for the cabling cavity, and pull the hander
to open the cover of the cabling cavity.

Installing the Power Cable
1. Prepare RRU power cable connectors. DC RRU: Add a tool-less female connector (pressfit type) to the
RRU power cable by referring to the description of preparing cables delivered with the RRU.
2. Connect the tool-less female connector (pressfit type) at one end of the RRU power cable to the power
supply socket at the bottom of the RRU.
Installing a DC Power Cable
• When the remote distance of the RRU is more than 40 m
but less than or equal to 100 m, the RRU is connected to
the 3.3 square-meter DC power cable and then to the 8.2
square-meter DC power cable on the power supply device
through an OCB adapter.
• Ensure that the exposed shield layer of the power cable is
properly tightened using the cable clip.
2. Open the cable clip.
Pull the cabling cavity cover
to the hanging position.
The 1+3+3 waterproof is required for
AC cable connectors on the eRRU side.
Note that the waterproof tape on the
eRRU3232 (AC) side must be wrapped
away from the four fastening screws on
the bottom of the power connector. After
wrapping the tape upwards to the
connector bottom and connecting it to a
flange base, use cable ties to bind the
two ends of the tape.
