Installation Overview The information below is an overview for installing the unit and auxiliary equipment. Unpack and inspect the equipment. Perform a pre-installation function check test of the equipment, and configure parameters. Pay particular attention to environmental conditions at the site, ventilation requirements, and grounding and lightning protection. Install the equipment at the site.
You may customize unit parameters such as TX/RX frequency, TX power and signalling, according to user needs. After configuration of parameters is complete, you may perform site installation. Installation Requirements 1. Environmental Conditions at Intended Installation Site The unit may be installed in any location suitable for electronic communication equipment, provided that the environmental conditions do not exceed the equipment specifications for temperature, humidity and air quality.
air to enter and exit. If several unit are installed in a single cabinet, ensure ventilation opening surrounding each unit allow for adequate cooling. All cabinets must have at least 10cm of open space between the air vents and any wall or other objects. When multiple cabinets (each equipped with several unit) are installed in an enclosed area, ensure appropriate ventilation and consider air conditioning or other climate control equipment, to satisfy the temperature requirements stated above. 3.
Installation Steps You will need a Philips screwdriver (cross head screwdriver), a Torx (T10) screwdriver and a spanner, to install the unit. Caution: Be sure to observe proper electrostatic discharge precautions if any part must be removed from the unit. The installation steps are as follows: 1. Mount the unti in a rack, bracket or cabinet. 2. Connect accessories such as antenna cables and power cords to the unit.
3. Loosen the screw at the back of the top cover, and then pull the top cover to remove it. 4. Loosen the 6 screws locking the PA heatsink, remove all power, data and RF cables from the PA, and finally remove the PA heatsink. 5. Mount the duplexer, and fasten the 2 screws inside the housing and on the side panel respectively. Then mount the PA heatsink, and connect all the lines and cables.
Ensure RF cables are properly connected between the duplexer and RF connectors.
Screws RF cables Screws Duplexer Mounted with Front Side Facing Downwards Electrical Connections After the unit has been mechanically inst alled, electrical connections must be made. This involves making the following connections: DC power cord Antenna cables See the rear panel view for the positions of connectors. Power Supply Connections 1. Ground Connection The unit is equipped with a ground screw located on the rear panel. Connect ground wires to the screw. 2.
The Unit may be connected to a regulated DC power supply or a backup battery. The DC source or battery backup system is connected to the unit through the DC power inlet at the rear of the unit (see rear panel view). Caution: Before you make the connection, ensure the DC power supply or battery backup system is capable of supplying a minimum of 200W, and check if the DC power supply has current limit.
2. Antenna Selection The selection of antenna is also critical to system performance. The selected antenna must be 50 Ohm impedance and capable of at least 50W. High gain antennas may be used to increase system coverage. Please take note of licensing restrictions when selecting high gain antennas. Some services or regions may have antenna gain or system radiation limitations. The antenna must be connected to the duplexer with a high grade 50 Ohm transmission line (e.g. Andrew HELIAX cables).
