4. Advanced Operation
 Cable connection for remote sensing
WARNING
 Before connecting the cable, turn off this product including its peripherals.
CAUTION
 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 (for example,
the signal at the secondary side of transformer) into the sensing input terminal.
 For the polyphase model or the polyphase output of Multi-phase model, 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 (for example, load end) using
a cable. In the Multi-phase model, the sensing input terminal is common to each output phase
configuration (single-phase two-wire, single-phase three-wire, and three-phase four-wire). The
terminals to be used for each output phase configuration are shown in Figure 4–24. Do not connect
anything to the terminals that are not used.
Used for the single-phase two-wire output
Used for the single-phase three-wire output
Used for the three-phase four-wire output
