 When setting Remote sensing to FB, the load cable connected to the output terminal should be
as short as possible (3 m or less) with twisted or parallel wire.

 Cable connection for remote sensing

Before connecting the cable, turn off this product including its peripherals.
 Pay attention to the withstand voltage of the cable to be connected.
 Do not connect anything to the terminals that are not used.
 Do not input a signal having a different electric potential from the output terminal (e.g. the
signal at the secondary side of transformer) into the sensing input terminal.
 For the polyphase output, cables should be connected to the sensing input terminals N1, N2, and
N3 for each phase. These terminals do not have the same electric potential within this product.
Connect the sensing input terminal to the output voltage detecting end (e.g. load end) using a cable.
The sensing input terminal is common to each output phase mode (single-phase two-wire,
single-phase three-wire, and three-phase four-wire). The terminals to be used for each output phase
mode are shown in Figure 4-24. Do not connect anything to the terminals that are not used.
