| (1) |
Wire both the inverter main power circuit and control circuit. |
| (2) |
Set  (external signal) at function code  . Next, set (voltage input (terminal 12) (0 to +10VDC)), (current input (terminal C1) (+4 to 20mADC)),  or other value at function code  .

| (1) Run/Stop |
: |
Operate the inverter across terminals FDW and CM short-circuited, and stop with open terminals. |
| (2) Frequency setting |
: |
Voltage input (0 to +10VDC), current input (+4 to 20mADC)

| Note1: |
When connecting a DC reactor (DCR), first remove the jumper between terminals [P1] and [P+]. A DCR is optional for inverters below 75HP for 208V, 100HP for 460V but standard for inverters of 75HP for 208V, 100HP for 460V or above. For inverters of 75HP for 208V, 100HP for 460V or above, be sure to connect a DCR. |
| Note2: |
To protect wiring, insert a molded case circuit breaker (MCCB) or a ground fault circuit interrupter (GFCI) (with overcurrent protection) of the type recommended for the inverter between the commercial power supply and the inverter. Do not use a circuit breaker with a capacity exceeding the recommended capacity. |
| Note3: |
In addition to an MCCB or GFCI, insert, if necessary, a magnetic contactor (MC) of the type recommended for the inverter to cut off the commercial power supply to the inverter. Furthermore, if the coil of the MC or solenoid comes into close contact with the inverter, install a surge absorber in parallel. |
| Note4: |
To put the inverter on standby by making the control circuit only active with the main circuit power supply being opened, connect this pair of wires to terminals [R0] and [T0]. Without connecting this pair of wires to these terminals, you can still run the inverter as long as the main wires of the commercial power supply to the main circuit are properly connected. |
| Note5: |
Normally no need to connect. Use these terminals when the inverter is equipped with a high power factor PWM converter with a regenerative facility. |
| Note6: |
You can select the frequency command source either electronically by supplying a DC voltage signal (within the range of 0 to 10 V, 0 to 5 V, or 1 to 5 V) between terminals [12] and [11], or manually by connecting a frequency command potentiometer to terminals [13], [12], and [11]. |
| Note7: |
For the wiring of the control circuit, use shielded or twisted wires. When using shielded wires, connect the shields to earth. To prevent malfunction due to noise, keep the control circuit wires as far away as possible from the main circuit wires (recommended distance: 4 inch(10 cm) or longer), and never put them in the same wire duct. Where a control circuit wire needs to cross a main circuit wire, route them so that they meet at right angles. |
