5.1 PREPARATION AND ENERGIZATION

The converter 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 UP11 G2 or UP11W
G2 used on the drive,
2. Configure the number of UP11 G2 or UP11W G2 connected in parallel through DIP switch S2 located on the
ICUP board, according to
3. Check if the power, grounding and control connections are correct and firm.
4. Remove all the materials left inside the drive.
5. Check all grounding connections (panel, door where the control is installed, etc.).
6. In the case of UP11W G2 (water-cooled):
a. Make a pressure test on the Cooling System to check for leaks.
b. Turn on the Cooling System and set the flow and the incoming water temperature according to the values
of Table 3.19 on page
c. Keep the water flowing for five minutes and check for leaks on the hydraulic connections.
7. Energize the control (supply +24 Vdc).
8. Close the panel doors.
9. 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.
10. Measure the voltage of the line and check if it is within the allowed range, according to
DATA on page 8-1.
11. Check that the automatic hardware identification has recognized the converter current properly, parameter
P0295. The converter current must be compatible with the number of power units installed.
12. Set parameter P0296 according to the rated voltage of the input line.
13. Command the drive, pre-charge the link, and close the main circuit breaker/contactor.
14. Enable the PWM pulses via DI.
15. Check that the DC link voltage indicated in P0004 is close to the P0151 value.
16. Check the success of the energization.
