Sorensen SLM-Series DC Load Installation
M540071-01 Rev C 2-3
2.1.2 Removal
CAUTION: PREVENT DAMAGE TO THE MODULE CIRCUITRY. Do NOT remove the
plug-in module while the mainframe is under power.
1. Turn the SLM mainframe power OFF.
2. Using a screwdriver, loosen the screw on the lower right corner of the front panel.
3. Turn the adjustment knob of the black binding post counter-clockwise until it is fully loosened.
4. Pull on the black adjustment knob of binding post until the interconnecting jack at the rear of
the load module disengages.
5. Finish pulling the SLM-series DC load module out from the mainframe.

Connections
2.2.1 Input Binding Post and Wire Considerations
The output of the device under test (DUT) can be connected to the load by one of five methods, each
described in the following subsections. The positive (+) and negative (-) binding posts should be
connected to the wires/cables according to the following guidelines. A major consideration in making
input connection is the wire size. The minimum wire size is required to prevent overheating and to
maintain good regulation. It is recommended that the wires be large enough to limit the voltage drop
to less than 0.5V per lead.
Note
: When using Constant Resistance mode, Vsense inputs should be used to keep cable
resistance from affecting measurements and regulation.
CAUTION: PREVENT DAMAGE TO THE LOAD. Do NOT apply voltage or current with
power switched OFF. Turn ON the power switch to the load PRIOR to applying voltage or
current to the input terminals (i.e., before turning on the power supply under test).
Plug Connectors
This is the most popular way to connect the input of electronic load to the device under test. It is
recommended the load current be less than 20A in this connection since the current rating of
the plug is rated to 20A. The maximum wire gauge should be limited to AWG14.
Hook Terminals
The hook terminal provides a good contact to the binding post and can be used anytime. The
maximum wire gauge should be limited to AWG10.
Direct Insertion into Binding Posts
This is the most convenient way to connect the load input to the DUT. The maximum wire gauge
AWG14 can be used in this application.
