withstanding the maximum short circuit output current of the power
supply without causing overheat.
⚫ If several loads are provided, each pair of load wires shall safely
withstand the rated short circuit output current of the power supply
under full load.
⚫ Always use test lines provided by ITECH to connect the equipment.
If test lines from other factories are used, please check that the test
line can withstand maximum current.
Specification for Test Cables
Test cables are not standard accessories for the instrument. Please select
optional red and black test cables for individual sales based on the maximum
current value. For specifications of test cables and maximum current values,
refer to A.1 Specifications of Red and Black Test Cables for more information.
Connecting the DUT (Local Measurement)
The instrument supports two kinds of wiring methods with the DUT: local
measurement and remote measurement (SENSE). The default test mode is
local measurement.
NOTE
The T7830-350-180 consists of two 15kVA in parallel mode. The output terminals
and Remote sense terminals use the master port. The wiring method is the same
as other models.
Please confirm that the Remote Sense function in the menu is set to Off,
otherwise the instrument will report an error in the present connection mode.

NOTE
When the output voltage has DC voltage, the output terminal L is positive, and N is
negative.
