3-2 DUT Test Connections Series 2600 System SourceMeters Reference Manual

Input/Output terminal blocks
The Keithley Instruments Series 2600 uses screw terminal blocks for input and
output connections to DUTs (Devices Under Test). The Model 2602/2612 uses
two terminal blocks as shown in
Figure 3-1 (one for each SMU channel). The
Model 2601/2611 has only one terminal block for the single SMU.
A terminal block can be removed from the rear panel by loosening the two captive
retaining screws and pulling it off the rear panel. Each screw terminal can
accommodate from 24 AWG (0.2mm
2
) to 12 AWG (2.5mm
2
) conductors.
After making the wire connections from a terminal block to a DUT, re-install the
terminal block onto the rear panel connector and tighten the two captive screws.
WARNING 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 2600
while the output is on. Power off the equipment from the front
panel or disconnect the main power cord from the rear of the
SourceMeter 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 an SMU is 250V.
Exceeding this level could damage the instrument and create a
shock hazard. See “
Floating an SMU” later in this section for
details on floating the SMUs.
The Input/Output terminals of the SourceMeters are rated for
connection to circuits rated Installation Category I only, with
transients rated less than 1500V peak. Do not connect the
SourceMeter terminals to CAT II, CAT III, or CAT IV circuits.
Connections of the SourceMeter Input/Output terminals 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 SourceMeter,
when connecting to a source with a greater current capability
than the Series 2600, a fuse should be provided in line with the
SourceMeter Input/Output terminals rated no more than 3A.
