4. To prevent ground loops, ground the sense line shield, at one point
only, to the power supply’s return output connection at the load, to the
power supply’s return output at its negative output terminal, or to the
power supply’s chassis.
5. Turn the power supply ON.
Notes:
1. If you operate the power supply with remote sense lines connected to
the load and with either of the positive or negative load lines not
connected, the power supply shutdown circuit will activate, causing
the output voltage and current to fall to zero.
2. If you operate the power supply without remote sense lines or local
sense jumpers in place, the supply will continue to work, but supply
regulation will be degraded and/or erratic, or, the OVP circuit may
activate.
Figure 2-12 shows a sample setup for using remote sensing.
