Installation, Connection and Energization
1. Check if all the power, grounding and control connections are correct and tightened.
2. Clean the inverter internally, remove all packing material and installation residues from within the MVW3000
cabinets.
3. Check all motor connections and verify whether its voltage, current and frequency match the inverter
specifications.
4. If it is possible, decouple the motor mechanically from the load. If the motor cannot be decoupled, then make
sure that rotation in any speed direction (Forward or reverse) is not hazardous to people or to the machine.
5. Close and lock the panel doors.
6.3.2 Initial Power-up (Parameter Settings)
After the preparation for power-up, the inverter can be energized, according to the following steps:
Make sure:
1. The auxiliary power supply voltage and the medium voltage supply line voltage are available in the input
switchgear. Check that the low voltage auxiliary power supply voltage that feeds the control panel is within the
allowed range (rated v 10 %/-15 %).
2. The control panel circuit breakers are installed according to the electrical project. Then closes the door of the
control panel.
3. The emergency button is not activated.
4. The control panel was energized, the switch-disconnector of the control panel auxiliary power supply is closed,
and check the initialization of the main control through the HMI.
5. The first power-up was successful, the initialization process was completed and the status of the HMI is
indicating inverter ready.
6.3.3 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 MVW3000 inverter. The inverter should have
already been installed and programmed, according to
Chapter 6 INSTALLATION, CONNECTION
AND ENERGIZATION on page 6-1 .
DANGER!
„
Des tensions élevées peuvent être présentes même après déconnexions de l’alimentation.
„
La séquence suivante est valable pour l’onduleur du MVW3000 standard. L’onduleur doit déjà
avoir été installé et programmé, comme décrit respectivement dans le
Chapter 6 INSTALLATION,
CONNECTION AND ENERGIZATION on page 6-1 .
6.3.3.1 Start-up with HMI Operation and V/F 60 Hz Control Mode
1. Apply power to the panel close the disconnector switch at the control column power supply input.
2. Once the control panel is energized, the main control board will go into the initialization process, and the HMI
will show the message “booting”:
- After the control has finished its initialization (approximately 10 seconds), the message “Inverter in Undervoltage”
is presented on the HMI.
