VOLUME III, CHAPTER 3, INU AND INUE INSTALLATION
Power Cables
The INU power cable is supplied in the IDC Installation Kit. It is supplied with a D-
sub M/F 2W2 connector fitted at one end and wire at the other. The cable is nom-
inally 5m (16ft), and the wires are 4mm2 (AWG12).
The cable is used for -48 Vdc connections to an NCC or NPC, or for +24 Vdc con-
nections to a PCC.
The blue wire must be connected to live (-48 Vdc or +24 Vdc); the black wire to
ground (+48 Vdc or -24 Vdc).
Figure 3-2. Power Cable and Connector
CAUTION:DC power connector can be shorted inadvertently if applied
at an angle. Always insert with correct alignment.
The PCC is supplied with a power cable to connect to an NCC or NPC.
Similarly, the optional NEBS power line filter unit is supplied with a power cable to
connect to an NCC, NPC, or PCC.
This cable is fitted with a D-sub M/F 2W2 connector at each end. Note that a stand-
ard power cable is not included for the reason the cable supplied with an NCC (or
NPC) is not used when powered from a PCC, or via a power line filter, so the cable is
re-used as the power input cable for the PCC or filter unit.
Fuses
The NCC and NPC are fitted with a fast-acting 25A fuse fitted on the PCB behind the
power cable connector.
The PCC is fitted with a fast-acting PCB-mounted 20A fuse.
NCC, NPC and PCC fuses are not field-replaceable.
FAN Air Filter Option
A fan air filter option is available for installation with the FAN module in an INU,
and with the 2RU FAN module in an INUe. Where Eclipse is required to be NEBS
