5 ENERGIZATION AND START-UP

This chapter explains:
How to check and prepare the inverter before energization.
„
How to energize and check the success of the energization.
„
How to program the inverter for operation in the V/f mode using the Oriented Start-up routine and the Basic
„
Application group.
NOTE!
In order to program the inverter in Vector or V V W mode and other existing functions, refer to the
Programming Manual of the CFW-11.

5.1 PREPARATION AND ENERGIZATION

The inverter must have already been installed according to
page 3-1. If the drive design is different from the typical drives suggested, the steps below may also be followed.
DANGER!
Always disconnect the general power supply before making any connections.
1. Configure DIP switch S1 located on the ICUP board, according to the rated voltage of the UP11W G2 used
on the drive, Table 3.25 on page
2. Configure the number of UP11W G2 connected in parallel through the DIP switch S2 located on the ICUP
board, according to Table 3.17 on page
3. Check if the power, grounding and control connections are correct and firm.
4. Remove all the materials left behind from the installation work from inside the inverter or drive.
5. Verify the motor connections and if the motor voltage and current are within the inverter rated value.
6. Make a pressure test on the Cooling System to check for leaks.
7. Turn on the Cooling System and set the flow and the incoming water temperature to the values of
on page 3-14.
8. Keep the water flowing for five minutes and check for leaks on the hydraulic connections.
9. Energize the control (supply +24 Vdc).
10. Close the panel doors.
11. The HMI must indicate undervoltage with the electronics energized and the power units de-energized. Parameter
P0004 (Voltage on the DC Link) will indicate approximately 15 Vdc.
12. Measure the voltage of the line and verify if it is within the allowed range, according to
DATA on page 8-1.
13. Verify if the automatic hardware identification recognized the current of the CFW-11W G2 inverter properly,
parameter P0295. The inverter current must be compatible with the number of power units installed.
14. Set parameter P0296 according to the rated voltage of the input line.
