Making J3 Connections

Some applications will use only the default factory connections on the J3 connector located on
the rear panel. Other applications will require replacing pin-to-pin connections or making
connections to external devices such as voltage sources, current sources, or resistances. Read
Section 2.2 Safety, and follow the procedures in this section whenever the rear panel
connector, J3, is to be reconfigured.
The steps to follow are:
Refer to the Dissipating Stored Energy and Powering Up steps in Section 4.2.3.
Making the Connection
To make pin-to-pin connections:
1. Unsolder any pin-to-pin jumpers as required by the application.
2. Solder new connections using any appropriate single bus wire such as AWG 20 to 24.
To connect external source leads, resistance leads, or monitoring or sense lines:
3. Unsolder any jumpers as required by the application.
4. Solder leads to the specified pin using the recommended wiring and/or grounding point
for the application. Pin, wiring, and grounding specifications for particular applications
can be found in Section 4 Advanced Operation except for remote sensing
specifications that are in Section 3.3 Using Remote Sensing.

Remote Programming: Output Voltage and Current Limit

Remote programming allows control of the power supply's output voltage and/or current limit to
shift from local operation at the front panel voltage and current controls to external analog input
