There are 4 reference poles for the 8 outputs. A pair of outputs share
a reference pole as shown below.
Each group of 2 outputs is electrically isolated from the others.

IMPORTANT
If an unused channel is defined as a current output (software
configuration set to current output), the output channel has to
be short-circuited. Place jumpers into these outputs and tighten
the screws.
IMPORTANT
If an unused channel is defined as a voltage output (software
configuration set to voltage output), the unused outputs must be
left open. Short-circuiting a unused voltage output may cause
damage to the output.
