the output: Connect the cathode to the positive output and the anode to return. Where
positive load transients, such as back EMF from a motor might occur, or stored energy
is present such as a battery, a second blocking diode in series with the output is
recommended to protect the power supply. Refer to Figure 2-9.

Ensure that the chosen components are suitably rated for the inductance and energy
to be dissipated. The Peak Reverse Voltage ratings should be a minimum of 2 times
the Power Supply maximum output voltage. The Continuous Forward Current ratings
should be a minimum of 1.5 times the power supply maximum output current. A
heatsink may be required to dissipate the power caused by flow of current.

Rear Panel User Interface Connectors
The rear panel contains the connectors for the remote analog programming interface,
external user control I/O interface, digital communications interfaces (LAN, USB, RS-
232C, and optional GPIB IEEE-488).

Remote Analog programming
The remote analog programming connector is located on the rear panel for each
channel. Figure 2-10 shows the rear panel view of the connector for the three channels
and Table 2-10 lists the connector type. Table 2-11 shows the functions and Table
2-12 shows the connector pinout.
