This chapter describes how to:
- Check and prepare the inverter before power-up.
- Power-up the inverter and check the result.
- Set the inverter for the operation in the V/f mode based on the
power supply and motor information by using the Oriented
Start-Up routine and the Basic Application group.
NOTE!
In order to use the inverter in VVW or vector control modes, and for other available functions, refer
to the CFW-11 programming manual.

5.1 START-UP PREPARATION

The inverter must have been already installed according to the recommendations listed in Chapter 3 - Installation
and Connection. The following recommendations are applicable even if the application design is different from
the suggested control connections.

1) Check if power, grounding, and control connections are correct and firmly secured.
2) Remove from inside the inverter or the cabinet all the materials left behind from the installation work.
3) Verify the motor connections and if its voltage and current are within the inverter rated values.
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 voltage and verify if it is within the allowed range, according to the chapter 8.
7) Apply power to the input:
Close the input disconnect switch.
