4 FIRST POWER-UP AND START-UP

This chapter describes how to:
Check and prepare the braking module before power-up.
„
How to power up and check the success of the power-up.
„
How to set the braking module to work according to the network used in the
„
application.

4.1 START-UP PREPARATION

The braking module must have been already installed according to the
recommendations listed in Chapter 3 – Installation and Connection.
DANGER!
Always disconnect the main power supply before performing any
braking module connection.

4.1.1 Cautions during Power-Up/Start-up

1. Check all panel connections.
2. Check if there are short-circuits in the input, DC link, etc.
3. Check the state of all fuses.
4. Check all groundings (panel, doors, etc.).
5. Remove from inside the braking module or the cabinet all the materials left behind
from the installation work.
6. Close the braking module or cabinet covers.

4.2 START-UP

1. Set the line voltage according to the braking module model, as per table 3.3, by
means of DIP switches S1 located on the CDB1 board.
2. Set the desired braking actuation level, according to table 3.4, by means of DIP
Switch S2 located on board CDB1.
3. Measure the line voltage and verify if is within the allowed range.
4. Power up the inverter. The LEDs "DC Voltage", "+15 V" and "DI enable" (see figure 3.10)
must turn ON. The other LEDs must be OFF.
5. Check the correct operation of the fan.
6. Check for the presence of faults in the relay outputs and LEDs. If any fault occurs,
check for the possible cause and correct the problem.
