For details on how to add the OT terminals to the DC RRU power cable, see page 47.

4. Closing the Cover Plate of theRRU Cabling Cavity.

The screw on the cover plate is tightened until the fastening torque is 14 kgf•cm.The screws on the cover plate are tightened in the order shown in the preceding figure.The tape is wrapped spirally upwards, downwards, and then

upwards again in three layers. For every two adjacent tape layers, the tape on the upper layer overlaps about half the width of the tape on the lower layer.Do not remove the dustproof cap from the feeder connectors that are not in use. In addition, protection measures against damp, dust, and salt mist must be taken. If the RRU is installed outdoors, you also need to wrap the joint with waterproof tape.

Press the strap on the exposed shielding layer of the power cable tightly. Ensure that the lower edge of the exposed shield layer does not exceed the position shown in the figure.The alarm cable is preferably led out of the RRU from the narrower cable trough in the middle of the cabling cavity. If the cable trough is used by the CPRI optical cable, the alarm cable is led from the wider cable trough near the middle one. In this case, the alarm cable must be wrapped with 10 to 17 layers of waterproof tape so that the diameter of the cable reaches 10 mm to 12 mm.To avoid sharp bending, the optical cable must be pressed by the strap next to the power cable during the optical cable installation.Waterproof fillers should be installed in the unused cable trough.
