12.7 Grounding outputs

Either the positive or negative output terminals can be grounded. To avoid noise problems caused by common-mode current flowing from the load to ground, it is recommended to ground the output terminal as close as possible to the power supply's output. Always use two wires to connect the load to the power supply regardless of how the system is grounded.
