Set the Jumpers
Each power supply module has two jumpers located at the back of the
power supply near the edge connectors. The jumper selection provides the
proper voltage regulation for the different power supply configurations.
The power supply can be configured to support local or remote sensing by
setting the jumpers.
To configure the supply:
1.
Position the power supply module so that the jumpers and pins are
facing upward (as shown in figure 1).
