Chapter 3. Eclipse Edge Installation
Installing the IDUspe
To install an IDUspe:
1. Fit the rack mounting ears to the IDU. Position the ear with the grounding stud to
left or right side for the most direct ground wire path to the rack ground bar.
2. Locate the IDU in the equipment rack and secure it using four No.12 Phillips
dome-head screws from the IDU installation kit.
3. Ground the IDU from the ground stud to the rack/frame ground bar using a length
of 4 mm
2
(AWG 12) green PVC insulated stranded copper wire with a suitably sized
ground lug at each end (supplied by installer).
4. If the equipment rack/frame requires grounding use 16 mm
2
(AWG 6) wire from
its ground bar to the station ground.
NOTE:
Do not assume that an existing rack or mounting frame is correctly
grounded. Always check the integrity of the ground connections,
which must include a check through to the master ground for the
station, which should be located at the point of cable entry to the
equipment building.
5. Fit the jumper cable, and trim it to the surge suppressor (if installed) or to the
RJ-45 socket-socket connector, for connection to the ODU cable. Terminate it with
the supplied RJ-45 plug.
Power Supply Compliance
and Loading
The dc power supply must be SELV UL or IEC compliant
(60 Vdc maximum output).
Check to ensure that connection of an Eclipse system to an
existing dc supply does not overload the supply, circuit
protection devices and wiring.
Where a new dc power supply is to be installed for an Eclipse
IDU, the power supply must be rated to supply a minimum
30W.
Power Supply Input Fuses
Each input, +ve and -ve, is protected by a PCB
surface-mounted 10A fast acting fuse. These fuses are located
immediately behind the power supply connector. They are not
field replaceable.
Grounding
The IDU must be grounded to the station or master ground,
which must be the same ground as used for the dc power
supply. Normally this is achieved by grounding the IDU to the
ground bar in its equipment rack or frame. This bar is most
often located to one side of the rack or at rack top or bottom.
In turn, the ground bar is grounded to the station ground.
The IDUspe must be grounded by its ground stud, which is
fitted to one of the rack ears. This is the primary ground for
the IDUspe. It can also be (additionally) grounded using the
ground wire connection on the power supply connector.
