High-Current Output Connections - Keysight Technologies N6705C Operating And Service Manual

2 Installation
For Keysight N678xA SMU power modules – Remove the 12A connector plug from the wire harness
and install the 8-pin connector plug provided with the power module. Install the front panel cable
wires in the output connector as shown. Observe the output color code. Tighten all connector screws.
For Keysight N6781A and N6785A power modules, also connect the auxiliary measurement cable.
Remove the cable from its rear panel storage location and insert the connector into the power
module. The cable's color code corresponds to the AUX voltage measurement label on the rear panel.

Step 4. Finish the installation.
Place any unused cable harnesses in the clip ring located between the power modules and the front
panel. Install the top and bottom covers. Push the covers into place and tighten the thumbscrews.

High-Current Output Connections

This information only applies to power modules with output current ratings of 50 A.
Do not connect the front panel cable assembly to the high-current output power
modules. Because the front panel binding posts have a maximum current rating of 20
A, they are not available for use with high-current power modules.
High-current (50 A) load connections are made using the rear panel access ports of the mainframe.
These access ports have a thin rubber membrane which can be pierced using the load wires.
User-supplied load and sense wires must be used to connect to the output and sense connector plugs
on the high current power module.
Step 1. Route the load wires through the rear panel.
Push the high-current load wires through the rear panel access port. If you are using remote sensing,
route the sense wires though the second access port. Twist each wire pair.
Step 2.Connect the wires to the power module.
Connect the load wires to the output connector of the power module as shown. Connect the sense
wires to the sense connector.
