INSTALLATION AND WIRING
2.2 Wiring
2.2.1 Terminal connection diagram
3-phase 575V power input
Note:1. If the potentiometer is to be operated often, use a 2W1k
Ω
potentiometer.
2. Terminals SD and SE are isolated.
3. Terminals SD and 5 are common terminals. Do not ground them to the ground.
4. When terminals PC-SD are used as a 24VDC power supply, be careful not
to short these terminals. If they are shorted, the inverter will be damaged.

When using current input as the
frequency setting signal, set "4" in
any of Pr.180 to Pr.183 (input
terminal function selection) and
assign AU (current input selection)
to any of terminal RH, RM, RL, or
MRS, then turn the AU signal on.
