Installation

WARNING There are potentially hazardous voltages (± 200 V for HPSMU, and ± 100 V for

MPSMU/HRSMU) present at the Force, Sense, and Guard terminals of this

instrument. To prevent electrical shock, the following safety precautions must

be observed during the use of the instrument.

• Use a three-conductor AC power cable to connect the instrument to an

electrical ground (safety ground).

•If you do not use the B1500A-A5F/16442A/B test fixture, you must install

and connect an interlock circuit that opens the Interlock terminal when the

shielding box access door is opened.

• If you change the DUT interface, test fixture, prober, and such, connect an

interlock cable to the one actually used.

• Confirm periodically that the interlock function works normally.

• Before touching the connections on the Force, Guard, and Sense terminals

in the test fixture or the shielding box, turn the instrument off and

discharge any capacitors. If you do not turn the instrument off, complete all

of the following items, regardless of the instrument settings.

• Press the front panel Stop key to set the module output off.

• Confirm that the front panel High Voltage indicator is not lit.

• Open the Interlock terminal (open the access door).

• Discharge any capacitors connected to a measurement resource.

• Warn persons working around this instrument about dangerous conditions.
