Model 2636A noise shield (floating)
Safety shield
A safety shield must be used whenever hazardous voltages (
>
30 V
rms
, 42 V
peak
) will be present in
the test circuit. The safety shield can be metallic or nonmetallic, and must completely surround the
DUT test circuit. A metal safety must be connected to a known safety earth ground and chassis
ground. See
later in this section for important safety information on the use of a metal
or nonmetallic enclosure.
Model 2601A/2602A safety shield
The maximum output voltage for a Model 2601A/2602A channel is 40V, which is considered a non-
hazardous level. However, using two or more Model 2601A/2602A voltage sources in a series
configuration can cause test circuit voltage to exceed 42V. For example, the SMUs of two Model
2601A/2602A instruments can be connected in series to apply 80V to a DUT (see
).
The connections for the test configuration in
are shown in
. Use #18 AWG
wire or larger for connections to safety earth ground and chassis.
