Eclipse Installation Manual
Eclipse dc power, IF, tributary, auxiliary and NMS cables are not to be
routed with any AC mains power lines. They are also to be kept away
from any AC power lines which cross them.
13. Carry out a complete check of the installation. If all is correct, and the IRU 600 and
its waveguide, pressurization and antenna installation has likewise been completed
and checked, Eclipse is now ready for power-on. If a PCC is installed, ensure
the PCC to NCC/NPC cable is fitted before power-on.
Once powered up the RFU(s) will be transmitting with the pre-configured or
ex-factory frequency and power settings unless the start-up transmit mute
option has been invoked. (All RFUs shipped ex-factory have the
transmit-mute set as the default unless otherwise specified).
If frequency and power settings are not correct, interference can be caused
to other links in the same geographical area.
14. Power on for -48 Vdc by connecting the power cable to the NCC, and to the NPC
where fitted.
• For +24 Vdc operation, connect to the PCC input.
• Where a power line filter is installed (for -48 Vdc), connect to the filter input.
The 2W2 DC power connector can be shorted inadvertently if
applied at an angle. Always insert with correct alignment.
Next step: The Eclipse node is ready for configuration and antenna alignment.
