Use remote sense:

3.18 Three-phase parallel setup


SL，SN: remote sense terminal

L，N: rear panel output terminals, the same as the front panel output
terminals.

X: connectionless
NOTE
When the output voltage has DC voltage, the output terminal L is +, and N is -.
Use the "Remote Sense" function to compensate the voltage drop of the wire
between the rear panel terminal and tested equipment. Operations are as
follows:
1. Disconnect the wires/short clips between L and SL, N and SN.
2. Connect the SL to the DUT's L terminal, and connect the SN to the
DUT's N terminal.
3. Connect one pair of drive wires from the rear panel terminals L and N to the
tested equipment.
NOTE
In order to ensure the stability of the system, using armored twisted pair cable between
the remote sense terminal of IT7600 and DUT.
IT7600 can be used in parallel connection of multiple units to test three-phase
AC power supplies.In three-phase parallel applications, the user can select the
Y-type and Δ-type connection according to the actual requirements. Flexible
connection can meet various test requirements.
Under Parallel mode, the output power cannot exceed 90% of the total power to
avoid loss caused by AC power unbalance.
