If the length of the hybrid cable is adequate for the installation:
1) For all power cables, leave 1000 mm from where the double-layer sheath has been
peeled off and cut the excess length off.
2) Unsheathe the end of the power cable wire at 15 mm length.
3) 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.
4) From the inside of the cabinet, pull the optic cable to the right side of the system and
attach temporarily with a cable tie.
5) Using a flat-head screwdriver (-, 1x100), turn the RRH power terminal’s screw
counter-clockwise 2 to 3 times.
6) Insert the power cable to the terminal according to its usage and polarity, then fasten
the screw.
7) Bind two cables (-48 V, RTN) at 100 mm from the terminal using a cable tie.
8) Bury the optic cable following the system’s inner-right wall up to the UADU#0 side
and bind using a cable tie.
9) Connect the connector of the optic cable to UADU’s designated port. (Loop the optic
cable’s excess length respecting the bending radius (R=110 mm), and arrange it at the
bottom of the DC power terminal. Be careful not to damage the optic cable during
other works.)
