INSTALLATION AND WIRING
• FR-F720P-7.5K, 11K, FR-F740P-7.5K, 11K
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-F720P-15K, FR-F740P-15K or higher
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)
.
CAUTION
· Be sure to use the inverter with the jumpers across terminals R/L1 and R1/L11, and S/L2 and S1/L21 removed when supplying
power from other sources. The inverter may be damaged if you do not remove the jumper.
· 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.
· The power capacity necessary when separate power is supplied from R1/L11 and S1/L21 differs according to the inverter
capacity.
· If the main circuit power is switched OFF (for 0.1s or more) then ON again, the inverter resets and a fault output will not be held.
