2.8.2 Connecting DU Cabinet side cable
If the length of the hybrid cable is inadequate for the installation:
1) Measure the hybrid cable's excess length.
(With a white marker pen, mark the area of the cable where the double-layer sheath
will be peeled when positioned in the conduit fitting.)
2) Using a knife, peel off the heat shrink tube that binds the cables together.
3) Pull the peeling wire in the inside of the hybrid cable's double-layer sheath down to
the previously marked area.
4) Peel off the hybrid cable's sheath.
5) Peel off the aluminum foil wrapped around the inner cable.
6) For all power cables, leave 23.62 in. (600 mm) from where the double-layer sheath has
been peeled off and cut the excess length off.
7) Unsheathe the end of the power cable wire at 0.59 in. (15 mm).
8) Using a conduit, insert the hybrid cable's power cable and optic cable together into the
cabinet. Be careful not to damage the optic cable's connector.
9) From the inside of the cabinet, pull the optic cable to the right side of the system and
attach temporarily with a cable tie.
10) Using a flat-head screwdriver (-, 1x100), turn the RRH power terminal's screw counter-
clockwise twice to 3 times.
11) Insert the power cable to the terminal according to its use and polarity, then fasten the
screw with a torque of 1.3~1.59 lbf.ft (18~22 kgf.cm).
12) Bind two cables (-48 V, RTN) at 3.94 in. (100 mm) from the terminal using a cable tie.
13) Bury the optic cable following the system's inner-right wall up to the UADU#0 side
and bind using a cable tie.
14) Connect the connector of the optic cable to UADU's designated port. (Loop the optic
cable's excess length respecting the bending radius 'R=4.33 in. (110 mm)', and arrange
it in the cable tray box. Be careful not to damage the optic cable during other works.)
