56 Operating Manual for XFR 2.8kW Series Power Supply
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.
