Installation
Local and Remote Sensing
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.
