Safety considerations
The earth ground screw terminal of the Model 8009 Resistivity Test Fixture must
be connected to a known safety earth ground using the Model 8007-GND-3
ground wire, or #18 AWG or larger wire.
The use of hazardous voltage requires that interlock be used. The interlock circuit
is activated when the Model 6517-ILC-3 or the Model 6517B-ILC-3 interlock
cable (both supplied with the Model 8009) is connected as shown in Figures 2-3
and 2-4. Whenever the lid of the Model 8009 is open, the Model 6517 or Model
6517B will go into standby, thus removing power from the test fixture.
