After loosening the hex nut, connect the earth-bonding cable between the two
washers as illustrated in the figure above. Then, fasten all parts again with the hex
nut.

nut.
The PE cables must have a minimum cross section of 16 mm

.
3.2.4. Connection to the Main Unit
In order to connect the Extension Unit (EU) with the Main Remote Unit (RU), use a
cable bridge. Connect this cable bridge at the extension connector of the EU
(illustrated in 3.2.2 Connections) with the corresponding connector to EU at the RU.
Which connector to EU of the RU is exactly used is described in the corresponding
User’s Manual for the RU.
3.2.5. Connection of RF Cables to Combining Unit
The remote unit has N-connectors for connection to the Combining Unit. For its
location, please refer to chapter 3.2.2 Connections. For mounting the cable
connectors, it is recommended to refer to the corresponding documentation of the
connector manufacturer. The bending radius of the RF cables must remain within the
given specifications.
For the selection of cable and antenna it should be considered that, on the one hand,
a cable with higher loss is less expensive but, on the other hand, it impairs
performance.

performance.
Use an appropriate torque wrench for the coupling torque of N-type
connectors (2 N-m / 20 in lb), with 13/16 in opening to tighten the N-type
antenna connectors. For example, use torque wrench of item no. 244379
available from the Andrew e-catalog. Do NOT use your hands or any
other tool (e.g. a pair of pliers)! This might cause damage to the
connector and lead to a malfunction of the Remote Unit.

To minimize passive inter-modulation (PIM) distortion, attention has to
be paid to the physical condition of the connector junctions. Do not use
connectors that show signs of corrosion on the metal surface. Prevent
the ingress of water into the connector. Attach and torque the
connectors properly.
