Output Connections
Turn the unit off before connecting any wires.

Outputs 1 - 4

Disconnect the mating plug from the unit by pulling it straight back.
The output connectors (outputs 1-4) have a termination for the Hi and Lo output terminals, the Hi and Lo
sense terminals, a guard terminal, and an earth ground terminal (see figure 2-3). For proper operation of
the dc source, you must connect the Hi sense and Lo sense terminals to their respective high and low
monitoring points. Install the connector plug with its sense terminals connected before applying power to
the unit.
CAUTION: Connect the sense leads carefully so that they do not become open-circuited. If the sense
leads are left unconnected or become open during operation, the dc source will revert to
a local sense mode using internal sense protect resistors. This will result in an incorrect
voltage being applied at the load terminals.
The 6-pin connector is removable and accepts wires sizes from AWG 28 to AWG 16. Insert the wire into
the wire terminal, then use a small, flat-bladed screwdriver to tighten the wire terminal. Agilent
Technologies does not recommend using wire sizes smaller than AWG 24. After you insert the mating
plug into the output connector, tighten the two locking screws to secure the connection.

Figure 2-3. Remote Sense Connections
Figure 2-4 shows how to connect remote sense and load leads when using a removable test fixture. For
best transient response and load regulation, keep the resistance and inductance as low as possible, as
illustrated in the figure. The addition of a low-leakage RC network may help improve output transient
response when the unit is operating in voltage priority mode.
