ECLIPSE INSTALLATION MANUAL
The following steps describe the procedure for installing the power cable, and pre-
paring for power-on. Do not connect the power until all steps have been completed.
8. Run the supplied power cable through to the power pick up point, which
will normally be at a circuit breaker panel in the rack. A circuit breaker (or
fuse) should have a capacity of 12A for the INU and a 25A for the INUe,
however these ratings can be adjusted in line with the number of cards
installed, and hence power consumption. For power consumption data, see
Power Supply on page 72.
9. For a -48 Vdc supply, connect the blue wire to -48Vdc (live), and the black
wire to ground/+ve. (Power input on the NCC and NPC is polarity
protected).
10. For a +24 Vdc supply, connect the blue wire to +24Vdc (live), and the black
wire to ground/-ve. (Power input on the PCC is polarity protected).
11. Measure the voltage on the dc power connector.
o
For -48 Vdc operation the voltage should be -48Vdc, +/-2Vdc for a non
battery floated supply, and nominally -56 Vdc for a battery floated supply.
(Limits are -40.5 to - 60 Vdc).
o
For +24 Vdc operation the voltage should be 24 +/- 2Vdc for a non battery
floated supply, and nominally 30 Vdc for a battery floated supply.
(Operating limits are 20 to 36 Vdc).
CAUTION:This product meets the global product safety requirements
for SELV (safety extra low voltage) rated equipment and the input
voltage must be guaranteed to remain within the SELV limits (60V
maximum) in the event of a single internal fault.
Always check the integrity of the dc power supply to an INU/INUe
right to its source. Never assume that the supply provided to the pick-
up point in a rack is correct.
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.
12. Carry out a complete check of the installation. If all is correct, and the ODU
600 installation has likewise been completed and checked, the INU and
ODU 600 are ready for power-on.
o
If a PCC is installed, ensure the PCC to NCC/NPC cable is correctly fitted
before power-on.
CAUTION:Once powered up the ODU(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 ODUs shipped
ex-factory have the transmit-mute set as the default unless oth-
erwise specified).If frequency and power settings are not correct,
interference can be caused to other links in the same geographical
area.
13. Turn power on. For -48 Vdc connect the power cable to the NCC, and to the
NPC where fitted. For +24 Vdc operation, connect to the PCC input.
CAUTION:Do not turn off an INU/INUe within 10 minutes of initial
turn-on, or initial turn-on after a new compact flash card is installed.
