Front-panel connector
Front-panel connectors are available to connect load wires for bench operation. A chassis ground
binding post is also provided on the front panel.
Figure 22: Front-panel binding post
There are two locations on the binding post to connect the wire. See the picture above. You can use
one of the methods below to connect the outputs from the front panel:
Insert standard banana plugs into the front connectors as shown in location 1.
Insert safety test leads into the front connectors as shown in location 1. For details, see the
following figure.
Insert the wires into the hole as shown in location 2, and fasten the wires by hand-tightening the
binding posts. The wire size should be from American wire gage (AWG) 20 to AWG 12.
Figure 23: Safety test lead connection
The wire must be heavy enough not to overheat while carrying the short-circuit output
current of the unit. You must meet the wiring requirements described above. Make sure the
wire you use is enclosed inside a safety cover.
