4-1 Preparation Procedure
1. Installation:
Install the Inverter according to installation conditions. Refer to page 3-2
.
Check that all the installation conditions are met.
2. Wiring:
Connect the Inverter to power supply and peripheral devices. Refer to page 3-6
.
Select peripheral devices that meet the specifications, and wire them correctly.
3. Turning the Power On:
Check the necessary items, then turn the power on.
Always check that the power voltage is correct and the power input terminals (R, S,
and T) are wired correctly.
S
Power voltage
200-VAC class: Three-phase, 200 to 230 VAC, 50/60 Hz
400-VAC class: Three-phase, 380 to 460 VAC, 50/60 Hz
When a 3G3EV-AB
jjj
is used in single-phase input mode, the power voltage
must be as follows: single-phase, 200 to 240 VAC, 50/60 Hz (use terminals R and
S)
Check that the motor output terminals (U, V, and W) and motor are connected cor-
rectly.
Check that the control circuit terminals and controller are connected correctly.
4. Checking Display Status:
Check the Inverter for errors.
If everything is normal, the indicators below become as follows when the power is
turned on:
S
RUN indicator: Flashing
S
ALARM indicator: Not lit
S
Constant item indicators: “FREF,” “FOUT,” or “IOUT” is lit.
S
Data display: Data corresponding to the constant item indicators is displayed.
If an error exists, the ALARM indicator lights up. In this case, take the necessary ac-
tion as described in Section 5 Operation.
5. Setting Constants:
