Output connections
Feed the output pairs in through the bottom of the RPI and
route the pairs to the output connectors as shown in the
following illustration. If only one pair is used for powering a
Base Station, connect the power pair to -PWR(1) and
+PWR(1). If two pairs are used to power a Base Station,
connect one pair to -PWR(1) and +PWR(1), and the second
pair to -PWR(2) and +PWR(2).

given RPI installation.
Ensure both pairs have the same polarity.
