When connecting the DC RRU power cable to the DCDU-03B, you must add an OT terminal to the shielding
layer. Then, fix the OT terminal to the corresponding PGND terminal of the DCDU-03B. For details on how to
add an OT terminal, see page 37.
The DC RRU power cable is connected to one of the LOAD0 to LOAD5 terminals of the DCDU-03B.
