10.3.2 Initial Power-up (Parameter Settings)

After the pre-power checks the inverter can be powered up:
1. Verify the supply voltages
Verify whether the medium voltage line is available at the input cubicle.
Measure the auxiliary low voltage power supply voltage that feeds the control column and make sure it is within the allowed limits of
+10 %/-15 %).
2. Check the control column circuit breakers
Verify if the settings of the control circuit breakers are according to the electric project.
Close the control column door.
3. Verify the emergency pushbutton
Make sure the emergency pushbutton is not actuated. In case it is actuated, use the safety key to unlock it.
4. Apply power to the control column
Close the control column auxiliary supply disconnector switch only after the power-up process be concluded.
5. Verify the first energization success
The first time the panel is energized or when the factory settings are loaded with (P0204 = 5), the guided startup routine is initiated. This routine
asks the user to program some parameters regarding the inverter and the motor.

10.3.3 Start-up

This section describes the inverter start-up with keypad operation. The considered control mode is V/F 60 Hz.
DANGER!
High voltages may be present even after the power supply disconnection.
The following sequence is valid for the standard MVW01 inverter.
The inverter should have already been installed and programmed, according to
TION AND ENERGIZATION on page 10-1
DANGER!
Des tensions élevées peuvent être présentes même après déconnexions de l'alimentation.
La séquence suivante est valable pour l'onduleur du MVW-01 standard.
L'onduleur doit déjà avoir été installé et programmé, comme décrit respectivement dans le
CONNECTION AND ENERGIZATION on page 10-1

10.3.4 Start-up - HMI Operation - Control Mode: V/F 60 Hz

1. Apply power to the panel close the disconnector switch at the control column power supply input.
2. Once the control column has been energized, the MVC1 or MVC3 control board waits for its initialization, presenting the following
message on the HMI: - After the control has finished its initialization (approximately 10 seconds), the message "Inverter in Undervoltage"
is presented on the HMI.
At this moment the inverter is in undervoltage state (DC link is discharged) and the "Ready to Start" pilot light (H1) at the control column
door is on, indicating that it is already possible to initiate the inverter pre-charge.
3. Initiate the pre-charge / power section energization.
The MVW01 inverter pre-charge command must be given manually:
With the pilot light "READY TO START" on, press the "POWER-ON" pushbutton (S1).
Wait until the pre-charge is finished (approximately 10 seconds). During the pre-charge the "PRECHARGE" pilot light (H2) must
remain on.
Once the pre-charge is successfully completed, the "PRE-CHARGE" pilot light goes off and the "INPUT ON" (H3) goes on, indicating
that the input transformer circuit breaker was successfully closed.
The "Inverter Ready" message is displayed on the HMI.
