Installing the Outdoor Unit (ODU)
Tools and Test Equipment
Have on hand a standard electrician's tool kit and any tools listed in the antenna
manufacturer's installation instructions.
Site Considerations
The ODU is designed to mount on the antenna. Locate and install the antenna
according to instructions supplied by the antenna manufacturer. Choose an area that is
free of extraneous interference from motors and electrical equipment and has a clear
line of sight from the antenna to the satellite. Lightning arrestors should be used at the
site to protect personnel and equipment. Size 3/0 or 4/0 AWG stranded copper wire
should be used to ground the Tx Redundancy, Redundant PSUI and the Rx
Redundancy to the antenna frame and to the lightning protection ground rod. For the
higher power units with an external power supply provide an isolation filter to reduce
power line interference as required.
Preparation
Mounting Considerations:
Optional Mounting Brackets are available that will facilitate mounting for most antennas.
The ODU must be mounted such that:
- Sufficient support is afforded to the Tx Redundancy, the Rx Redundancy and the
Redundant PSUI’s to minimize the effects of antenna sway in strong winds.
- Air movement across the heat fins is possible.
- The fan shroud (IBUC and PSUI) is mounted so that the louvers are facing the
ground.
- The fan intake and exhausts are free from any obstruction.
- The length of the PSUI cables is taken into consideration in determining the
mounting location of the PSUI.
Throughout installation and during any polarization, azimuth or elevation adjustment,
ensure that cables and waveguide are not crimped or pinched.
Power Requirements
Installation and connection to the line power
supply must be made in compliance with
applicable wiring codes and regulations.
