Main Circuit Terminal Specifications
4.2.1 Terminal Arrangement of the Main Circuit Terminal, Power Supply and the Motor Wiring
Single-Phase 200 V Class
Three-Phase 400 V Class
CAUTION
앫
To prevent a malfunction due to noise, keep the signal cables more than 10 cm away from the power cables. Also separate the main circuit wire
of the input side and the output side.
앫
After wiring, wire offcuts must not be left in the inverter.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling mounting holes in a control box etc., take
care not to allow chips and other foreign matter to enter the inverter.
앫
Set the voltage/current input switch in the correct position. An incorrect setting may cause a fault, failure or malfunction.
앫
The output of the single-phase power input specification is three-phase 230 V.
FR-D720S-008SC to 042SC
FR-D720S-070SC and 100SC
FR-D740-012SC to 080SC
FR-D740-120SC, 160SC
CAUTION
앫
Make sure the power cables are connected to the R/L1, S/L2, T/L3 (three-phase 400 V class) resp. to the L1, N (for single-phase
200 V class). Never connect the power cable to the U, V, W of the inverter. Doing so will damaged the inverter. (Phase sequence
needs not to be matched.)
앫
Connect the motor to U, V, W. At this time turning on the forward rotation switch (signal) rotates the motor in the clockwise
direction when viewed on the motor shaft.
