4 FIRST TIME POWER-UP AND START-UP
This chapter describes how to:
Check and prepare the rectifier before power-up.
Power-up the rectifier and check the result.
Set the rectifier for the operation with the power supply chosen for the application.
4.1 PREPARE FOR START-UP
The rectifier must have been already installed according to the recommendations listed in
. The following recommendations are applicable even if the application
design is different from the suggested control connections.
DANGER!
Always disconnect the main power supply before performing any connection.
4.1.1 Precautions During the Energization/Start-up
1. Verify all the connections of the panel.
2. Search for short-circuits at the input, DC bus, etc.
3. Verify the condition of all the fuses.
4. Inspect all the ground connections (panel, the door where the control is installed, etc.).
5. Remove all the remaining extra material from the inverter or panel interior.
6. Close the rectifier or panel covers.
4.2 START-UP
1. Set the power supply voltage according to the rectifier model, as presented in
through the DIP switches located in the CIR11 board.
2. Measure the line voltage making sure it is inside the permitted range.
3. Energize the control (+24 Vdc power supply). The LED + 12V_ON must light. The remaining LEDs must
be off.
4. Command the panel, perform the DC link pre-charge and close the main contactor/circuit breaker.
5. Verify the proper operation of the fans.
