Connection of the sensing cable
Possible electric shock or damage to the internal circuitry.
•
Never wire the cable to the sensing terminals while the POWER
switch is turned on.
• For sensing cables, use cables with a higher voltage rating than the
isolation voltage of the PAT. Protect the uncovered section of the
shielded wire by using insulation tubes with a withstand voltage
greater than the isolation voltage of the PAT. For the isolation
voltage of each model, see Chapter 9, “Specifications.”
• The sensing terminals are at approximately the same potential as
the - (neg.) output terminal of the PAT. Insert the wire so that the
wire scraps protruding from the sensing terminals do not come in
contact with the chassis. Also, insert wires to the terminals so that
the stripped sections do not protrude from the terminals.
If the sensing wires come loose, the output voltage across the load cannot be
stabilized and may cause excessive voltage to be applied to the load. If an
appropriate OVP trip point is set, the OVP trips and prevents excessive voltage
output.
After you are done using the remote sensing function, remove the sensing wires, and
be sure to turn off remote sensing using the sensing switch.

You can check the sensing switch status using the CONFIG settings (CF02).

Notes when connecting the sensing cable
Use AWG24 wires to connect to the sensing terminals. Remove 10 mm of the wire
covering.
