must follow requirements for voltage, current and frequency specified in the user manual.
Measuring devices and computer must be grounded before connecting to the device. The electric potential
differnce between devices' cases should not exceed 1 V.
Make sure that all the cables are intact and they are reliably attached to connectors.
You should satisfy established standards and requirements for working at height during the device
installation on the high-rise constructions.
The device exploitation should be performed by specially prepared engineering and technical personnel.
Connect only to operational service equipment.
3.2 Installation recommendations
Recommended location for device installation: communications mast/pole.
Before you install and enable device, check the device for visible mechanical defects. If defects are
observed, you should stop the device installation, draw up corresponding act and contact the supplier.
Install the device vertically on communications mast or pole in the way that the LAN port is pointed down.
In order to provide better receiving signal level, the sectoral antenna of a base station should be in line of
sight of WB-2P-LR5. You may achive the highest signal level by antenna alignment with the help of RSSI
indicators.
The transmitting part of the device is located on the other side from brackets. This area should be directed
to base station sectoral antenna.
After adjusting, make sure that level of the received signal from the base station should be no more than -65 ÷ -70
dBm. Decreasing this level up to -75 dBm is permitted if it does not involve the use of VoIP, streaming video and
other traffic that is sensitive to losses in a wireless network.
3.3 WB-2P-LR5 mounting
3.3.1 Pre-tuning
Before installing, proceed pre-tuning of the device (see section
device (paragraph 2-7, section
) and follow the instructions given in the section
. Make sure that the user station connects required wireless network: RSSI indicators should be on.
3.3.2 Mounting algorithm
1. Install the device on communications mast/pole pointing LAN port down as it is shown on the figure below.
Attach the device using clamps supplied in the device package. Comply the safety rules and
recommendations given in
.
Install the device on communications mast/pole so that the device is directed to base station sectoral
antenna as much as possible. There must also be direct visibility to the base station.
