4.2 Powering Up the Drive
Review the following table before applying power.
Item to Check Description
Power supply voltage
200 V class: Three-phase/Single-phase 200 to 240 Vac 50/60 Hz
400 V class: Three-phase/Single-phase 380 to 480 Vac 50/60 Hz
600 V class: Three-phase/Single-phase 500 to 600 Vac 50/60 Hz
Properly wire the power supply input terminals (R/L1, S/L2, T/L3).
<1>
Check for proper grounding of drive and motor.
Drive output terminals and
motor terminals
Properly wire drive output terminals U/T1, V/T2, and W/T3 with motor terminals U, V, and W.
Control circuit terminals Check control circuit terminal connections.
Drive control terminal status Open all control circuit terminals (off).
Status of the load and connected
machinery
Decouple the motor from the load.
<1> Confirm the following when connecting models 4A0930 and 4A1200: Remove the jumpers on R1/L11, S1/L21, and T1/L31 when using 12-phase
rectification. Refer to 12-Phase Rectification on page 97 for details. When operating without 12-phase rectification, properly wire terminals R1/
L11, S1/L21, and T1/L31 in addition to terminals R/L1, S/L2, and T/L3.

Setting the Real Time Clock
The time and date must be set when a new HOA keypad is plugged in and the drive is powered up. The HOA keypad will
display the time and date setup screen for 30 seconds. If a button is not pressed during this time, the display will clear and a
“Clock Not Set” alarm will flash. Pressing the F2 (Data) key will display the setting screen again.
n
Feedback Loss Wire Break Alarm
If there is no sensor wired to the drive, a “Feedback Loss – Wire Break” alarm will flash on the display. Providing the proper
feedback device signal will clear the Feedback Loss alarm.
The drive requires a feedback device (e.g., pressure transducer, flow meter, etc.) to perform automatic system regulation. Any
analog 0~10 V or 4-20 mA feedback device can be used in combination with the drive.
Note: The factory default setting for the drive is 4~20 mA feedback device connected to analog input A2.

Real Time Clock Setting Display
Note: Setting the Real-Time Clock will clear a “Clock Not Set” alarm.
