Connecting the sensing cables
When using the sensing function, connect the sensing cables before connecting the load cables to the out-
put terminals.
If the sensing cables come loose, the output voltage will fluctuate. Because it may increase several tens of
volts higher than the specified value, be sure to set an appropriate OVP trip point.
If you are not going to use remote sensing, return the product to local sensing mode.
1
Turn the POWER switch off.
2
Remove 8 mm of the wire covering. Connect the negative sensing cable to -S that
will be used for remote sensing and the positive sensing cable to +S.
Insert the sensing cable towards the right according to the angle of the sensing terminal.
3
Turn on the SENSE switch on the front panel.

WARNING
• Never wire the sensing terminals while the POWER switch is turned on.
• For sensing cables, use cables with a voltage rating that is higher than the prod-
uct’s isolation voltage. Protect the uncovered sections of the shielded cable by
using insulation tubes whose withstand voltage is greater than the product’ isola-
tion voltage.
• Insert the cables so that the wire strands do not touch the chassis when they stick
out of the sensing terminal. Also, insert the cables so that the stripped wires do not
stick out of the terminal.
Be sure to attach the output terminal cover before turning the POWER switch on.
