ECLIPSE INSTALLATION MANUAL
Installation Procedure
1. Fit the rack mounting brackets to the chassis with the grounding stud to left
or right side for the most direct ground wire path to the rack ground bar.
2. Locate the INU/INUe in the equipment rack and secure it using four No.12
Phillips dome-head screws from the IDC installation kit.
3. Ground the INU/INUe from the grounding stud to the rack/frame ground
bar using a length of 4mm2 (AWG12) green PVC insulated stranded copper
wire with a suitably sized ground lug at the ground bar end (supplied by the
installer). The grounding stud accommodates ground cables up to 16 mm
2
(AWG 6). The stud also provides jack plug connection for a wrist strap.
4. If the equipment rack/frame requires grounding, use 16mm2 (AWG6) wire
from its ground bar to the station ground.
Grounding Safety:
o
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.
Ground wires must provide a direct, low impedance path to the master
ground bar.
o
Do not connect other equipment to the same grounding cable as the INU.
Each item of equipment in a rack must be separately grounded to the rack
ground bar.
o
The INU must be located in the same immediate area (adjacent
racks/cabinets) as all other equipment with a (ground) connection to a
common DC supply source.
For NEBS compliance:
o
Install the fan air filter option. Options are available for the 1RU INU and
2RU INUe. See FAN Air Filter Option on page 66.
o
Install the NEBS power line filter unit. Install immediately below or above
the INU. Separate filter units are required for the NCC and, where fitted,
the NPC. Use the supplied 2w2 to 2w2 cable to connect the output of the
filter unit to the input of the NCC or NPC.
o
To ground the INU use 16 mm2 (AWG 6) green PVC insulated stranded
copper wire together with a star washer under the grounding screw at the
ground-bar end. Torque the INU grounding post screw to 1.2-1.5 Nm (10-13
in-lbs).
o
All bare conductors must be coated with an appropriate antioxidant
compound before crimp connectors are fitted.
o
All unplated connectors, braided strap, and bus bars must be brought to a
bright finish and then coated with an antioxidant before they are
