1) Remove the upper screws.
2) Remove the lower screws.
3) Remove the jumper.
4) Connect the separate power
supply cable for the control
circuit to the upper terminals
(R1/L11, S1/L21).
• FR-F720-00630-NA or more, FR-F740-00310-NA or more
1) Remove the upper screws.
2) Remove the lower screws.
3) Pull the jumper toward you to
remove.
4) Connect the separate power supply
cable for the control circuit to the
upper terminals (R1/L11, S1/L21).
Never connect the power cable to
the terminals in the lower stand.
Doing so will damage the inverter.
CAUTION
1. Do not turn off the control power (terminals R1/L11 and S1/L21) with the main circuit power (R/L1, S/L2, T/L3) on. Doing
so may damage the inverter.
2. Be sure to use the inverter with the jumpers across terminals R/L1-R1/L11 and S/L2-S1/L21 removed when supplying
power from other sources. The inverter may be damaged if you do not remove the jumper.
3. The voltage should be the same as that of the main control circuit when the control circuit power is supplied from other than the
primary side of the MC.
4. The power capacity is 60VA or more for FR-F720-00770 (FR-F740-00380) or 80VA or more for FR-F720-00930 to 02330 (FR-
F740-00470 to 03610) when separate power is supplied from R1/L11, S1/L21.
5. When the power supply used with the control circuit is different from the one used with the main circuit, make up a circuit
which will switch off the main circuit power supply terminals R/L1, S/L2, T/L3 when the control circuit power supply
terminals R1/L11, S1/L21 are switched off.
