2: General operation Series 2600B System SourceMeter® Instrument
2-50 2600BS-901-01 Rev. C / August 2016
Hazardous voltages may be present on the output and guard terminals. To prevent
electrical shock that could cause injury or death, never make or break connections to the
Series 2600B while the output is on. Power off the equipment from the front panel or
disconnect the main power cord from the rear of a System SourceMeter
®
instrument before
handling cables connected to the outputs. Putting the equipment into standby does not
guarantee the outputs are not powered if a hardware or software fault occurs.
Maximum floating (common mode) voltage for a SMU is 250 V. Exceeding this level could
damage the instrument and create a shock hazard. See Floating a SMU later in this section
for details on floating the SMUs.
The input/output connectors of the System SourceMeter
®
instrument are rated for
connection to circuits rated Measurement Category I only, with transients rated less than
1500 V peak. Do not connect the Series 2600B terminals to CAT II, CAT III, or CAT IV
circuits. Connections of the input/output connectors to circuits higher than CAT I can cause
damage to the equipment or expose the operator to hazardous voltages.
To prevent electric shock and/or damage to the System SourceMeter
®
instrument, when
connecting to a source with a greater current capability than the Series 2600B, a user-
supplied fuse, rated at no more than 20 A SLO-BLO, should be installed in-line with the
Series 2600B input/output connectors.
