2 Installation

To configure the power supply for remote sensing:

Turn off the power supply.

Remove the local sense jumpers from the J2 connector.

Connect the negative sense lead to terminal 5 (-S) and the positive sense lead to terminal 1 (+S). Make sure that the connector plug is securely inserted into the connector body.

Turn on the power supply.

NOTE

If the power supply is operated with remote sensing and either the positive or negative load wire is not connected, an internal protection circuit will activate and shut down the power supply. To resume operation, turn the power supply off, connect the open load wire, and turn on the power supply.

Load Considerations

Multiple Loads

The following figure shows multiple loads connected to one power supply. Each load should be connected to the power supply’s output terminals using separate pairs of wires. It is recommended that each pair of wires will be as short as possible and twisted or shielded to minimize noise pick-up and radiation. The sense wires should be connected to the power supply output terminals or to the load with the most critical load regulation requirement.
