With POWER switch OFF, connect the power cord of the ISOPACK to a 120 volt, 60Hz
outlet. The POWER switch gives on off control to the ISOLATED outlets only; the DIRECT
outlets are always “hot” whenever the ISOPACK is plugged into a live outlet.
Connect the power plug of the transformerless equipment to one of the ISOLATED outlets.
Select the desired output voltage as explained in Step 3 of the “AS A VARIABLE VOLTAGE
TRANSFORMER” section.
The chassis of the transformerless equipment may now be grounded, if desired, by connecting
a test lead between the chassis and the case of the ISOPACK or the ground pin of one of the
outlets
Set the POWER switch to ON. The pilot lamp will light and power will be applied to the
transformerless equipment.
Auxiliary equipment, such as test instruments, may be connected to the DIRECT outlets. Line
voltage, which is unaffected by either the VOLTAGE SELECT switches or the POWER ON
OFF switch, is available here.
The chassis of the transformerless equipment may be grounded or tied to a test equipment
common, through connection to the test equipment instead of the ISOPACK.
