5 FIRST TIME POWER-UP AND START-UP

5.1 START-UP PREPARATION

The inverter must have already been installed according to
page 12.
DANGER!
Always disconnect the main power supply before making any connection.
1. Check if the power, grounding and control connections are correct and firm.
2. Remove all the materials left behind from the installation work from inside the inverter or the cabinet.
3. Verify the motor connections and if its voltage and current are within the inverter rated value.
4. Mechanically uncouple the motor from the load. If the motor cannot be uncoupled, make sure that any speed
direction (forward or reverse) will not result in personnel injury and/or equipment damage.
5. Close the inverter or cabinet covers.
6. Measure the power supply and verify if it is within the allowed range, according to
SPECIFICATIONS on page
7. Apply power to the input: close the input disconnecting switch.
8. Check the result of the first time power-up, the HMI display indicates:

5.2 START-UP

This section describes the power-up of the inverter with HMI operation, using the minimum connections of
3.1 on page 14 and without connections in the control terminals. Furthermore, two types of control will be
considered: V/f control (scalar) and vector control V V W. For further details on the utilization of these types of
control refer to the CFW100 programming manual.
DANGER!
High voltages can be present, even after the disconnection of the power supply. Wait at least 10
minutes for full discharge.
