Input/output connectors
The 2600B uses screw terminal connectors or triaxial connectors for input and output connections to
devices under test (DUTs). The 2601B, 2602B, 2604B, 2611B, 2612B, and 2614B use screw terminal
connectors. The 2634B, 2635B, and 2636B use triaxial connectors.
A screw terminal connector can be removed from the rear panel by loosening the two captive
retaining screws and pulling it off the rear panel. Each screw in the terminal connector cable
assembly (used with the SMU connector) can accommodate from 24 AWG (0.2 mm
2
) to 12 AWG
(2.5 mm
2
) conductors.
Basic connection sequence:
1. With the output off and the connector uninstalled from the 2600B rear panel, make the wire
connections from a connector to the DUT.
2. Reinstall the connector onto the rear panel.
3. If using a screw terminal connector, tighten the two captive screws.
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 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 2600B 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
(on page 4-26) for
details on floating the SMUs.
The input/output connectors of the 2600B are rated for connection to circuits rated
Measurement Category I only, with transients rated less than 1500 V
PEAK
. Do not connect the
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 2600B, when connecting to a source with a
greater current capability than the 2600B, a user-supplied fuse, rated at no more than 20 A
SLO-BLO, should be installed in-line with the 2600B input/output connectors.
